Abstract
The present invention relates to a plum tree, Prunus salicina, and more particularly to a new and distinct variety broadly characterized by a-medium 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, such as ‘Santa Rosa’ plum tree (unpatented). The present variety produces a heavy amount of flowers that produce an abundance of pollen to entice good bee activity to facilitate pollination. The fruit matures under the ecological conditions described during mid June, with first picking on Jun. 10, 2020. The fruit is uniformly medium in size, dark red in skin color, full deep red in flesh color, clingstone in type, globose in shape, firm in texture, juicy, very sweet, and very good in flavor.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
We claim: 1. A new and distinct variety of plum tree, Prunus salicina , substantially as illustrated and described, that is most similar to ‘Blackred VI’ interspecific tree (U.S. Plant Pat. No. 23,718), by being self-unfruitful and by producing fruit that is medium in size, firm in texture, sweet, very dark red in skin color, full deep red in flesh color, and clingstone in type, but is distinguished therefrom by blooming in the mid instead of early season and by producing fruit that is globose instead of oblate in shape, and that matures about 10 days earlier.
