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 new variety of nectarine discovered as a sport of a Regal Grand growing in Fresno County, located in the San Joaquin Valley of California. The new variety is characterized by fruit which, when mature, is highly colored, keeps well and is particularly suited for shipping.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
Having thus described and illustrated our 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, which generally is of a larger size and more vigorous than the Regal Grand variety, of which it is a sport, and which is a heavy and regular bearer of large, uniform, clingstone, globose to slightly oblong fruit having firm yellow flesh and yellow skin substantially overspread with bright red at maturity, reached approximately seven to ten days later than the fruit of the Regal Grand nectarine variety, the fruit of the new variety being particularly characterized by a prominent suture extended from the stem cup of the fruit to beyond the pistil point and displaying a yellow suture stripe until final stages of ripening.
