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, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described approximately the last week in June, with first picking on Jun. 24, 2001. The fruit is uniformly medium in size, excellent in flavor, globose in shape, clingstone in type, firm in texture, yellow to red in flesh color, and dark red in skin color. The variety was developed as a an open pollinated seedling of an unnamed plum possessing red skin and red flesh.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new and distinct variety of plum tree, substantially as illustrated and described, that is most similar to ‘Purple Majesty’ (U.S. Plant Pat. No. 7,503), by producing dark red plums that are firm in texture and mature about the third week in June, but is distinguished therefrom and an improvement thereon by being self-fertile, by producing an abundance of pollen, by being more productive, and by producing fruit that is red in flesh color toward the skin, juicier, and sweeter in flavor.
