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 approximately the first week in July, with first picking on Jul. 6, 2001. The fruit is uniformly large in size, subacid in flavor, globose in shape, freestone in type, firm in texture, yellow 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 an unnamed 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 ‘Grand Sweet’ (U.S. Plant Pat. No. 11,954) nectarine by producing nectarines that are subacid and sweet in flavor and full red in skin color, but is distinguished therefrom and an improvement thereon by producing fruit that is freestone instead of clingstone, that matures about two weeks
