Abstract
The present invention relates to a peach tree, Prunus persica , and more particularly to a new and distinct variety characterized by a large 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 28, 2005. The fruit is large in size, sweet and sub-acidic in flavor, globose with some tipping on the apex in shape, clingstone in type, white in flesh color, mostly red in skin color, and firm in texture. The variety was developed as a first generation cross using an unnamed white flesh nectarine (unpatented) as the selected seed parent and an unnamed yellow flesh peach (unpatented) as the selected pollen parent.

No. 11,205) peach, by producing fruit that is clingstone in type, white in flesh color, mostly red is skin color, firm in texture, and sub-acid in flavor, but is distinguished therefrom by requiring much less chilling hours, by blooming earlier, and by producing fruit that matures about eight days earlier.
