Patent Grant
PP24948
Botanical name of the genus and species of the plant claimed: Citrus deliciosa Ten (ex C. reticulata Blanco).
Variety denomination: ‘HADASS’.
The present invention relates to a new and distinct variety of a mandarin tree, botanically known as Citrus deliciosa Ten. of the Rutaceae family, and hereinafter referred to by the variety denomination ‘HADASS’.
The new Citrus deliciosa Ten. variety is a product of a planned breeding program conducted by the inventors, Avraham Shaked, Michael Hamou and David Hesdai, at the Volcani Center, Bet Dagan, Israel. The objective of the breeding program was to develop a new late ripening, Citrus deliciosa Ten. variety with high internal quality.
The new Citrus deliciosa Ten. variety originated from a selection out of a seedling population, resulting from open pollination of the Citrus deliciosa Ten. designated ‘ELLENDALE’ (unpatented), made by the inventors in 1971 in the Volcani Center, Bet Dagan, Israel. The new Citrus deliciosa Ten. ‘HADASS’ was observed and selected by the inventors within this seedling population in a controlled environment in 1975 in the Volcani Center.
Asexual propagation of the new Citrus deliciosa Ten. variety by grafting onto ‘Troyer’ citrange—Citrus sinensis (L.) Osb.×Poncirus trifoliata L. (unpatented) was first performed in May 1975 in the Volcani Center, and has demonstrated that the combination of characteristics as herein disclosed for the new variety is firmly fixed and retained through successive generations of asexual propagation. The new variety propagates true-to-type.
The following traits have been repeatedly observed and are determined to be characteristics of ‘HADASS’ which, in combination, distinguish this mandarin tree as a new, unique and distinct variety:
In comparison to the parental variety, ‘ELLENDALE’ (unpatented), ‘HADASS’ differs primarily in the traits listed in Table 1.
Of the many commercial varieties known to the present inventors, the most similar to the new Citrus deliciosa Ten. ‘HADASS’ is Citrus deliciosa Ten. ‘MURCOTT’ (unpatented), which differs from the new mandarin ‘HADASS’ in the characteristics described in Table 2:
The accompanying photographs illustrate the overall appearance of the new Citrus deliciosa Ten. variety ‘HADASS’ showing the colors as true as is reasonably possible with colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed morphological description, which accurately describe the color of ‘HADASS’.
FIG. 1—Shows a flowering tree of ‘HADASS’.
FIG. 2—Shows a fruit-bearing tree of ‘HADASS’.
FIG. 3—Shows a typical leaf of ‘HADASS’.
FIG. 4—Shows typical mature fruit of ‘HADASS’.
FIG. 5—Shows typical mature fruit of ‘HADASS’ in cross section.
FIG. 6—Shows typical buds of ‘HADASS’.
FIG. 7—Shows typical flowers of ‘HADASS’.
The new Citrus deliciosa Ten. ‘HADASS’ has not been observed under all possible environmental conditions. The phenotype of the new variety may vary with variations in environment such as temperature, light intensity, day length, soil or pruning without any change in the genotype of the mandarin plant.
The aforementioned photographs, together with the following observations, measurements and values describe trees of ‘HADASS’ as grown in the orchard at the Volcani Center, under conditions which closely approximate those generally used in commercial practice. “Pardes”, the Hebrew word for citrus orchard, is derived from the Persian “pairidaēza” which means ‘surrounded by a wall’. From the same word the word “paradise” was deducted. The described trees were grafted on ‘Troyer’ citrange—Citrus sinensis (L.) Osb.×Poncirus trifoliata L. (unpatented) and planted at a distance of 1.5×5 m in sandy red loam soil at an elevation of about 30 meters above sea level with irrigation of 100 m3 per hectare during summer, and addition of 1 liter of fertilizer (N:P:K 7:3:7+micro-elements (trace elements) per 1 m3 of water. Average annual rainfall is about 550 mm, with an average 350 mm of rainfall in winter (December to February). Mean diurnal minimum temperature in January is 7.2° C., and mean diurnal maximum temperature in July is 30.8° C.
Unless otherwise stated, the detailed morphological description includes observations, measurements and values taken from 20111 to 2012 and based on four-year-old ‘HADASS’ trees grown in the orchard at the Volcani Center. Quantified measurements are expressed as an average or a range of measurements taken from a number of plants of ‘HADASS’. The measurements of any individual plant, or any group of plants, of the new variety may vary from the stated average or range.
Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), (1986), except where general colors of ordinary significance are used. Color values were taken under daylight conditions in full sunlight in the Volcani Center, Bet Dagan, Israel.
All of the plants of ‘HADASS’, insofar as they have been observed, have been consistent in all the characteristics described below.
