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 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 the latter half of June, with first picking on Jun. 20, 2008. The fruit is uniformly large in size, very dark red in skin color, semi-freestone in type, oblate in shape, red in flesh color, firm in texture, and sweetly acidic 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 ‘Yummybeaut’ (U.S. Plant Pat. No. 13,478) plum by being self-unfruitful and by producing fruit that is dark red to purple in skin color, firm in texture, and matures in the second half of June, but is distinguished therefrom by having a more prolific bloom, by producing more pollen, and by producing fruit that is sweeter in flavor, much larger in size, semi-freestone instead of clingstone, oblate instead of globose in shape, and dark red in flesh color instead of yellow.
