Abstract

A new and distinct seedless mandarin named ‘Late Seedless Mandarin’ is characterized by late fruit production in April through to late March in the citrus areas of Sicily, Italy and Riverside, Calif. The tree has high yields and bears from year three onwards. It is further characterized by being a triploid and genetically seedless. The seedless fruit is well sized, has a typical mandarin shape (round, flattened) and has acceptable rind thickness with a smooth texture. The fruit has good acid/sugar ratios, has acceptable shipping characteristics, internal and external color is excellent at harvest, and eating quality is excellent. The fruit has an average juice content of about 45% to about 60% at harvest.

Description

(Citrus reticulata hybrid)
BACKGROUND OF THE NEW VARIETY
The present invention refers to a new late harvesting variety of triploid mandarin which will hereinafter be denominated as the ‘Late Seedless Mandarin’ tree. The ‘Late Seedless Mandarin’ tree produces commercially seedless mandarin fruit, bearing in late March through to May in the citrus areas of Sicily, Italy. The ‘Late Seedless Mandarin’ trees are triploid (three sets of chromosomes). The trees bear from year three and have consistent year-to-year bearing habits. The fruit has acceptable rind thickness, acid-sugar ratios and color, and has an average juice content of 45% to about 60% at harvest.
In the development of new commercial fruit varieties, specific characteristics provide a premium on those fruit varieties that mature late or late in the growing season. For a new fruit variety to be a commercial success the fruit must be of good size, good color, and also have good holding/storage characteristics, advantageous harvest times and shipping characteristics. In addition, the date of maturing must be different from other similar fruit. This new invention meets all of the aforementioned criteria and therefore would be of commercial appeal to the consumer.
The ‘Late Seedless Mandarin’ variety is a triploid sexual hybrid. Polyploidy in citrus is well known (pgs. 191-193, Spiegel-Roy & Goldschmidt, 1966). Citrus and related genera are typically diploidic and have two sets of 9 chromosomes (2n=18). Triploids, tetraploids and hexaploids exist naturally but occur in low percentages in the population. Citrus triploids are cytologically recognizable by the presence of an additional set of chromosomes. In some cases, triploids are also morphologically recognizable.
ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY
The invention (variety) comprises a new and distinct variety of a seedless mandarin plant named ‘Late Seedless Mandarin’, discovered by the inventors in Azienda Palazzelli Lentini (SR), Sicily, Italy in 1998. The new cultivar is a triploid (3n) selection from sexual crosses made among a tetraploid (pollen bearing) male parent; a ‘Avava’ Mandarin (4n) (unpatented) and a diploid (seed bearing) female parent [‘Fortune’ Mandarin (2n) (unpatented)] and referred to as ‘Late Seedless Mandarin’. The new cultivar was subsequently asexually reproduced by the inventors in 2000 by in vitro propagation and subsequent bud grafting onto ‘Sour Orange’ rootstock (200 trees in total). The resulting trees were experimentally evaluated. The resulting tree growth was strong with no bud union abnormalities being noted on the ‘Sour Orange’ rootstock. An additional 10 trees were asexually reproduced by the inventors in 2004 by bud grafting onto ‘Sour Orange’ rootstock. An additional 10 trees were asexually reproduced by the inventors in 2004 by bud grafting onto ‘Sour Orange’ rootstock and grown in Riverside, Calif. The inventors carefully compared all of the asexually reproduced trees with the parent tree, including the fruit, and found, thus far, that they are identical in all respects. The trees under evaluation are free from all known viruses and viroids including Tristeza, Exocortis, Xyloporosis, Stubborn, Citrus Greening disease, Impetratura and Psorosis.
SUMMARY OF THE NEW VARIETY
The ‘Late Seedless Mandarin’ is particularly characterized by being a triploid, genetically (and hence commercially) seedless, of good fruit size, precocious with stable year-to-year high yields and a late bearing variety (late March to May) in northern hemisphere citrus-bearing regions. The internal fruit quality is excellent.

The above description of this new variety of mandarin is based on the growing conditions prevalent in Sicily, Italy and in Riverside, Calif. Variations of the usual magnitude, such as differences in maturity date and production, may be due to cultural practices, including irrigation, fertilization, pruning, fruit thinning and primary climate changes as well as soil conditions.
