Abstract
The present variety of plum tree is characterized by a large size, vigorous, hardy, and very productive tree. By being self-unfruitful, blooming in the early season, and having a very prolific bloom, the present variety cross pollinates very well with ‘Yummy®beaut’ (U.S. Plant Pat. No. 13,478). The fruit matures under the ecological conditions described during mid June, with first picking on Jun. 12, 2003. The fruit is uniformly medium to small in size, mostly purple in skin color, clingstone in type, yellow in flesh color, very firm and crisp in texture, and very good in flavor.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
1. A new and distinct variety of plum tree, substantially as illustrated and described, that is most similar to its seed parent, ‘Purple Majesty’ (U.S. Plant Pat. No. 7,503), by being self-unfruitful and by producing plums that are mostly purple in skin color, firm in texture, and sweet in flavor, but is distinguished therefrom by blooming about one week earlier, by being a very good pollinator for ‘Yummy®beaut’ (U.S. Plant Pat. No. 13,478), and by producing plums that are somewhat smaller in size but mature about twelve days earlier.
