The white grape variety is an interspecific new variety between Seibel 6468 (Seibel 4614 x Seibel 3011) x Seibel 6905 (Subereux). Synonyms are 12-375 Seyve-Villard, 12-375 SV, Eger 2, Seyve-Villard 12-375 and SV 12-375. Genes from Vitis berlandieri, Vitis rupestris and Vitis vinifera are included. The hybrid was crossed in France at the Seyve-Villard vineyard in Saint-Vallier (Département Drôme) and, along with the Seyval Blanc variety, was one of the most successful breeds there. Due to its good characteristics, such as resistance to fungal diseases, it was a popular crossing partner (often under the name Eger 2) in many new crosses.
