No cultivar name of record
This patent does not name the plant. Through the 1980s and early 1990s that was still common: naming every new cultivar only became standard practice as plants began to be marketed under brand names. The grant identifies this one by its number and by a written description instead.
Nothing here is missing from our records: the patent itself states no name. Where one exists we show it, and we do not invent one.
Abstract
The present invention relates to a plum tree and more particularly to a new and distinct variety broadly characterized by a medium size, medium vigorous, hardy, productive, and regular bearing tree, which requires a pollinator. The fruit matures under the ecological conditions described in the latter part of June, with first picking on June 19, 1989, and is uniformly large in size, clingstone in type, very dark purplish red in skin color, smooth in surface appearance, attractive in shape, sweet in flavor, and exceptionally firm in texture, resulting in excellent quality for keeping and shipping. The variety was developed as a hybridized seedling from the selected seed parent, Red Beaut (U.S. Plant Pat. No. 2,539), and an unnamed seedling as the selected pollen parent.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
We claim: 1. A new and distinct variety of plum tree, substantially as illustrated and described, which matures at nearly the same time as Santa Rosa, unpatented, but is distinguished therefrom and an improvement thereon by producing fruit that is larger in size, much firmer in texture, darker in skin color at shipping ripeness, and axially compressed in shape.
