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, productive and regular bearing tree. The fruit matures under the ecological conditions described approximately the first week in July, with first picking on Jul. 2, 2002. The fruit is uniformly large in size, excellent in flavor, globose in shape, clingstone in type, very firm in texture, white in flesh color, and red in skin color. The variety was developed as a first generation cross using ‘Red Glen’ (U.S. Plant Pat. No. 7,193) yellow flesh nectarine as the selected seed parent and ‘June Pearl’ (U.S. Plant Pat. No. 9,360) white flesh nectarine as the selected pollen parent.

Description

Botanical classification: Prunus persica.
BACKGROUND OF THE VARIETY
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 ‘CANDY PEARL’. The present variety was hybridized by me in 1994, 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 ‘Red Glen’ (U.S. Plant Pat. No. 7,193) yellow flesh nectarine as the selected seed parent and ‘June Pearl’ (U.S. Plant Pat. No. 9,360) white 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, ‘Red Glen’ (U.S. Plant Pat. No. 7,193) nectarine, by producing nectarines that are globose in shape, very firm in texture, clingstone in type, and full red in skin color, but is very distinguished therefrom and an improvement thereon by producing fruit that is white instead of yellow in flesh color, that is subacid instead of acid in flavor, and that matures about one month earlier.
The present variety is similar to its selected pollen parent, ‘June Pearl’ (U.S. Plant Pat. No. 9,360) nectarine, by producing nectarines that are white in flesh color, full red in skin color, and subacid in flavor, but is quite distinguished therefrom and an improvement thereon by producing fruit that is much larger in size and that matures about eighteen days later.
The present variety is most similar to ‘Kay Pearl’ (U.S. Plant Pat. No. 10,871) nectarine by producing white flesh nectarines that are firm in texture, full red in skin color, and sweet subacid in flavor, but is distinguished therefrom and an improvement thereon by having reniform instead of globose leaf glands and by producing nectarines that are clingstone instead of freestone, that have less skin freckling, that are somewhat larger in size, and that mature about six days later.
DRAWING
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.
POMOLOGICAL CHARACTERISTICS
