Abstract
The present invention relates to an interspecific tree and more particularly to a medium 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 late season. The present variety produces a very heavy bloom, but is pollen deficient and should have pollinators grafted in the center of the tree to entice good bee activity for sufficient pollination. The fruit matures under the ecological conditions described during the latter part of August, with first picking on Aug. 29, 2011. The fruit is uniformly large in size, dark purplish red in skin color, clingstone in type, globose in shape, full red in flesh color, firm 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 ‘Blackred VIII’ (U.S. Plant Pat. No. 20,863) interspecific tree by being self-unfruitful and by producing fruit that is clingstone in type, that is mostly dark red to black in skin color, that is large in size, that is sweet in flavor, and that matures in the latter part of August, but is distinguished therefrom by blooming much later, by being pollen deficient, and by producing fruit that is globose instead of oblate in shape, that is full red instead of pink in flesh color, and that matures about five days later.
