Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0010] The accompanying photographs illustrate the overall appearance of the new Persea americana P. Mill. variety TAMI 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 TAMI. Plants shown in the photographs are approximately two years old.

DETAILED BOTANICAL DESCRIPTION

[0015] The new Persea americana P. Mill. TAMI 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.

[0016] The aforementioned photographs, together with the following observations, measurements and values describe trees of TAMI as grown in the orchard 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 64 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.

[0017] Unless otherwise stated, the detailed morphological description includes observations, measurements and values taken from 2014 to 2015 and based on two-year-old TAMI 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 TAMI. The measurements of any individual plant, or any group of plants, of the new variety may vary from the stated average or range.

[0018] 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.

[0019] All of the plants of TAMI, insofar as they have been observed, have been consistent in all the characteristics described below. [0020] Classification: [0021] Botanical.Persea americana P. Mill. [0022] Propagation: Frolich method. [0023] Growing conditions: [0024] Light intensities.Full sunlight.
