Abstract
The present invention relates to a new and distinct variety of nectarine tree, Prunus persica , broadly characterized by a medium size, moderately vigorous, half-hardy, self-fertile, very productive and regular bearing tree. The variety blooms early and requires about 350 chilling hours. The fruit matures under the ecological conditions described in early June, with first picking on Jun. 4, 2010. The fruit is uniformly large in size for an early season variety, globose in shape, clingstone in type, firm and melting in texture, white in flesh color, mostly red in skin color, and a tasty balance of sweet sub-acid and traditional nectarine flavors.
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 ‘May Pearl’ (U.S. Plant Pat. No. 17,254) nectarine by producing nectarines that are white in flesh color, clingstone in type, firm in texture, and mostly sub-acidic in flavor, but is distinguished therefrom by requiring slightly less chilling hours, by having reniform instead of globose leaf glands, and by producing fruit that is larger in size, that is a fuller red in skin color, and that matures about ten days later.
