Abstract
The present invention relates to a plum tree, Prunus salicina , and more particularly to a new and distinct variety broadly characterized by a small 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, such as ‘Blackred III’ (U.S. Plant Pat. No. 18,668) interspecific tree. 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. 14, 2021. The fruit is medium to large in size, dark purplish red in skin color, full dark red in flesh color, clingstone in type, oblate in shape, firm in texture, juicy, moderately 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 dark purplish red in skin color, that is oblate in shape, that is clingstone in type, that is firm in texture, and that is very good in flavor, but is distinguished therefrom by blooming in the mid season instead of early season and by producing fruit that is larger in size, that is much darker red in flesh color, and that matures about 7 days earlier.
