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 fruit matures under the ecological conditions described in late August, with first picking on Aug. 24, 2006. The fruit is uniformly large in size, sub-acidic and sweet in flavor, globose in shape, clingstone in type, firm in texture, white in flesh color, and almost full red with only slight freckling 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 most similar to its selected pollen parent, ‘Regal Pearl’ (U.S. Plant Pat. No. 11,695) nectarine, by producing nectarines that are nearly globose in shape, firm in texture, sub-acidic in flavor, and white in flesh color, but is distinguished therefrom by having a lower chilling requirement, by having globose instead of reniform leaf glands, by having a sweet instead of bitter kernel, and by producing nectarines that have much less skin freckling, that are somewhat larger in size, and that mature about one week later.
