Abstract
The present invention relates to a new and distinct variety of peach tree, Prunus persica, broadly characterized by a large size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described in mid May, with the first picking on May 19, 2006. The fruit is uniformly medium in size, acidic and sweet in flavor, oblate in shape, clingstone in type, firm and non-melting in texture, yellow in flesh color, and red mottled over yellow 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 ‘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 red in primary skin color, but is distinguished therefrom by requiring much less chilling hours, by having a sweet instead of bitter kernel, by having reniform instead of globose leaf glands, and by producing fruit that is smaller in size, that is flatter in shape, that has a light yellow background skin color, and that matures about three weeks earlier.
