Abstract
The present invention relates to an interspecific tree and more particularly to a new and distinct variety broadly characterized by 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 mid to late season. The present variety produces a moderately 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 mid August, with first picking on Aug. 19, 2011. The fruit is uniformly medium to large in size, deep red in skin color, clingstone in type, globose in shape, nearly full red in flesh color, firm and crisp in texture, and excellent 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 similar to its sister, ‘Blackred VIII’ (U.S. Plant Pat. No. 20,863) interspecific, by being self-unfruitful and by producing fruit that is similar in size, clingstone in type, and firm in texture, but is distinguished therefrom by being pollen deficient and producing fruit that is darker red in flesh color, that is deep red instead of black in skin color, that is globose instead of oblate in shape, and that matures about eight days earlier.
