Major French vineyard in Saint-Vallier at the Drôme in the Rhone Valley founded by the breeder Bertille Seyve (1864-1939) and his father-in-law and partner Victor Villard. The sons Bertille Seyve Jr were later also in operation. (1895-1959) and Joannes Seyve (1900-1966). Here were from the late 19th century over a hundred French new varieties by crossing between American vines or. hybrids With Europeans Vines developed. They were mostly hybrids of the so-called second generation, because many of them became hybrids of the French breeder Albert Seibel (1844-1936) used as a Krezungspartner. The grape varieties were usually named with the company name (Seyve, Seyval, Seyve-Villard or Villard) and a serial number, some of which later got a sounding name. Under the name Joannes Seyve plus running number, numerous hybrids have also emerged as the basis for new breeding. The most famous creation got the name Chambourcin (JS 26-205).
The most successful Seyve Villard varieties, some of which were again crossing partners for other varieties, are Dattier de St. Vallier (SV 20-365), Garonnet (SV 18-283), 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 viticulture pioneer Philip wagner (1904-1996) from Maryland was largely responsible for the fact that many of these varieties on the entire east coast of the United States spread in many states. In the late 1960s, the vineyards in France amounted to about 60,000 hectares, but due to the EU provisions (hybrid ban) they were almost completely cleared. In England, Japan and the eastern United States, however, some are still prevalent today, because in cool areas the early ripening and mostly against frost and fungal diseases resistant vines are of great benefit.
