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 capable of producing late harvest red table grapes similar to the Emperor variety but which is superior to Emperor in its heavier and more regular cropping and in its greater uniformity of color, largeness of berry size and better palatability.
