Abstract
The present invention relates to a new and distinct variety of peach tree, Prunus persica, broadly characterized by a small size, somewhat weak, hardy, self-fertile, productive and regular bearing tree. The variety blooms during the early to mid season and requires about 475 chilling hours. The fruit matures under the ecological conditions described in mid September, with first picking on Sep. 13, 2011. The fruit is uniformly large in size, globose in shape, freestone in type, firm and melting in texture, white in flesh color, mostly red to pink in skin color, and lightly acidic 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 pollen parent ‘Snow Duchess’ peach (U.S. Plant Pat. No. 17,281) by producing peaches that are white in flesh color, mostly red to pink in skin color, globose in shape, and freestone in type, but is distinguished therefrom by producing fruit that is larger in size and that matures about thirty days later.
