Abstract
The present invention relates to an interspecific tree and more particularly to a new and distinct variety broadly characterized by a medium 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 season. The fruit matures under the ecological conditions described during early July, with first picking on Jul. 7, 2007. The fruit is uniformly medium in size, mostly red with greenish yellow freckling in skin color, clingstone in type, oblate in shape, red in flesh color, very firm and crisp 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 ‘YUMMY®rosa’ (U.S. Plant Pat. No. 13,476) plum by being self-unfruitful and by producing fruit that is medium in size, that is clingstone in type, and that is somewhat oblate in shape, but is distinguished therefrom by having a flower that produces less pollen and by producing fruit that is firmer in texture, that is entirely red in flesh color, that has abundant greenish yellow freckling, that is somewhat sweeter in flavor, and that matures about seventeen days later.
