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 blooms somewhat early and requires about 400 chilling hours. The fruit matures under the ecological conditions described in early June, with first picking on Jun. 3, 2007. The fruit is uniformly large in size, acidic and sweet in flavor, globose in shape, clingstone in type, firm and melting in texture, mostly red in flesh color, and mostly red in skin color.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
1. A new and distinct variety of nectarine tree, substantially as illustrated and described, that is similar to ‘Rose Bright’ (U.S. Plant Pat. No. 15,845) nectarine by producing nectarines that are firm in texture, that are acidic and sweet in flavor, that are nearly full red in skin color, and that ripen in early June, but is distinguished therefrom by requiring less chilling hours and by producing fruit that has a much deeper suture at the apex, that is somewhat larger, and that is mostly red instead of yellow in flesh color.
