Abstract
The present invention relates to an interspecific tree and more particularly to a new and distinct variety broadly characterized by a medium size, medium to weak vigor, hardy, and very productive tree. Being self-unfruitful, the present variety requires cross pollination from an apricot, interspecific, or plum tree that blooms during the late season. The present variety produces a moderate amount of blossoms with sufficient pollen to entice good bee activity to facilitate pollination. The fruit matures under the ecological conditions described during late July, with first picking on Jul. 24, 2014. The fruit is uniformly medium in size, mostly red in skin color with moderate freckling, clingstone in type, globose to oblate in shape, mostly orange in flesh color, firm in texture, typically 19 brix, and 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 ‘Plumred VI’ (U.S. Plant Pat. No. 21,051) interspecific tree, by being self-unfruitful, by blooming during the late season, and by producing fruit that is mostly globose in shape, clingstone in type, medium in size, good in flavor, and red in skin color, but is distinguished therefrom by producing fruit that is mostly orange instead of red in flesh color and that matures about fourteen days later.
