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 variety blooms during mid season and requires about 550 chilling hours. The fruit matures under the ecological conditions described in mid to late June, with first picking on Jun. 22, 2020. The fruit is uniform, very large in size, oblate in shape, clingstone in type, firm in texture, almost entirely red in skin color, white in flesh color, and sub-acidic in flavor.

We claim: 1. A new and distinct variety of peach tree, substantially as illustrated and described, that is most similar to its seed parent, ‘Pearl Princess V’ peach tree (U.S. Plant Pat. No. 19,919), by having a medium size tree, by blooming in the mid season, by having large showy blossoms, by being self-fertile, and by producing white flesh peaches that are mostly red in skin color, firm in texture, and sub-acid in flavor, but is distinguished therefrom by producing peaches that are larger in size, that are mostly oblate instead of globose in shape, that are clingstone instead of freestone in type, and that mature about three days earlier.
