Important French vine-growing business in Saint-Vallier an der Drôme in the Rhone Valley, which was founded by the breeder Bertille Seyve (1864-1939) and his father-in-law and partner Victor Villard. The sons Bertille Seyve jr. (1895-1959) and Joannes Seyve (1900-1966). From the end of the 19th century there were over a hundred French new varieties by crossing between American vines respectively. hybrids With Europeans Vines developed. They were mostly hybrids of the so-called second generation, because many became hybrids of the French breeder Albert Seibel (1844-1936) used as an intersection partner. The grape varieties were mostly given the company name (Seyve, Seyval, Seyve-Villard or Villard) and a serial number, some of which later received a sounding name. Numerous hybrids have also emerged as the basis for new varieties under the name Joannes Seyve plus serial number. The most famous creation got the name Chambourcin (JS 26-205).
The most successful Seyve Villard varieties, some of which were crossbreeding partners for other varieties Dattier de St. Vallier (SV 20-365), Garonnet (SV 18-283), Pierrelle (SV 20-366), Roucaneuf (SV 12-309), Seyval Blanc (SV 5276), Seyve-Villard 12-286. Seyve-Villard 12-481. Seyve-Villard 18-402. Valerien (SV 23-410), Varousset (SV 23-657), Villard Blanc (SV 12-375) and Villard Noir (SV 18-315). The American wine pioneer Philip wagner (1904-1996) from Maryland was largely responsible from the 1940s for many of these varieties to be found on the entire east coast of the United States widespread in many states. At the end of the 1960s, the vineyards in France were still around 60,000 hectares, but they were almost completely cleared due to EU regulations (hybrid ban). In England, Japan and the eastern United States, however, some are still widespread today, because in cool areas the early ripening and mostly against frost and fungal diseases resistant vines are of great advantage.
