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 late season. The present variety produces a moderate bloom with an average amount of pollen to entice good bee activity to facilitate pollination. The fruit matures under the ecological conditions described during the last half of July, with first picking on Jul. 21, 2008. The fruit is uniformly large in size, full red in skin color, clingstone in type, globose in shape, full red in flesh color, firm in texture, and very good 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 its seed parent, ‘Fortune’ (unpatented) plum, by being self-unfruitful and by producing fruit that is similar in size, clingstone in type, and red in skin color, but is distinguished therefrom by producing fruit that is nearly full red in flesh color, that is globose in shape, that is much sweeter in flavor, and that matures about seven days later.
