Abstract
The present invention relates to a new and distinct variety of nectarine tree, Prunus persica , broadly characterized by a medium size, vigorous, hardy, self-fertile, productive and regular bearing tree. The variety has a large showy blossom and blooms during the mid season, with a chilling requirement of about 550 hours. The fruit matures under the ecological conditions described in mid to late Mid to late August, with first picking on Aug. 18, 2021. The fruit is uniform, large in size, sub-acidic and very sweet in flavor, mostly globose in shape, clingstone in type, firm in texture, yellow in flesh color, mostly red in skin color, and has a bitter tasting kernel.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
We claim: 1. A new and distinct variety of nectarine tree, substantially as illustrated and described, that is most similar to ‘August Bright’ (U.S. Plant Pat. No. 15,143) nectarine, by having a medium size tree, by being self-fertile, by having reniform leaf glands, and by producing nectarines that are mostly red in skin color, that are yellow in flesh color, that are clingstone in type, and that mature in mid August, but is distinguished therefrom by having a bitter instead of sweet kernel, by having a genetically large instead of small flower, and by producing fruit that is somewhat larger in size, sub-acidic instead of acidic in flavor, and much sweeter.
