Abstract
The present invention relates to a new and distinct variety of peach tree, Prunus persica , broadly characterized by a large size, vigorous, hardy, self-fertile, productive and regular bearing tree. The variety blooms during the early to mid season and requires about 450 chilling hours. The fruit matures under the ecological conditions described in late August, with first picking on Aug. 24, 2011. The fruit is uniform, very large in size, sub-acidic in flavor, globose in shape, freestone in type, firm and melting in texture, white in flesh color, mostly red in skin color, and good 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 peach tree, substantially as illustrated and described, that is most similar to its seed parent ‘Snow Princess’ peach (U.S. Plant Pat. No. 12,570) by producing fruit that is white in flesh color, mostly red in skin color, globose in shape, freestone in type, and sub-acidic in taste, but is distinguished therefrom by having globose instead of reniform leaf glands and by producing fruit that is somewhat larger in size and that matures about twenty days later.
