Abstract
The present invention relates to an interspecific tree and more particularly to a new and distinct variety broadly characterized by a medium to large size, moderately vigorous, hardy, and medium 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's abundance of blossoms and pollen entices strong bee activity to facilitate pollination. The fruit matures under the ecological conditions described during late September, with first picking on Sep. 27, 2008. The fruit is medium to large in size, mostly black in skin color, clingstone in type, nearly globose in shape, and mostly red to orange in flesh color.
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’ interspecific tree (U.S. Plant Pat. No. 16,369) by being self-unfruitful and by producing fruit that is clingstone in type, that is mostly globose in shape, that matures in the late season, and that is very good in flavor, but is distinguished therefrom by producing fruit that is mostly black in skin color instead of mostly purple, that has more red and orange in its flesh color, that is larger in size, and that matures about thirty days later.
