Abstract
The present invention relates to a peach tree, Prunus persica , and more particularly to a new and distinct variety broadly characterized by a medium size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described approximately the third week in June, with first picking on Jun. 18, 2001. The fruit is uniformly medium in size, very good in flavor, globose in shape, clingstone in type, firm in texture, white in flesh color, and full red in skin color. The variety was developed as a self pollinated seedling of ‘Ivory Princess’ (U.S. Plant Pat. No. 11,205) white flesh peach.
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 parent, ‘Ivory Princess’ (U.S. Plant Pat. No. 11,205) peach, by producing white flesh clingstone peaches that are globose in shape, firm in texture, and mostly red in skin color, but is distinguished therefrom and an improvement thereon by producing fruit that matures about 10 days later.
