Description
Botanical classification: Citrus hybrid.
Varietal denomination: ‘FIRST CANADIAN’.
This application is related to a Canadian plant breeders' rights application filed on Mar. 7, 2011, application No. 11-7213. There have been no offers for sale anywhere in the world prior to the effective filing date of this Application and no accessibility to one of ordinary skill in the art could have been derived from the printed plant breeder's rights documents.
The present invention relates to a new and distinct cultivar of Citrus plant, botanically of hybrid origin and known as Citrus ‘First Canadian’ and will be referred to hereafter by its cultivar name, ‘First Canadian’. The new cultivar represents a new dwarf lemon plant that is grown for use in homes under low light conditions.
The new cultivar was derived from an ongoing controlled breeding program conducted by the Inventor in Saskatoon, Saskatchewan, that commenced in 1981. The overall purpose of the breeding program is the creation of a new type of dwarf lemon trees and other hybrid Citrus trees that exhibit the fruit quality of commercial varieties that are also Low Light Tolerant [LLT] and can be grown in homes on indoor windowsills in small 6-inch containers with only natural available light.
The new cultivar arose from a cross made in April of 1991 between an unnamed and unpatented proprietary plant from the Inventor's breeding program designated as “CLX-1” (Citrus medica x Citrus limonia) as the female parent and Citrus x meyeri (unpatented) as the male parent. ‘First Canadian’ was selected as a single unique plant amongst the seedlings from the above cross in October 2010.
Asexual propagation of the new cultivar was first accomplished by stem cuttings in Saskatoon Canada, by the Inventor in October of 2010. Asexual propagation by stem cuttings has been determined that the characteristics of this cultivar are stable and are true to type in successive reproductions.
The following traits have been repeatedly observed and represent the unique characteristics of the new cultivar of Citrus. Trials were conducted over many years in Saskatoon, Saskatchewan, Canada.
-
- 1. ‘First Canadian’ exhibits low light tolerance when grown in a home windowsill without supplemental lighting in small containers.
- 2. ‘First Canadian’ exhibits fruit that is similar in quality to high quality commercial Lemons and is essentially seedless (an occasionally seed may arise as the plant is apomictic).
- 3. ‘First Canadian’ exhibits fruit with a skin thickness of 5 to 6 mm.
- 4. ‘First Canadian’ exhibits fruit with a Brix of 7° to 8° with a tart flavor.
- 5. ‘First Canadian’ exhibits a dwarf, bushy plant habit that is ideal for small container windowsill culture in homes in cold climates, and can be made into a bonsai tree.
- 6. ‘First Canadian’ exhibits good fruit production indoors in homes and commercial buildings where the atmospheric temperature is within 55 to 75° F. and the available light level is of typical of indoor spaces (75-200 μmol/m2/s).
- 7. ‘First Canadian’ exhibits the ability to grow well and produce an abundance of fruit in hydroculture (up to 36 fruits per year has been observed).
- 8. ‘First Canadian’ exhibits mature fruit with bright yellow skin and a conspicuous style and stigma.
- 9. ‘First Canadian’ exhibits dense flower clusters of 8 to 12 flowers resulting in up to 6 fruits per cluster.
- 10. ‘First Canadian’ exhibits multiple cycles of blooms and fruit set per year (up to 4 cycles).
The female parent of ‘First Canadian’, “CLX-1”, differs from ‘First Canadian’ in having fruit that is larger ellipsoid shape in size, blooms and fruits less frequently, and in having less flowers per cluster. The male parent of ‘First Canadian’, Citrus x meyeri, differs from ‘First Canadian’ in having fruit that is smaller in size, epicarp and juice vesicles that are more orange in color, juicier and sweeter with a thinner rind, and in having leaves that are ovate in shape and petioles that lack wings. In addition, Citrus x meyeri, fails to thrive when grown under low light conditions. ‘First Canadian’ is unique in its ability to grow and set fruit under low light conditions and the Inventor has not had success in growing any other available cultivars under the same conditions. ‘First Canadian’ can be compared to the Citrus cultivar ‘Ponderosa’ (not patented), however ‘Ponderosa’ is grown by home owners outdoors in subtropical climates. ‘Ponderosa’ differs in having fruit that is more ellipsoid in shape with a nipple present. The fruit is also 3-4 times larger with a rough skin and the tree matures to a much larger size and fails to thrive when grown under low light conditions.
The accompanying color photographs illustrate the distinguishing characteristics of the new cultivar ‘First Canadian’. The photographs in FIG. 1 and FIG. 2 were taken of plants (and plant parts) 27 years in age as grown in a container (12″ in length, 12″ in width, 20″ in height) in a greenhouse in Saskatoon, Saskatchewan, Canada. The photographs in FIG. 3 , FIG. 4 , and FIG. 5 were taken of plants (and plant parts) about 2 years in age as grown indoors on a home windowsill in small 6-inch containers in Grasswood, Saskatchewan, Canada.
The photograph in FIG. 1 provides a view of the dwarf habit of a 27 year-old plant of ‘First Canadian’.
The photograph in FIG. 2 provides a view of maturing fruit of ‘First Canadian’.
The photograph in FIG. 3 provides a view of a whole fruit and cut fruit of ‘First Canadian’.
The photograph in FIG. 4 provides a view of a hydroponically grown plant.
The photograph in FIG. 5 provides a view of an inflorescence.
The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Citrus.
The following is a detailed description of 1 to 2-year-old plants of the new cultivar as grown indoors under low light in containers in a greenhouse in Saskatoon, Saskatchewan, Canada. The phenotype has not been observed to be consistent when grown under constant indoor temperature, variable day length, natural reflected light intensity, and proper water and fertility levels. However, the phenotype of the new cultivar may vary with variations in environmental and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2015 Colour Chart of the Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
