Abstract
The present invention relates to an interspecific tree and more particularly to a medium size, moderately vigorous, hardy, and very productive tree. Being self-unfruitful, the present variety requires cross pollination from an apricot, interspecific, or plum that blooms during the early season. The present variety's abundance of blossoms and moderate pollen production entices strong bee activity to facilitate pollination. The fruit matures under the ecological conditions described during the latter part of August, with first picking on Aug. 23, 2008. The fruit is uniformly large in size, blackish red in skin color, clingstone in type, oblate in shape, mostly red to orange in flesh color, firm in texture, and outstanding in flavor.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
1. A new and distinct variety of interspecific Prunus sp. tree, substantially as illustrated and described, that is similar to ‘Plumsweet V’ (U.S. Plant Pat. No. 16,369) interspecific tree by being self-unfruitful and by producing fruit that is clingstone in type, that is mostly dark purple to black in skin color, that has a significant degree of red in the flesh color, that is very sweet in flavor, and that matures in the latter part of August, but is distinguished therefrom by blooming earlier and by producing fruit that is much larger in size, more oblate in shape, less juicy, and much less prone to shoulder wrinkling after harvest.
