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 large size, vigorous, hardy, productive and regular bearing tree. The fruit matures under the ecological conditions described approximately the first week in June, with first picking on June 3, 1988. The fruit is uniformly large in size, good in flavor, attractively oblate in shape, clingstone in type, very firm in texture making excellent quality for keeping and shipping, and almost full red in skin color at harvest time. The variety was developed as a hybridized seedling from the selected seed parent, Red Diamond (U.S. Pat. No. P.P. 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 ripening variety of clingstone peach tree, substantially as illustrated and described, which most nearly resembles the Merrill Gemfree (U.S. Pat. No. P.P. 1,409) peach variety by producing fruit that matures at nearly the same time, but is distinguished from and an improvement on that variety by having almost full red skin color at ripening time, by being extremely firm and non-melting in texture, by being clingstone in type, and by having a more desirable oblate shape.
