Abstract
The present invention relates to a new and distinct variety of peach tree, Prunus persica , broadly characterized by a medium size, moderately vigorous, hardy, self-fertile, very productive and regular bearing tree. The variety blooms during the early to mid season and requires about 500 chilling hours. The fruit matures under the ecological conditions described in the later part of July, with first picking on Jul. 21, 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 pollen parent ‘Snow Princess’ peach (U.S. Plant Pat. No. 12,570) by producing peaches that are white in flesh color, mostly red in skin color, firm in texture, large in size, freestone in type, and sub-acidic in taste, but is distinguished therefrom by blooming about five days later and by producing fruit that matures about two weeks earlier.
