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 other plums that bloom during the mid to late season, such as ‘Blackamber’ (unpatented) or ‘Angeleno’ (U.S. Plant Pat. No. 2,747). The fruit matures under the ecological conditions described in early September, with first picking on Sep. 7, 2002. The fruit is uniformly large in size, globose to slightly oblate in shape, blackish red in skin color, mostly red in flesh color, clingstone in type, very firm and crisp in texture, and very good in flavor. The variety was developed as a first generation cross using ‘Freedom’ (unpatented) as the selected seed parent and an undetermined plum as the pollen parent.
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 ‘Angeleno’ (U.S. Plant Pat. No. 2,747) plum by being self-unfruitful and by producing plums that are nearly black in skin color, globose to oblate in shape, firm in texture, and mature in the late season, but is distinguished therefrom and an improvement thereon by producing plums that are larger in size, sweeter in flavor, juicier, and mostly red instead of pale yellowish green in flesh color.
