Botanical name of the genus and species of the plant claimed: Persea americana P. Mill.
Variety denomination: ‘BEN-YA'ACOV1’.
The present invention relates to a new and distinct variety of avocado tree, botanically known as Persea americana P. Mill. of the Lauraceae family, and hereinafter referred to by the variety denomination ‘BEN-YA'ACOV1’.
Clonal avocado rootstocks were developed in Israel on a small scale between the years 1962 to 1977 and on a large scale in the years following. During the entire period about 220 different rootstocks have been developed in an attempt to solve soil problems caused by stress factors such as salinity, lime, poor aeration and root-rot, and various combinations of these factors, while simultaneously improving productivity. Uniformity among trees and dwarfness were also taken into account as part of the search for better rootstocks. The development process included field evaluation on a very large scale, in which 350 experiments and 65000 trees took part.
The new Persea americana P. Mill. ‘BEN-YA'ACOV1’ was discovered and selected by the inventors, Avraham Ben Ya'akov, Miriam Silberstein, and Vered Irihimovitch, growing in a cultivated area in the late 1970's in Ma'agan Michael, Israel. The new Persea americana P. Mill. ‘BEN-YA'ACOV1’ was selected by the inventors based on lower tendency towards alternate bearing, Phytophthora cinnamomi and salinity resistance, induced productivity on the grafted varieties.
Asexual propagation of the new Persea americana P. Mill. variety by the Frolich method for vegetative propagation was first performed in March 1980 in the Volcani Center, Israel and has demonstrated that the combination of characteristics as herein disclosed for the new variety are 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 ‘BEN-YA'ACOV’ which in combination distinguish this avocado tree as a new, unique and distinct variety:
Of the many varieties known to the present inventors, the most similar in comparison to the new Persea americana P. Mill. ‘BEN-YA'ACOV1’ is Persea americana P. Mill. ‘DEGANIA 117’ (unpatented) which differ from the new variety ‘BEN-YA'ACOV1’ in the characteristics described in Table 1:
The accompanying photographs illustrate the overall appearance of the new Persea americana P. Mill. variety ‘BEN-YA'ACOV1’ 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 ‘BEN-YA'ACOV1’. Plants shown in the photographs are approximately two years old.
The new Persea americana P. Mill. ‘BEN-YA'ACOV1’ 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 avocado plant.
The aforementioned photographs, together with the following observations, measurements and values describe trees of ‘BEN-YA'ACOV1’ as grown in The Volcani Center, Israel, under conditions which closely approximate those generally used in commercial practice. The described plants were propagated by the Frolich method and planted at a distance of 6×4 m in sandy red loam soil at an elevation of about 30 meters above sea level with 700-1000 m3 per dunam per season of irrigation and N:P:K 30:30:5 of fertilizers. 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 2014 to 2015 and based on two-year-old ‘BEN-YA'ACOV1’ plants/trees grown in the orchard in The Volcani Center, Israel. Quantified measurements are expressed as an average or a range of measurements taken from a number of plants of ‘BEN-YA'ACOV1’. 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 edition), except where general colors of ordinary significance are used. Color values were taken under daylight conditions in full sunlight in the Volcani Center, Israel.
All of the plants of ‘BEN-YA'ACOV1’, insofar as they have been observed, have been consistent in all the characteristics described below.
