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 present variety's abundance of blossoms and pollen entices strong bee activity to facilitate pollination. The fruit matures under the ecological conditions described during mid September, with first picking on Sep. 18, 2011, and will hang on the tree for about fifteen more days. The fruit is uniformly large in size, red mottled over a yellow background in skin color, clingstone in type, globose in shape, yellowish orange to red in flesh color, firm and crisp in texture, and very good in flavor.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new and distinct variety of interspecific Prunus sp. tree, substantially as illustrated and described, that is most similar to its sister variety ‘Plumred X’ (U.S. Plant Pat. No. 19,591) interspecific tree by being self-unfruitful yet productive, by blooming in the mid season, and producing fruit that is globose in shape, firm, crisp, juicy, sweet and very good in flavor, but is distinguished therefrom by producing fruit that is a yellow to red two-tone instead of full red in flesh color, that appears to be less prone to cracking, and that matures about ten day later.
