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 peach tree and more particularly to a new and distinct variety broadly characterized by a medium size, vigorous, hardy, very productive and regular bearing tree. The fruit matures under the ecological conditions described approximately the last week in June, with first picking on June 27, 1988, making it an early to mid-season ripening peach. The fruit is uniformly large in size, globose in shape, freestone in type, very firm in texture making excellent quality for keeping and shipping, almost full red in skin color at harvest time, and a delicious balance of acid and sugar in flavor. The variety was developed as a hybridized seedling from the selected seed parent, Red Diamond (U.S. Plant Pat. No. 3,165) nectarine, and an unnamed peach 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 early to mid-season ripening variety of freestone peach tree, substantially as illustrated and described, which most nearly resembles the Redtop (not patented) peach variety by producing fruit that is freestone in type and ripens in late June, but is distinguished from and an improvement on that variety by having fruit that is more fully red in color at harvest time, more globose in shape, and much firmer in texture, all valuable assets for commercial long distant shipping peach varieties.
