Abstract
The present invention relates to an interspecific tree and more particularly to a new and distinct variety broadly characterized by a large size, vigorous, hardy, and productive tree. Being self-unfruitful, the present variety requires cross pollination from an apricot, interspecific, or plum that blooms during the mid season. The fruit matures under the ecological conditions described during late June, with first picking on Jun. 30, 2006. The fruit is uniformly large in size, full red to purple in skin color, clingstone in type, somewhat obovate to cordate in shape, significantly red in flesh color, firm in texture, and excellent in flavor.
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 interspecific Prunus sp. tree, substantially as illustrated and described, that is similar to ‘YUMMYrosa’ (U.S. Plant Pat. No. 13,476) plum by being self-unfruitful and by producing fruit that is clingstone in type and that matures in late June, but is distinguished therefrom by producing fruit that is firmer in texture, that has a higher amount of red skin color, that is entirely red to pink in flesh color, and that is larger in size.
