Abstract

The present invention relates to a plum tree, Prunus salicina, and more particularly to a new and distinct variety broadly characterized by a medium 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 Fortune (unpatented) The fruit matures under the ecological conditions described during the last week in June, with first picking on Jun. 29, 2002. The fruit is uniformly medium in size, a two-tone purple over yellow in skin color, clingstone in type, purely yellow with no red bleeding in flesh color, very firm and crisp in texture, very good in flavor, and holds well in cold storage for more than thirty days. The variety was developed as an open pollinated seedling of ‘Ambra’ (unpatented).

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 Blackamber (unpatented) plum by being self-unfruitful, by blooming in the mid season and by producing plums that are somewhat oblate in shape, medium in size, and mature in the mid season, but is distinguished therefrom and an improvement thereon by blooming heavier, by producing more pollen, and by producing plums that are a purple over yellow two-tone in skin color rather than black, that are much sweeter in flavor, and that mature about one week earlier.
