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 very large, vigorous productive grapevine, having a slender trunk and very long split straps, reddish brown bark, medium to long cane and round, slightly enlarged nodes and shoots basically green with reddish longitudinal striations and tips growing straight up, bifurcated and trifurcated tendrils, medium size bud, slightly pointed, medium size leaves with U shaped petiolar sinus; date of bloom and fruit ripening 7-10 days earlier than Superior Seedless (U.S. Plant Pat. No. 3,106) and 14 days earlier than Thompson Seedless (unpatented), clusters of medium size, loose to compact, seedless white colored berries irregular in size, mostly large, firm, crisp, attractive, sweet taste, attributable to an early high solids-sugar and low acid content.
