Description

CROSS REFERENCE TO RELATED APPLICATION

This application claims priority to U.S. Provisional Application No. 62/770,314, filed Nov. 21, 2018, which is hereby incorporated by reference in its entirety.

FIELD OF THE DISCLOSURE

The disclosure relates to the field of plant breeding and, more specifically, to the tomato variety NUN 09225 TOF. The disclosure further relates to vegetative reproductions of tomato variety NUN 09225 TOF, methods for tissue culture of tomato variety NUN 09225 TOF, methods for regenerating a plant from such a tissue culture, and to phenotypic variants of tomato variety NUN 09225 TOF. The disclosure also relates to progeny of tomato variety NUN 09225 TOF and the hybrid varieties obtained by crossing tomato variety NUN 09225 TOF as a parent line with plants of other varieties or parent lines.

BACKGROUND

The goal of plant breeding is to combine various desirable traits in a single variety. Such desirable traits may include greater yield, resistance to diseases, insects or other pests, tolerance to heat and drought, better agronomic quality, higher nutritional value, enhanced growth rate and improved fruit properties.
Breeding techniques take advantage of a plant's method of pollination. There are two general methods of pollination: self-pollination and cross-pollination. A plant self-pollinates if pollen from one flower is transferred to the same or another flower of the same genotype. A plant cross-pollinates if pollen comes to it from a flower of a different genotype.
Plants that have been self-pollinated and selected for (uniform) type over many generations become homozygous at almost all gene loci and produce a uniform population of true breeding progeny of homozygous plants. A cross between two such homozygous plants of different lines produces a uniform population of hybrid plants that are heterozygous for many gene loci. The extent of heterozygosity in the hybrid is a function of the genetic distance between the parents. Conversely, a cross of two plants each heterozygous at a number of loci produces a segregating population of hybrid plants that differ genetically and are not uniform. The resulting non-uniformity makes performance unpredictable.
The development of uniform varieties requires the development of homozygous inbred plants, the crossing of these inbred plants to make hybrids, and the evaluation of the hybrids resulting from the crosses. Pedigree breeding and recurrent selection are examples of breeding methods that have been used to develop inbred plants from breeding populations. Those breeding methods combine the genetic backgrounds from two or more plants or various other broad-based sources into breeding pools from which new lines are developed by selfing and selection of desired phenotypes. The new plants are evaluated to determine which have commercial potential.
Tomato (Solanum lycopersicum and closely related species) is naturally a diploid and the basic chromosome number of the genus is x=12, most are 2n=2x=24, including the cultivated ones. It originated in the New World and has since become a major food crop.
Tomato cultivars may be grouped by maturity, i.e., the time required from planting the seed to the stage where fruit harvest can occur. Standard maturity classifications include ‘early’, ‘midseason’ or ‘late-maturing.’ Another classification for tomatoes is the developmental timing of fruit set. ‘Determinate’ plants grow foliage, then transition into a reproductive phase of flower setting, pollination and fruit development. Consequently, determinant cultivars have a large proportion of the fruit ripen within a short time frame. Growers that harvest only once in a season favor determinant type cultivars. In contrast, ‘indeterminate’ types grow foliage, then enter a long phase where flower and fruit development proceed along with new foliar growth. Growers that harvest the same plants multiple times favor indeterminate type cultivars.
Tomatoes can also be classified by their target markets: fresh market and processing tomatoes. Fresh-market tomatoes are primarily used for salads, salad bar and sandwiches, and require good storage properties. On the other hand, processing tomatoes generally requires red colored and pink to red/crimson fruit flesh and higher percentage of soluble solids. Processing tomatoes can be canned whole, canned, diced or chopped, dried, roasted, pasted, puréed or concentrated, juiced, frozen, or put into ready-made dishes, for example, sauces, stews or soups.
In 2017, World Atlas (available at world-wide web word atlas under articles/which-are-the-world-s-leading-tomato-producing-countries) reported that the worldwide production of tomatoes amounted to 170.8 million tons. United States is ranked as the third largest producer of tomatoes in the world, next to China and India. Tomatoes are available in the United States year-round, with California and Florida being the major producers. Fresh-market tomatoes are available from May to December although supply peaks in July and in September through October. Processing tomatoes have the greatest supply from August to September.
In response to more recent consumer demands for dietary diversity, tomato breeders have developed a wider range of colors. In addition to expanding the range of red colored fruits, there are cultivars that produce fruits that are creamy white, lime green, yellow, green, golden, orange and purple. Additionally, there are multi-colored varieties exemplified by mainly red fruited varieties with green shoulders, and both striped- and variegated-colored fruit.

“UPOV descriptors” are the plant variety descriptors described for tomato in the “Guidelines for the Conduct of Tests for Distinctness, Uniformity and Stability, TG/44/11 (Geneva 2011, revised 2018 Oct. 30), as published by UPOV (International Union for the Protection of New Varieties and Plants), and which can be downloaded from the world wide web at upov.int/under edocs/tgdocs/en/tg044.pdf and is herein incorporated by reference in its entirety. Likewise, “UPOV methods” to determine specific parameters for the characterization of tomato are described at upov.int.
“Calibration book for Tomato (Lycopersicon esculentum Mill.)” refers to the calibration book for tomato which provides guidance for describing a tomato variety, as published by Naktuinbow (version 1, December 2010). The calibration book is based on the CPVO (Community Plant Variety Protection Office) Protocol CPVO-TP/044/3 and UPOV TG/44/10.
“RHS” refers to the Royal Horticultural Society (RHS) which publishes an official botanical color chart quantitatively identifying colors according to a defined numbering system. The chart may be purchased from Royal Horticulture Society Enterprise Ltd RHS Garden; Wisley, Woking; Surrey GU236QB, UK, e.g., the RHS color chart 2007.
“Reference Variety for NUN 09225 TOF” refers herein to variety NUN 09085 TOF, a variety from Nunhems B. V., which has been planted in a trial together with NUN 09225 TOF. The characteristics of tomato variety NUN 09225 TOF are compared with the characteristics of the Reference Variety as shown in Table 1. The disease resistances of tomato variety NUN 09225 TOF and the Reference Variety are shown in Table 2. The distinguishing characteristics between tomato variety NUN 09225 TOF and the Reference Variety are shown in Table 3.
A plant having “all the physiological and morphological characteristics” of a referred-to-plant means a plant showing the physiological and morphological characteristics of the referred-to-plant when grown under the same environmental conditions, preferably in the same experiment; the referred-to-plant can be a plant from which it was derived, e.g., the progenitor plant, the parent, the recurrent parent, the plant used for tissue- or cell culture, etc. A physiological or morphological characteristic can be a numerical characteristic or a non-numerical characteristic. In one aspect, a plant has “all but one, two or three of the physiological and morphological characteristics” of a referred-to-plant, or “all the physiological and morphological characteristics” of Tables 1 and 2 or “all or all but one, two or three of the physiological and morphological characteristics” of Tables 1 and 2.
The physiological and/or morphological characteristics mentioned above are commonly evaluated at significance levels of 1%, 5% or 10% if they are numerical (quantitative), or for having an identical degree (or type) if not numerical (not quantitative), if measured under the same environmental conditions. For example, a progeny plant or a Single Locus Converted plant or a mutated plant of variety NUN 09225 TOF may have one or more (or all) of the essential physiological and/or morphological characteristics of said variety listed in Tables 1 and 2, as determined at the 5% significance level (i.e., p<0.05), when grown under the same environmental conditions.
“Distinguishing characteristics” or “distinguishing morphological and/or physiological characteristics” refers herein to the characteristics which distinguish (i.e., are different) between the new variety and other tomato varieties, such as the Reference Variety, when grown under the same environmental conditions. The distinguishing characteristics between tomato variety NUN 09225 TOF and Reference Variety are described in Table 3. When comparing tomato variety NUN 09225 TOF with different varieties, the distinguishing characteristics will be different. In one aspect, the distinguishing characteristics may therefore include at least one, two, three or more (or all) of the characteristics listed in Tables 1 and 2. All numerical distinguishing characteristics are statistically significantly different at p<0.05 between tomato variety NUN 09225 TOF and the other variety (e.g., Reference Variety).
Tomato variety NUN 09225 TOF has the following distinguishing characteristics when compared to the Reference Variety as shown in Table 3: 1 horizontal leaf attitude; 2) smaller size of leaflets; 3) darker intensity of green color of mature leaf; 4) shorter peduncle length of mature leaf; 5) no green shoulder; 6) oblate mature fruit shape at longitudinal section; 7) stronger ribbing at peduncle end; 8) stronger depression at peduncle end; 9) flat shape at blossom end; 10) larger size of core in cross-section; 11) thicker pericarp; 12) glossier skin; 13) colorless epidermis; and 14) medium shell life, when grown under the same environmental conditions.
Thus, a tomato plant “comprising the distinguishing characteristics of NUN 09225 TOF” (such as a progeny plant) refers herein to a plant which does not differ significantly from said variety in the distinguishing characteristics above. Therefore, in one aspect, the disclosure provides a plant that does not differ significantly from tomato variety NUN 09225 TOF in the distinguishing characteristics above.
Similarity and differences between two different plant lines or varieties can be determined by comparing the number of morphological and/or physiological characteristics (e.g., the characteristics as listed in Tables 1 and 2) that are the same (i.e., statistically not significantly different) or that are different (i.e., statistically significantly different) between the two plant lines or varieties when grown under the same environmental conditions. A numerical characteristic is considered to be “the same” when the value for a numeric characteristic is not significantly different at the 1% (p<0.01) or 5% (p<0.05) significance level, using one way analysis of variance (ANOVA), a standard method known to the skilled person. Non-numerical or “degree” or “type” characteristic is considered “the same” when the values have the same “degree” or “type” when scored using USDA and/or UPOV descriptors, if the plants are grown under the same environmental conditions.
“Variety” or “cultivar” means a plant grouping within a single botanical taxon of the lowest rank.
A “plant line” is, for example, a breeding line which can be used to develop one or more varieties. A breeding line is typically highly homozygous.
“Harvested seeds” refer to seeds harvested from a line or variety, e.g., produced after self-fertilization or cross-fertilization and collected.
“Hybrid variety” or “F1 hybrid” refers to the seeds harvested from crossing two inbred (nearly homozygous) parental lines. For example, the female parent is pollinated with pollen of the male parent to produce hybrid (F1) seeds on the female parent.
“Locus” (plural loci) refers to the specific location, place or site of a DNA sequence on a chromosome, where, for example, a gene or genetic marker is found. A locus may confer a specific trait.
“Allele” refers to one or more alternative forms of a gene locus. All of these loci relate to one trait. Sometimes, different alleles can result in different observable phenotypic traits, such as different pigmentation. However, many variations at the genetic level result in little or no observable variation. If a multicellular organism has two sets of chromosomes, i.e., diploid, these chromosomes are referred to as homologous chromosomes, i.e., diploid. Diploid organisms have one copy of each gene (and therefore one allele) on each chromosome. If both alleles are the same, they are homozygotes. If the alleles are different, they are heterozygotes.
“Genotype” refers to the genetic composition of a cell or organism.
“Phenotype” refers to the detectable characteristic of a plant, cell, or organism, which characteristics are the manifestation of gene expression.
“Haploid” refers to a cell or organism having one set of the two sets of chromosomes in a diploid.
“Diploid” refers to a plant, a vegetative plant part(s), or seed which a diploid plant can be grown, having two sets of chromosomes, designated herein as 2n.
“Triploid” refers to a plant, a vegetative plant part(s), or seed which a diploid plant can be grown, having three sets of chromosomes, designated herein as 3n.
“Tetraploid” refers to a plant, a vegetative plant part(s), or seed which a diploid plant can be grown, having four sets of chromosomes, designated herein as 4n.
“Scion” refers to a part of the plant attached to the rootstock. This plant is selected for its stems, leaves, flowers, or fruits. The scion contains the desired genes to be duplicated in future production by the stock/scion plant and may produce the desired tomato fruit.
“Rootstock” or “stock” refers to the plant selected for its roots, in particular for the resistance of the roots to diseases or stress (e.g., heat, cold, salinity etc.). Normally the quality of the fruit of the plant providing the rootstock is less important.
“Stock/scion” or grafted plant refers to a tomato plant comprising a rootstock from one plant grafted to a scion from another plant.
“Grafting” refers to the method of joining of (genetically) different plant parts, especially scions and rootstocks, together so that they grow as a single plant. A grafted seedling or a grafted plant is a seedling or plant (produced by grafting) consisting of such different plant parts and which grows as one plant.
The term “traditional breeding techniques” encompasses herein crossing, selfing, selection, doubled haploid production, embryo rescue, protoplast fusion, marker assisted selection, mutation breeding, etc. as known to the breeder (e.g., methods other than genetic modification/transformation/transgenic methods), by which, for example, a genetically heritable trait can be transferred from one tomato line or variety to another.
“Tissue culture” or “cell culture” refers to a composition comprising isolated cells of the same or a different type or a collection of such cells organized into parts of a plant. Tissue culture of various tissues of tomato and regeneration of plants therefrom is well known and widely published (see, e.g., Bhatia et al. (2004), Plant Cell, Tissue and Organ Culture 78: 1-21). Similarly, methods of preparing cell cultures are known in the art.
“Regeneration” refers to the development of a plant from cell culture or tissue culture or vegetative propagation.
“Vegetative propagation,” “vegetative reproduction,” or “clonal propagation” are used interchangeably herein and mean a method of taking a part of a plant and allowing that plant part to form at least roots, and also refer to the plant or plantlet obtained by that method. Optionally, the vegetative propagation is grown into a mature plant. The skilled person is aware of what plant parts are suitable for use in the method.
“Selfing” refers to self-pollination of a plant, i.e., the transfer of pollen from the anther to the stigma of the same plant.
“Crossing” refers to the mating of two parent plants. The term encompasses “cross-pollination” and “selfing”.
“Cross-pollination” refers to the fertilization by the union of two gametes from different plants.
“Backcrossing” is a traditional breeding technique used to introduce a trait into a plant line or variety. The plant containing the trait is called the donor plant and the plant into which the trait is transferred is called the recurrent parent. An initial cross is made between the donor parent and the recurrent parent to produce a progeny plant. Progeny plants which have the trait are then crossed to the recurrent parent. After several generations of backcrossing and/or selfing the recurrent parent comprises the trait of the donor. The plant generated in this way may be referred to as a “single trait converted plant”. The technique can also be used on a parental line of a hybrid.
“Progeny” as used herein refers to a plant obtained from a plant designated NUN 09225 TOF. A progeny may be obtained by regeneration of cell culture or tissue culture or parts of a plant of said variety or selfing of a plant of said variety or by producing seeds of a plant of said variety. In further aspects, progeny may also encompass plants obtained from crossing of at least one plant of said variety with another tomato plant of the same variety or another variety or (breeding) line, or with wild tomato plants. A progeny may comprise a mutation or a transgene. A “first generation progeny” or is the progeny directly derived from, obtained from, obtainable from or derivable from the parent plant by, e.g., traditional breeding methods (selfing and/or cross-pollinating) or regeneration (optimally combined with transformation or mutation). Thus, a plant of variety NUN 09225 TOF is the male parent, the female parent or both of a first generation progeny of that variety. Progeny may have all the physiological and morphological characteristics of variety NUN 09225 TOF when grown under the same environmental conditions. Using common breeding methods such as backcrossing or recurrent selection, mutation or transformation, one or more specific characteristics may be introduced into said variety, to provide a plant comprising all but 1, 2, or 3 or more of the morphological and physiological characteristics of variety NUN 09225 TOF (as listed in Tables 1 and 2).
The terms “gene converted” or “conversion plant” or “single locus converted plant” in this context refer to tomato plants which are developed by traditional breeding techniques e.g., backcrossing, or via genetic engineering or through mutation breeding, wherein essentially all of the desired morphological and physiological characteristics of the parent variety or line are recovered, in addition to the one or more genes transferred into the parent via e.g., the backcrossing technique (optionally including reverse breeding or reverse synthesis of breeding lines). It is understood that not only the addition of a further characteristic (e.g., addition of gene conferring a further characteristic, such as a disease resistance gene), but also the replacement/modification of an existing characteristic by a different characteristic is encompassed herein (e.g., mutant allele of a gene can modify the phenotype of a characteristic).
Likewise, a “Single Locus Converted (Conversion) Plant” refers to plants developed by plant breeding techniques comprising or consisting of mutation and/or by genetic transformation and/or by traditional breeding techniques, such as backcrossing, wherein essentially all of the desired morphological and physiological characteristics of a tomato variety are recovered in addition to the characteristics of the single locus having been transferred into the variety via the above mentioned technique. In case of a hybrid, the gene may be introduced in the male or female parental line.
“Transgene” or “chimeric gene” refers to a genetic locus comprising a DNA sequence which has been introduced into the genome of the plant by transformation. A plant comprising a transgene stably integrated into its genome is referred to as “transgenic plant.”
As used herein, the terms “resistance” and “tolerance” are used interchangeably to describe plants that show no symptoms or significantly reduced symptoms to a specified biotic pest, pathogen, abiotic influence or environmental condition compared to a susceptible plant. These terms are optionally also used to describe plants showing some symptoms but that are still able to produce marketable product with an acceptable yield.
“Average” refers herein to the arithmetic mean.
The term “mean” refers to the arithmetic mean of several measurements. The skilled person understands that the appearance of a plant depends to some extent on the growing conditions of said plant. The mean, if not indicated otherwise within this application, refers to the arithmetic mean of measurements on at least 10 different, randomly selected plants of a variety or line.

In a different aspect, the progeny plant comprises all of the physiological and morphological characteristic of tomato variety NUN 09225 TOF of Tables 1 and 2.
The disclosure also provides a method for developing a tomato plant in a tomato breeding program, using a tomato plant described herein, or its parts as a source of plant breeding material. Suitable plant breeding techniques are recurrent selection, backcrossing, pedigree breeding, mass selection, mutation breeding, and/or genetic marker enhanced selection. In one aspect, the method comprises crossing tomato variety NUN 09225 TOF or progeny of said variety, or a plant comprising all but 1, 2, or 3 or more of the morphological and physiological characteristics of tomato variety NUN 09225 TOF (e.g., as listed in Tables 1 and 2), with a different tomato plant, and wherein one or more offspring of the crossing are subject to one or more plant breeding techniques: recurrent selection, backcrossing, pedigree breeding, mass selection, mutation breeding and genetic marker enhanced selection (see, e.g., Vidaysky and Czosnek, (1998) Phytopathology 88(9): 910-4). For breeding methods in general, see, e.g., Principles of Plant Genetics and Breeding, 2007, George Acquaah, Blackwell Publishing, ISBN-13: 978-1-4051-3646-4.
In one aspect, pedigree selection is used as a breeding method for developing a tomato variety. Pedigree selection is also known as the “Vilmorin System of Selection,” see, e.g., Allard, John Wiley & Sons, Inc., 1999, pp. 64-67. In general, selection is first practiced among F2 plants. In the next season, the most desirable F3 lines are first identified, then desirable F3 plants within each line are selected. The following season and in all subsequent generations of inbreeding, the most desirable families are identified first, then desirable lines within the selected families are chosen. A family refers to lines that were derived from plants selected from the same progeny from the preceding generation.
Thus, progeny in connection with pedigree selection are either the generation (seeds) produced from the first cross (F1) or selfing (S1), or any further generation produced by crossing and/or selfing (F2, F3, etc.) and/or backcrossing (BC1, BC2, etc.) one or more selected plants of the F1 and/or S1 and/or BC1 generation (or plants of any further generation, e.g., F2) with another tomato plant (and/or with a wild relative of tomato). Progeny may have all the physiological and morphological characteristics of tomato variety NUN 09225 TOF when grown under the same environmental conditions and/or progeny may have (be selected for having) one or more of the distinguishing characteristics of tomato variety NUN 09225 TOF.
In yet a further aspect, the disclosure provides for a method of producing a new tomato plant. The method comprises crossing tomato variety NUN 09225 TOF, or a plant comprising all but 1, 2, or 3 of the morphological and physiological characteristics of tomato variety NUN 09225 TOF (as listed in Tables 1 and 2), or a progeny plant thereof, either as male or as female parent, with a second tomato plant (or a wild relative of tomato) one or more times, and/or selfing a tomato plant of variety NUN 09225 TOF, or a progeny plant thereof, one or more times, and selecting progeny from said crossing and/or selfing. The second tomato plant may, for example, be a line or variety of the species Solanum Lycopersicon, S. chilense, S. habrochaites, S. penelli, S. peruvianum, S. pimpinellifolium or other Solanum species.
In a further aspect, tomato variety NUN 09225 TOF is used in crosses with other, different, tomato varieties to produce first generation (F1) tomato hybrid seeds and plants with superior characteristics. In a particular aspect, the disclosure provides a tomato seed and a plant produced by crossing a first parent tomato plant with a second parent tomato plant, wherein at least one of the first or second parent tomato plant is tomato variety NUN 09225 TOF. In another aspect, the tomato seed and plant produced are the first filial generation (F1) tomato seed and plants produced by crossing the plant of tomato variety NUN 09225 TOF with another tomato plant.
The morphological and physiological characteristics (and the distinguishing characteristics) of tomato variety NUN 09225 TOF are provided in Tables 1 and 2, as collected in a trial according to USDA and/or UPOV standards. Encompassed herein is also a plant obtainable from tomato variety NUN 09225 TOF (e.g., by selfing and/or crossing and/or backcrossing with said variety and/or progeny of said variety) comprising all or all but one, two or three of the physiological and morphological characteristics of tomato variety NUN 09225 TOF listed in Tables 1 and 2 (as determined at the 5% significance level for numerical characteristics or identical for non-numerical characteristics) when grown under the same environmental conditions and/or comprising one or more (or all; or all except one, two or three) characteristics when grown under the same environmental conditions. The morphological and/or physiological characteristics may vary somewhat with variation in the environment (such as temperature, light intensity, day length, humidity, soil, fertilizer use), which is why a comparison under the same environmental conditions is preferred. Colors can best be measured using the Royal Horticultural Society (RHS) Chart.
In another aspect, the disclosure provides a method of producing a plant derived from a tomato variety NUN 09225 TOF, comprising crossing a plant of variety NUN 09225 TOF either as a male or female parent with a second plant or selfing tomato variety NUN 09225 TOF or vegetative reproduction of tomato variety NUN 09225 TOF and collecting seeds from said crossing or selfing or regenerating a whole plant from the vegetable cell-or tissue culture. Also provided are seeds and/or plants obtained by this method. All plants produced using tomato variety NUN 09225 TOF as a parent are within the scope of the disclosure including plant parts derived from tomato variety NUN 09225 TOF.
In further aspects, the method comprises growing a progeny plant of a subsequent generation and crossing the progeny plant of a subsequent generation with itself or a second plant and repeating the steps for additional 3-10 generations to produce a plant derived from tomato variety NUN 09225 TOF. The plant derived from tomato variety NUN 09225 TOF may be an inbred line and the aforementioned repeating crossing steps may be defined as comprising sufficient inbreeding to produce the inbred line. By selecting plants having one or more desirable traits of the line as well as potentially other selected traits.
The disclosure provides for methods of producing plants which retain all the morphological and physiological characteristics of a plant described herein. The disclosure also provides for methods of producing a plant comprising all but 1, 2, or 3 or more of the morphological and physiological characteristics of tomato variety NUN 09225 TOF (e.g., as listed in Tables 1 and 2), but which are still genetically closely related to said variety. The relatedness can, for example, be determined by fingerprinting techniques (e.g., making use of isozyme markers and/or molecular markers such as Single-nucleotide polymorphism (SNP) markers, amplified fragment length polymorphism (AFLP) markers, microsatellites, minisatellites, Random Amplified Polymorphic DNA (RAPD) markers, restriction fragment length polymorphism (RFLP) markers and others). A plant is “closely related” to tomato variety NUN 09225 TOF if its DNA fingerprint is at least 80%, 90%, 95% or 98% identical to the fingerprint of that variety. In a particular aspect, AFLP markers are used for DNA fingerprinting (see, e.g., Vos et al. 1995, Nucleic Acid Research 23: 4407-4414). A closely related plant may have a Jaccard's Similarity index of at least about 0.8, preferably at least about 0.9, 0.95, 0.98 or more (see, e.g., Sharifova, S., et. al., (2013), Journal of Hort. Research, 21(1):83-89; Ince et al., (2010), Biochem. Genet. 48:83-95; Parvathaneni et al., (2011), J. Crop Sci. Biotech, 14 (1): 39-43; Pisanu, et. al., (2004), Acta Hort. 660, 83-89). The disclosure also provides a plant and a variety obtained or selected by applying these methods on tomato variety NUN 09225 TOF. Such a plant may be produced by crossing and/or selfing, or alternatively, a plant may simply be identified and selected amongst plants of said variety, or progeny of said variety, e.g. by identifying a variant within tomato variety NUN 09225 TOF or within progeny of said variety (e.g., produced by selfing) which variant differs from the variety described herein in one, two or three of the morphological and/or physiological characteristics (e.g., in one, two or three distinguishing characteristics), e.g. those listed in Tables 1 and 2. In one aspect, the disclosure provides a tomato plant having a Jaccard's Similarity index with tomato variety NUN 09225 TOF of at least 0.8, e.g. at least 0.85, 0.9, 0.95, 0.98 or even at least 0.99.
In some aspects, the disclosure provides a tomato plant comprising genomic DNA having at least 95%, 96%, 97%, 98% or 99% sequence identity compared to the genomic DNA sequence of a plant of variety NUN 09225 TOF as deposited under Accession Number NCIMB ______. In some aspects, the tomato plant further comprises all or all but 1, 2, or 3 of the morphological and physiological characteristics of tomato variety NUN 09225 TOF (e.g., as listed in Tables 1 and 2). In other aspects, the tomato plant is a hybrid or other derived from a seed or plant of variety NUN 09225 TOF. In other aspects, the tomato plant comprises the distinguishing characteristics of tomato variety NUN 09225 TOF.
For the purpose of this disclosure, the “sequence identity” of nucleotide sequences, expressed as a percentage, refers to the number of positions in the two optimally aligned sequences which have identical residues (×100) divided by the number of positions compared. A gap, i.e., a position in the pairwise alignment where a residue is present in one sequence but not in the other, is regarded as a position with non-identical residues. A pairwise global sequence alignment of two nucleotide sequences is found by aligning the two sequences over the entire length according to the Needleman and Wunsch global alignment algorithm described in Needleman and Wunsch, 1970, J. Mol. Biol. 48(3):443-53). A full implementation of the Needleman-Wunsch global alignment algorithm is found in the needle program in The European Molecular Biology Open Software Suite (see, e.g., EMBOSS, Rice et al., Trends in Genetics June 2000, vol. 16, No. 6. pp. 276-277).
In one aspect, a plant of variety NUN 09225 TOF may also be mutated (by e.g., irradiation, chemical mutagenesis, heat treatment, etc.) and mutated seeds or plants may be selected in order to change one or more characteristics of said variety. Methods such as TILLING (Targeting Induced Local Lesions in Genomes) may be applied to tomato populations in order to identify mutants.
Similarly, tomato variety NUN 09225 TOF may be transformed and regenerated, whereby one or more chimeric genes are introduced into the variety or into a plant comprising all but 1, 2, 3, or more of the morphological and physiological characteristics (e.g., as listed in Tables 1 and 2). Many useful traits can be introduced into tomato variety NUN 09225 TOF by e.g., crossing a tomato variety NUN 09225 TOF with a transgenic tomato plant comprising a desired transgene, as well as by directly introducing a transgene into tomato variety NUN 09225 TOF by genetic transformation techniques.
Any pest or disease resistance genes may be introduced into a plant of tomato variety NUN 09225 TOF, progeny of said variety or into a plant comprising all but 1, 2, or 3 or more of the morphological and physiological characteristics of tomato variety NUN 09225 TOF (e.g., as listed in Tables 1 and 2). Resistance to one or more of the following diseases or pests may be introduced into the plant described herein: Colorado potato beetle, Southern root knot nematode, Spider mites, Sugarfly beet army worm, Tobacco flea beetle, Tomato hornworm, Tomato fruitworm, Whitefly, Bacterial canker, Bacterial soft rot, Bacterial speck, Bacterial wilt (Pseudomonas syringae pv. Tomato), Bacterial, Anthracnose (Gloeosporium piperatum), Brown rot or corky root (Pyrenochaeta lycopersici), Alternaria, Fusarium wilt (F. oxysporum races), Gray leaf spot (Stemphylium spp), Late blight (Phytophthora infestans races), and Leaf mold (Cladosporium fulvum races), Nematode (Meloidogyne spp.), Verticillium Wilt (Verticillium dahliae), Ralstonia solanacearum (Rs), Leveillula Taurica (Lt), and/or Oidium neolycopersici (On). Other resistance genes, against pathogenic viruses (e.g., Tomato Mosaic Virus (ToMV), Curly TOF Virus, Tomato Mottle Virus, Potato Y Virus, Blotchey Ripening, Tobacco Etch Virus, the various Tobacco Mosaic Virus races, Concentric cracking, Tomato Spotted Wilt Virus (TSWV), Tomato Yellow Leaf Curl Virus (TYLCV), Gold Fleck, Tomato Torrado Virus (ToTV)), fungi, bacteria, nematodes, insects or other pests may also be introduced.
Genetic transformation may, therefore, be used to insert a selected transgene into the tomato plants of the disclosure described herein or may, alternatively, be used for the preparation of transgenic tomato plants which can be used as a source of the transgene(s), which can be introduced into tomato variety NUN 09225 TOF by e.g., backcrossing. A genetic trait which has been engineered into the genome of a particular tomato plant may then be moved into the genome of another tomato plant (e.g., another variety) using traditional breeding techniques which are well-known in the art. For example, backcrossing is commonly used to move a transgene from a transformed tomato variety into an already developed tomato variety and the resulting backcross conversion plant will then comprise the transgene(s).
Any DNA sequences, whether from a different species or from the same species, which are inserted into the genome using transformation, are referred to herein collectively as “transgenes.” A “transgene” also encompasses antisense, or sense and antisense sequences capable of gene silencing. Thus, the disclosure also relates to transgenic plants of tomato variety NUN 09225 TOF. In some aspects, a transgenic plant of tomato variety NUN 09225 TOF may contain at least one transgene but could also contain at least 1, 2, 3, 4, or more transgenes.
Plant transformation involves the construction of an expression vector which will function in plant cells. Such a vector comprises DNA comprising a gene under control of, or operatively linked to a regulatory element active in plant cells (e.g., promoter). The expression vector may contain one or more such operably linked gene/regulatory element combinations. The vector may be in the form of a plasmid and can be used alone or in combination with other plasmids to provide transformed tomato plants using transformation methods to incorporate transgenes into the genetic material of the tomato plant(s). Transformation can be carried out using standard methods, such as Agrobacterium tumefaciens mediated transformation, electroporation, biolistics particle delivery system, or microprojectile bombardment, followed by selection of the transformed cells and regeneration into plants.
Plants can also be genetically engineered, modified, or manipulated to express various phenotypes of horticultural interest. Through the transformation of tomato, the expression of genes can be altered to enhance disease resistance, insect resistance, herbicide resistance, stress tolerance, horticultural quality, and other traits. Transformation can also be used to insert DNA sequences which control or help control male sterility or fertility restoration. DNA sequences native to tomato as well as non-native DNA sequences can be transformed into tomato and used to alter levels of native or non-native proteins. Various promoters, targeting sequences, enhancing sequences, and other DNA sequences can be inserted into the genome for the purpose of altering the expression of proteins. Reduction of the specific activity of specific genes (also known as gene silencing or gene suppression) is desirable for several aspects of genetic engineering in plants.
Genome editing is another method recently developed to genetically engineer plants. Specific modification of chromosomal loci or targeted mutation can be done through sequence-specific nucleases (SSNs) by introducing a targeted DNA double strand break in the locus to be altered. Examples of SSNs that have been applied to plants are: finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), engineered homing endonucleases or meganucleases, and clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9), see, e.g., Songstad, et. al., Critical Reviews in Plant Sciences, 2017, 36:1, 1-23.
Thus, the disclosure also provides a method of producing a tomato plant having a desired trait comprising mutating the plant or plant part of variety NUN 09225 TOF and selecting a plant comprising the desired trait, wherein the mutated plant retains all or all but one of the physiological and morphological characteristics of variety NUN 09225 TOF, optionally as described in Tables 1 and 2, and contains the desired trait and wherein a representative sample of seed of variety NUN 09225 TOF is deposited under Accession Number NCIMB ______.

The disclosure also provides methods for determining the identity of parental lines of plants described herein, in particular the identity of the female line. US 2015/0126380, which is hereby incorporated by reference, relates to a non-destructive method for analyzing maternal DNA of a seed. In this method, the DNA is dislodged from the seed coat surface and can be used to collect information on the genome of the maternal parent of the seed. This method for analyzing maternal DNA of a seed comprises contacting a seed with a fluid to dislodge DNA from the seed coat surface, and analyzing the DNA thus dislodged from the seed coat surface using methods known in the art. The skilled person is thus able to determine whether a seed has grown on a plant of variety NUN 09225 TOF or is a progeny of said variety, because the seed coat of the seed is a maternal tissue genetically identical to tomato variety NUN 09225 TOF. In one aspect, the present disclosure relates to a seed coat comprising maternal tissue of tomato variety NUN 09225 TOF. In another aspect, the disclosure relates to a tomato seed comprising a maternal tissue of tomato variety NUN 09225 TOF.

Using methods known in the art such as “reverse synthesis of breeding lines” or “reverse breeding,” it is possible to produce parental lines for a hybrid plant such as tomato variety NUN 09225 TOF. A skilled person can take any individual heterozygous plant (called a “phenotypically superior plant” in Example 2 of US 2015/0245570, which is hereby incorporated by reference in its entirety; tomato variety NUN 09225 TOF is such plant) and generate a combination of parental lines (reverse breeding parental lines) that, when crossed, produce the variety NUN 09225 TOF. It is not necessary that the reverse breeding parental lines are identical to the original parental lines. Such new breeding methods are based on the segregation of individual alleles in the spores produced by a desired plant and/or in the progeny derived from the self-pollination of that desired plant, and on the subsequent identification of suitable progeny plants in one generation, or in a limited number of inbred cycles. Such a method is known from US 2015/0245570 or from Wijnker et al., Nature Protocols Volume: 9, Pages: 761-772 (2014) DOI: doi:10.1038/nprot.2014.049. Thus, the disclosure provides a method for producing parental lines for a hybrid organism (e.g., tomato variety NUN 09225 TOF), comprising in one aspect: a) defining a set of genetic markers present in a heterozygous form (H) in a partially heterozygous starting organism; b) producing doubled haploid lines from spores of the starting organism; c) genetically characterizing the doubled haploid lines thus obtained for the said set of genetic markers to determine whether they are present in a first homozygous form (A) or in a second homozygous form (B); and d) selecting at least one pair of doubled haploid lines that have complementary alleles for at least a subset of the genetic markers, wherein each member of the pair is suitable as a parental line for the hybrid organism.

- b) producing at least one further generation from the starting organism by self-pollination (e.g., F2 or F3 generation);
- c) selecting at least one pair of progeny organisms in which at least one genetic marker from the set is present in a complementary homozygous form (B vs. A, or A vs. B); and
- d) optionally repeating steps b) and c) until at least one pair of progeny organisms that have complementary alleles for at least a subset of the genetic markers has been selected as parental lines for a hybrid.

Thus, in one aspect, the disclosure relates to a method of producing a combination of parental lines of a plant of variety NUN 09225 TOF, comprising making doubled haploid cells from haploid cells or seed of that plant; and optionally crossing these parental lines to produce and collecting seeds.

Doubled haploid lines generated as described herein can be used in such a method.
The disclosure also provides a combination of parental lines which, when crossed, produce a seed or plant having all physiological and/or morphological characteristics of tomato variety NUN 09225 TOF but one, two or three which are different (when grown under the same environmental conditions), as well as a seed or plant having all physiological and/or morphological characteristics of tomato variety NUN 09225 TOF but one, two or three which are different (when the characteristics are determined at the 5% significance level for plants grown under the same conditions).

Development of Tomato Variety NUN 09225 TOF

The hybrid variety NUN 09225 TOF was developed from a male and female proprietary inbred line of Nunhems, selected mainly for its big round size and intense trait (full flesh). The female and male parents were crossed to produce hybrid (F1) seeds of tomato variety NUN 09225 TOF. The seeds of tomato variety NUN 09225 TOF can be grown to produce hybrid plants and parts thereof (e.g., tomato fruit). The hybrid variety NUN 09225 TOF can be propagated by seeds or vegetatively.
The hybrid variety is uniform and genetically stable. This has been established through evaluation of horticultural characteristics. Several hybrid seed production events resulted in no observable deviation in genetic stability. Coupled with the confirmation of genetic stability of the female and male parents the Applicant has concluded that tomato variety NUN 09225 TOF is uniform and stable.
