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.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new and distinct variety of nectarine tree, substantially as illustrated and described, that 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.
