Abstract

The present invention relates to a nectarine tree, Prunus persica, and more particularly to a new and distinct variety broadly characterized by a large size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described in early August, with first picking on Aug. 6, 2002. The fruit is uniformly large in size, mildly acidic and sweet 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 ‘Summer Bright’ (U.S. Plant Pat. No. 7,049) yellow flesh nectarine as the selected seed parent and ‘August Snow’ (U.S. Plant Pat. No. 8,947) 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 ‘Royal Bright’. The present variety was hybridized by me in 1993, 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 ‘Summer Bright’ (U.S. Plant Pat. No. 7,049) yellow flesh nectarine as the selected seed parent and ‘August Snow’ (U.S. Plant Pat. No. 8,947) 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’ (unpatented) rootstock upon which the present variety was compatible and true to type.
The present variety is similar to its selected pollen parent, ‘August Snow’ (U.S. Plant Pat. No. 8,947) nectarine by producing nectarines that are nearly globose in shape and mature during the first week in August, but is quite distinguished therefrom by producing nectarines that are clingstone instead of freestone, yellow flesh instead of white, and acidic flavor instead of sub-acidic.
The present variety is most similar to its selected seed parent, ‘Summer Bright’ (U.S. Plant Pat. No. 7,049) nectarine, by producing nectarines that are nearly globose in shape, very firm in texture, clingstone in type, yellow in flesh color, and nearly full red in skin color, but is distinguished therefrom by producing fruit that is considerably larger in size and that matures about seventeen days later.
SUMMARY OF VARIETY
In summary, the present variety is characterized by a large size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described in early August, with first picking on Aug. 6, 2002. The fruit is uniformly large in size, mildly acidic and sweet 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. 8, 2002, on the original tree during its ninth growing season.

OTHER NOTES
Although the new variety of nectarine 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.
