Abstract
The present invention relates to an interspecific tree and more particularly to a new and distinct variety broadly characterized by a small size, weakly 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 heavy bloom with an abundant amount of pollen to entice good bee activity to facilitate pollination. The fruit matures under the ecological conditions described during mid October, with first picking on Oct. 10, 2013, and can hang on the tree for up to two weeks. The fruit is medium in size, black in skin color, clingstone in type, globose in shape, orange in flesh color, firm in texture, and excellent flavor in flavor.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
We claim: 1. A new and distinct variety of interspecific Prunus sp. tree, substantially as illustrated and described, that is most similar to ‘Blackred XII’ (U.S. Plant Pat. No. 20,892) interspecific tree, by being self-unfruitful, by being much less vigorous, and by producing fruit that is full black in skin color, nearly globose in shape, firm in texture, juicy and very sweet, but is distinguished therefrom by being less vigorous, by blooming about four days earlier and by producing fruit that is full orange in flesh color instead of red, that is smaller in size, and that matures about two weeks later.
