Abstract
The present invention relates to a new and distinct variety of peach tree, Prunus persica, broadly characterized by a medium size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described in late May, with first picking on May 29, 2006. The fruit is uniformly large in size, acidic and sweet in flavor, globose to oblate in shape, clingstone in type, firm and non-melting in texture, yellow in flesh color, and mostly red in skin color.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
1. A new and distinct variety of peach tree, substantially as illustrated and described, that is most similar to ‘Crown Princess’ (U.S. Plant Pat. No. 7,070) peach by producing peaches that are very firm and non-melting in texture, yellow in flesh color, and mostly red in skin color, but is distinguished therefrom by having reniform instead of globose glands, by being more productive, by requiring less chilling hours, and by producing fruit that tastes better and that matures about twelve days earlier.
