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 July, with first picking on Jul. 13, 2001. The fruit is uniformly large in size, very good in flavor, globose in shape, freestone in type, firm in texture, yellow in flesh color, and mostly red in skin color. The variety was developed as a first generation cross using ‘Diamond Princess’ (U.S. Plant Pat. No. 7,066) yellow flesh peach as the selected seed parent and an unnamed white flesh peach as the selected pollen parent.
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 selected seed parent, ‘Diamond Princess’ (U.S. Plant Pat. No. 7,066) peach, by producing freestone 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 is subacid instead of acid in flavor, that is larger in size, and that matures about two weeks later.
