Abstract
The present invention relates to a new and distinct variety of nectarine tree, Prunus persica , broadly characterized by a small size, moderately vigorous, hardy, self-fertile, productive and regular bearing tree. The variety has large blossoms and blooms in the mid season, requiring about 550 chilling hours. The leaves are large and have globose glands. The fruit matures under the ecological conditions described in mid August, with first picking on Aug. 10, 2013. The fruit is large in size, globose in shape, clingstone in type, firm and melting in texture, white in flesh color, mostly red in skin color, and very sweet in flavor, and the kernel has a bitter taste.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new and distinct variety of nectarine tree, substantially as illustrated and described, that is most similar to ‘Snow Pearl’ (U.S. Plant Pat. No. 14,695) nectarine by having globose leaf glands, by having a large blossom that blooms in the mid season, by requiring about 550 chilling hours, by being self-fertile, and by producing white flesh clingstone nectarines that are firm and mostly red in skin color, but is distinguished therefrom by producing fruit that is larger in size, that matures about seven days earlier, that is sweeter, and that has a bitter kernel instead of sweet.
