The French Rebenzüchtung Victor Ganzin Victor (1838-1900) developed in 1879 through Kreuzung of the variety Aramon Noir with an American Wildreben Vitis rupestris a series of hybrid Unterlage & Unterlagsrebe, which he named shortly AxR (Aramon x Rupestris) after the parents. The most successful of these was the AxR 1 (in Frankreich, Australien and Neuseeland it is called ARG 1).

If I were to rate websites, you would deserve the highest rating. It is rare to come across websites that provide such a large amount of data and are still so intuitive to use. Respect for the lovingly researched and informatively prepared encyclopedia. Keep it up!
