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 in mid August, with first picking on Aug. 12, 2002. The fruit is uniformly large in size, sweet and acidic in flavor, globose in shape, clingstone in type, firm in texture, yellow in flesh color, and mostly red in skin color. The variety was developed as a first generation cross using ‘August Red’ (U.S. Plant Pat. No. 6,363) nectarine as the selected seed parent and ‘Diamond Princess’ (U.S. Plant Pat. No. 7,066) peach 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 ‘August Bright’. The present variety was hybridized by me in 1989, 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 ‘August Red’ (U.S. Plant Pat. No. 6,363) nectarine as the selected seed parent and ‘Diamond Princess’ (U.S. Plant Pat. No. 7,066) peach 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’ (unpatented) rootstock upon which the present variety was compatible and true to type.
The present variety is similar to its selected pollen parent, ‘Diamond Princess’ (U.S. Plant Pat. No. 7,066) peach, by producing fruit that is yellow in flesh color and nearly full red in skin color, but is quite distinguished therefrom by producing fruit that is nectarine instead of peach, that is clingstone instead of freestone, and that matures about thirty-five days later.
The present variety is most similar to its selected seed parent, ‘August Red’ (U.S. Plant Pat. No. 6,363) nectarine, by producing nectarines that are nearly globose in shape, very firm in texture, clingstone in type, mostly red in skin color, and yellow with some red streaking in flesh color, but is distinguished therefrom by producing fruit that matures about two weeks earlier and that has a sweet kernel instead of bitter.
SUMMARY OF VARIETY
In summary, the present variety is characterized by a medium size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described in mid August, with first picking on Aug. 12, 2002. The fruit is uniformly large in size, sweet and acidic in flavor, globose in shape, clingstone in type, firm in texture, yellow in flesh color, and mostly red in skin color.
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
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 Valley), Calif., and was developed at the state of firm ripe on Aug. 15, 2002, on a six year old tree budded on ‘Nemagard’ (unpatented) rootstock. All major color code designations are by reference to the Inter-Society Color Council, National Bureau of Standards. Common color names are also used occasionally.
