Abstract
The present invention relates to an interspecific plum tree, Prunus salicina× ( Prunus salicina×Prunus armeniaca ), and more particularly to a new and distinct variety broadly characterized by a medium size, vigorous, hardy, and self-unfruitful but productive tree. The fruit matures under the ecological conditions described during mid August, with first picking on Aug. 7, 2003. The fruit is uniformly large in size, two-tone red and yellow in skin color, semi-freestone in type, purely yellow in flesh color, firm in texture, very good in cold storage, and mildly acidic and very sweet in flavor, which is predominately plum with a hint of apricot.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new and distinct variety of interspecific plum tree, substantially as illustrated and described, that is most similar to its seed grandparent, ‘Bradgreen’ (U.S. Plant Pat. No. 8,498), by producing fruit that is globose in shape, acidic and sweet in flavor, firm in texture, and matures in mid August, but is distinguished therefrom by blooming about ten days later and by producing fruit that is two-tone red and yellow instead of purely green in skin color, that is semi-freestone rather than clingstone in type, that is less susceptible to skin scuffing, and that has a unique plum with a hint of apricot flavor.
