Almond tree (Morley)

Abstract

The present invention relates to an almond tree and more particularly to a new and distinct variety broadly characterized by a large size, vigorous, upright, hardy, very late blooming, very productive, and regular bearing tree whose nuts mature under the ecological conditions described approximately the second week in September. The nuts are very well sealed to protect kernels that are uniformly medium in size, dark in color, and ovate in shape.

Description

BACKGROUND OF THE VARIETY

In a continuing effort to improve the quality of shipping fruits and nuts, we, the inventors, typically hybridize a large number of nectarine, peach, plum, apricot, cherry, and almond seedlings each year. The present invention relates to a new and distinct variety of almond tree, which has been denominated varietally as "Morley". The present variety was selected in 1982 by us in a cultivated area of our experimental orchard at Bradford Farms near Le Grand, Calif. in Merced County (San Joaquin Valley). This hybrid seedling resulted from using Texas Almond (unpatented) as the selected seed parent and an unnamed late blooming almond seedling as the selected pollen parent. Subsequent to origination of the present variety of almond tree, we asexually reproduced it by budding and grafting, and such reproduction of plant and nut characteristics were true to the original plant in all respects.

The tree of the present variety is most similar to that of its seed parent, the Texas (unpatented), by being vigorous and upright, but is distinguished therefrom by blooming one week later and by being a more consistent and heavier producer. The nuts produced by the present variety are also similar to those of the Texas variety by having kernels that are medium in size and dark in color, but are distinguished therefrom by being much less susceptible to doubling, by maturing two weeks earlier and by having shells that are more easily removed from the kernels by mechanical shelling processes with very little scratching and breaking.

The present variety differs significantly from the well known Nonpareil Almond (unpatented) variety in several ways, but most distinctively by blooming and harvesting approximately two weeks later.

CULTURAL CHARACTERISTICS

Resistance to insects: Resistant to kernel insect damage due to its very well sealed inner shell.

Susceptibility to budfailure: No obvious occurrences of budfailure have been observed as of yet.

Resistance to other diseases: No unusual susceptibilities noted.

Susceptibility to frost: No unusual susceptibility noted, but the exposure duration is shorter than most varieties due to the late onset of blooming.

Although the new variety of almond tree possesses the described characteristics under the ecological conditions at Le Grand, Calif., in the central part of the San Joaquin Valley, it is to be expected that variations in these characteristics may occur when farmed in areas with different climatic conditions, different soil types, and/or varying cultural practices.

Claims

1. A new and distinct variety of almond tree, substantially as illustrated and described, which is most similar to its seed parent, the Texas (unpatented), by being vigorous and upright in growth and by producing dark medium sized kernels that are protected from insects by a well sealed shell, but is distinguished therefrom and an improvement thereon by appearing to be a heavier and more consistent producer, by blooming one week later while harvesting two weeks earlier, and by producing nuts that are much less prone to doubling and much easier to shell without causing mechanically induced damage to the kernel.
