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 approximately the second week in August, with first picking on Aug. 9, 2002. The fruit is uniformly large in size, excellent in flavor, globose in shape, clingstone in type, very firm in texture, white 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 an unnamed white flesh 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 ‘Fire Pearl’ (U.S. Plant Pat. No. 9,358) nectarine by producing white flesh clingstone nectarines that are firm in texture, mostly red in skin color, and sweet subacid in flavor, but is distinguished therefrom and an improvement thereon by having reniform instead of globose leaf glands, by having small non-showy instead of large showy blossoms, and by producing nectarines that are much larger in size and mature about ten days later.
