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 rootstock is provided. It is characterized by its immunity to feeding by the nematode vector of grapevine fanleaf virus and to feeding by phylloxera. When grafted with scion cultivars, such as `Cabernet Sauvignon,` `Chenin blanc,` and `Carignane,` the variety may be planted in soil contaminated with viruliferous nematodes and/or phylloxera and will produce healthy fruit and excellent yields.
