Abstract
The present invention relates to a peach tree, Prunus persica, and more particularly to a new and distinct variety characterized by a medium size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described in early June, with first picking on Jun. 1, 2005. The fruit is large in size, sweet and acidic in flavor, globose with some tipping on the apex in shape, clingstone in type, yellow in flesh color, full red in skin color, and firm but melting in texture. The variety was developed as a first generation cross using ‘Ruby Diamond’ nectarine as the selected seed parent and ‘Crimson Lady’ peach as the selected pollen parent.
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 similar to its selected pollen parent, ‘Crimson Lady’ (U.S. Plant Pat. No. 7,953) peach, by producing fruit that is clingstone in type, mostly red in skin color, and yellow in flesh color, but is distinguished therefrom by requiring less chilling hours and by producing fruit that is larger in size, melting instead of in non-melting in texture, and that matures about five days later.
