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 variety blooms during the late blooming season and requires about 700 chilling hours. The fruit matures under the ecological conditions described in mid to late August with the first picking on Aug. 21, 2018. The fruit is uniform, large in size, globose in shape, clingstone in type, firm in texture, mostly yellow in flesh color, mostly red and orange in skin color, and traditional peach in flavor.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
We claim: 1. A new and distinct variety of peach tree, substantially as illustrated and described, that is most similar to ‘Summer Princess’ peach (U.S. Plant Pat. No. 25,793) by having large blossoms, by being self-fertile, and by producing peaches that are mostly red to orange in skin color, mostly yellow in flesh color, large in size, clingstone in type, globose in shape, and firm in texture, but is distinguished therefrom by requiring more chilling hours, by having reniform instead of globose leaf glands, and by producing fruit that is somewhat sweeter and that matures about twenty days earlier.
