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 grapevine generally resembling the Thompson Seedless Grapevine (unpatented), but distinguished by bearing, without girdling or application of a growth regulator, grapes of a size borne by the Thompson Seedless variety only when so treated and distinguished by bearing bunches of grapes which are substantially free from shatter in cold storage and when subsequently displayed for sale.
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 grapevine, I claim: 1. A new and distinct variety of grapevine, substantially as illustrated and described, characterized by its general resemblance to the Thompson Seedless grapevine (unpatented) in bearing elongated, seedless, light green grapes, but being distinguished therefrom and characterized as to novelty by bearing grapes which, without girdling or the application of a growth regulator, are of a size only attained in the Thompson Seedless variety by girdling and/or such application and which are borne in bunches which are substantially free from shattering even when held for a protracted period.
