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 early to mid season. The fruit matures under the ecological conditions described during mid June, with first picking on Jun. 9, 2007. The fruit is uniformly medium in size, dark purplish red in skin color, clingstone in type, oblate in shape, red in flesh color, firm in texture, and mildly acidic and sweet 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 Yummybeaut (U.S. Plant Pat. No. 13,478) plum by being self-unfruitful and by producing fruit that is medium in size, that is firm in texture, that is clingstone in type, and that matures in mid June, but is distinguished therefrom by producing fruit that is darker in skin color, that is more oblate in shape, that has a less distinguishable suture, and that is red in flesh color instead of yellow.
