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

An improved nectarine tree originating as a bud mutation of Stark "Red Gold". This new variety produces freestone fruit the skin of which is a full deep red when fully ripe and which is mottled with yellow in the ripening stages, full ripeness occurring some two to three days earlier than the fruit of the parent variety.

Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.

I claim: 1. A new and distinct variety of nectarine tree similar to its parent Stark "Red Gold" except for the darker redder color of the fruit skin and the slightly earlier maturation of the fruit, together with the tendency for the leaves to be slightly lighter in color than those of the parent and slightly more folded in form as shown and described.
