Abstract
The present invention relates to a new and distinct variety of nectarine tree, Prunus persica, broadly characterized by a medium size, moderately 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 late May, with first picking on May 24, 2009. The fruit is uniformly medium to large in size for an early season variety, mildly acidic and sweet in flavor, globose in shape, clingstone in type, firm and melting in texture, yellow 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, medium to large in size for the early season, acidic in flavor type, yellow in flesh color, and nearly full red in skin color, but is distinguished therefrom by requiring less chilling hours and by producing fruit that is sweeter in flavor and that matures about ten days earlier.
