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 between the early and mid season and requires about 525 chilling hours. The fruit matures under the ecological conditions described in early July, with first picking on Jul. 2, 2011. The fruit is very large in size, globose in shape, clingstone in type, firm and melting in texture, white in flesh color, mostly red in skin color, and a balance of acid and sugar in flavor.
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 ‘Kay Pearl’ (U.S. Plant Pat. No. 10,871) nectarine by producing nectarines that are white in flesh color, mostly red in skin color, and that typically mature in late June to early July, but is distinguished therefrom by having reniform instead of globose leaf glands and by producing fruit that is clinstone instead of freestone in type, that is much larger in size, and that is lightly acidic instead of sub-acidic in flavor.
