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, heavy blooming, pollen abundant self-unfruitful and usually productive tree. The present variety requires cross pollinization from another plum that blooms during the mid season, such as ‘Santa Rosa’ (unpatented). The fruit matures under the ecological conditions described during the second week in September, with first picking on Sep. 10, 2002. The fruit is uniformly medium in size, nearly full red in skin color, semi-freestone in type, yellow with some red bleeding in flesh color, very firm in texture, very good in flavor, and holds well in cold storage for more than forty days. The variety was developed using an unnamed plum seedling as the selected pollen parent and ‘Bradgreen’ (U.S. Plant Pat. No. 8,498) as the selected pollen parent.
