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
A nectarine tree broadly bearing yellow-fleshed fruit of large size and resembling the Sun Grand Variety (U.S. Plant Pat. No. 974), but which bears fruit which attains an overall red coloration without exposure to sun, which ripens evenly, and which ripens about one week earlier than that of the Sun Grand.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
Having thus described and illustrated my new variety of nectarine tree, what is new and desired to be secured by Letters Patent is: 1. A new and distinct variety of nectarine tree, substantially as illustrated and described, broadly characterized by bearing yellow-fleshed fruit of large size and by its general resemblance to the Sun Grand Nectarine Tree (U.S. Plant Pat. No. 974) of which it is believed to be a mutant but from which it is distinguished as to novelty by its fruit attaining an overall full red coloration even along its suture without overall exposure to sun, and by its fruit ripening substantially all at the same time and about one week earlier than the fruit of the Sun Grand.
