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 early July, with first picking on Jul. 7, 2002. The fruit is uniformly large in size, sub-acidic and sweet in flavor, slightly oblong in shape, freestone in type, firm in texture, yellow in flesh color, and mostly red in skin color. The variety was developed as a second 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 freestone nectarine seedling 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 very firm in texture, nearly full red in skin color, yellow in flesh color, and sub-acidic in flavor, but is distinguished therefrom by producing nectarines that are larger in size, freestone instead of clingstone in type, mature about 5 days earlier, and have a sweet instead of bitter kernel.
