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, 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 season. The fruit matures under the ecological conditions described during late August, with first picking on Aug. 28, 2007. The fruit is uniformly large in size, mostly red with grayish yellow mottling in skin color, clingstone in type, nearly globose in shape, and red 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 ‘September YUMMY’ plum (U.S. Plant Pat. No. 14,220) by being self-unfruitful and by producing fruit that is mostly red in skin color, that is clingstone in type, and that is very good in flavor, but is distinguished therefrom by producing fruit that is larger in size, that has red and yellow mottling on the skin, that is dark red in flesh color, and that matures about two weeks earlier.
