Plum tree named ‘BLACKRED X’

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 to 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 to late season, such as ‘Blackred IV’ interspecific tree (U.S. Plant Pat. No. 20,832). The present variety produces a heavy amount of flowers that produce a moderate amount of pollen to entice good bee activity to facilitate pollination. The fruit matures under the ecological conditions described during late June, with first picking on Jun. 29, 2020. The fruit is uniformly medium in size, very dark purplish red in skin color, very dark red in flesh color, semi-freestone in type, globose in shape, firm in texture, juicy, very sweet, and very good in flavor.

We claim: 
     
       1. A new and distinct variety of plum tree,  Prunus salicina , substantially as illustrated and described, that is most similar to its seed parent ‘Blackred V’ interspecific tree (U.S. Plant Pat. No. 19,576), by being self-unfruitful and by producing fruit that matures in late June and that is fairly globose in shape, firm in texture, juicy, very sweet, and very good in flavor, but is distinguished therefrom by producing fruit that is somewhat darker red in flesh color, dark purplish red instead of genetically black in skin color, larger in size, semi-freestone instead of clingstone in type, and more tolerant to high temperatures during the harvest season.
