Abstract
The present invention relates to a nectarine tree, Prunus persica, and more particularly to a new and distinct variety broadly characterized by a medium size, vigorous, hardy, self-fertile, and productive tree that produces fruit that is uniformly medium in size, very good in flavor, globose in shape, clingstone in type, firm in texture, white in flesh color, and partially red in skin color. The fruit matures under the ecological conditions described approximately the first week in September, with first picking on Sep. 5, 2001. The variety was developed as a first generation cross using Fire Pearl (U.S. Plant Pat. No. 9,358) white flesh nectarine as the selected seed parent and September Red (U.S. Plant Pat. No. 5,664) yellow flesh nectarine as the selected pollen parent.
Description
Prunus persica.
In a continuing effort to improve the quality of shipping fruits, I, the inventor, typically hybridize a large number of peach, nectarine, plum, apricot, and cherry seedlings each year. The present invention relates to a new and distinct variety of nectarine tree, which has been denominated varietally as ‘LATE PEARL’. The present variety was hybridized by me in 1996, grown as a seedling on its own root in my greenhouse, and transplanted to a cultivated area of my experimental orchard at Bradford Farms near Le Grand, Calif. in Merced County (San Joaquin Valley). The variety was developed as a first generation cross using ‘Fire Pearl’ (U.S. Plant Pat. No. 9,358) white flesh nectarine as the selected seed parent and ‘September Red’ (U.S. Plant Pat. No. 5,664) yellow flesh nectarine as the selected pollen parent. Subsequent to origination of the present variety of nectarine tree, I asexually reproduced it by budding and grafting in the experimental orchard described above, and such reproduction of plant and fruit characteristics were true to the original plant in all respects. The reproduction of the variety included the use of ‘Nemaguard’ rootstock (unpatented) upon which the present variety was compatible and true to type.
The present variety is similar to its selected seed parent, ‘Fire Pearl’ (U.S. Plant Pat. No. 9,358) nectarine, by producing nectarines that are globose in shape, firm in texture, white in flesh color, and subacid and sweet in flavor, but is distinguished therefrom and an improvement thereon by producing fruit that matures about thirty-five days later.
The present variety is similar to its selected pollen parent, ‘September Red’ (U.S. Plant Pat. No. 5,664) nectarine, by producing nectarines that are medium in size, that are partially red in skin color and that mature in early September, but is distinguished therefrom and an improvement thereon by having globose instead of reniform glands and by producing fruit that is white in flesh color instead of yellow.
The accompanying photograph exhibits four whole fruits positioned to display the characteristics of the skin color and form, one fruit divided transversely to the suture plane to reveal the flesh and stone, and typical leaves.
Referring now more specifically to the pomological characteristics of this new and distinct variety of nectarine tree, the following has been observed under the ecological conditions prevailing near Le Grand, Merced County (San Joaquin County), Calif., and was developed at the state of full ripe on Sep. 12, 2001, on the original tree during its fifth growing season.

Although the new vareity of nectarine tree possesses the described charcteristics 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.
