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 and distinct variety of grapevine having the ability to produce early market seedless table grapes and very large raisins. The variety is further characterized by its unusually large berries with only occasional traces of seed development, a cluster that is naturally self-thinning at blossom time and its adaptability to short pruning methods.
