Plum tree named ‘Plumred IV’

Abstract

The present invention relates to a plum tree, Prunus salicina, and more particularly to a new and distinct variety broadly characterized by a large size, vigorous, hardy, and moderately productive tree. Being self-unfruitful, the present variety requires cross pollination from an apricot, interspecific, or plum that blooms during the early season, such as ‘Blackred I’ interspecific tree (U.S. Plant Pat. No. 19,537). 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 early June, with first picking on Jun. 8, 2020. The fruit is medium in size, a solid dark purplish red skin color, full red to pink in flesh color, clingstone in type, oblate in shape, firm in texture, juicy, 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 ‘Blackred I’ interspecific tree (U.S. Plant Pat. No. 19,537), by blooming in the early season, by being self-unfruitful, and by producing fruit that is oblate in shape, firm in texture, fairly red in flesh color, and clingstone in type, but is distinguished therefrom by producing fruit that is dark red instead of black in skin color, that is a little sweeter and better in flavor, that is somewhat larger in size, and that matures about eight days later.
