The white grape variety (also GM 6495-4) is a new variety between Saperavi Severny x(Foster's White Seedling x splendid grape). It contains genes from Vitis amurensis and Vitis vinifera. The hybrid was crossed in 1964 by Vilém Kraus (1924-2103) in Lednice in the former Czechoslovakia. The breeding and selection of the seedlings was then carried out in Geisenheim (Rheingau) under Dr. Helmut Becker (1927-1990). With the same parents the new variety Sibera was developed, which is an early ripening vine resistant to both types of mildew and frost and due to its loose berry structure less susceptible to botrytis. It produces full-bodied white wines. No stocks were reported in 2010 (Kym Anderson).
