The white grape variety (also Colmar 2700 G) is a complex interspecific new breeding between Villaris x VRH 3159-2-12 (an intergeneric cross between Vitis vinifera x Muscadinia). It contains genes from Vitis berlandieri, Vitis rupestris and Vitis vinifera, as well as Muscadinia. The hybrid was nucleated in collaboration between INRA (Montpellier, France) and the Julius Kühn Institute (Siebeldingen, Palatinate, Germany) as part of a project launched in 2000 for the development of PIWI varieties. The same parents were used to create the new Voltis variety, which is totally resistant to powdery mildew and highly resistant to downy mildew. In 2016, no stocks were reported (Kym Anderson).
The wein.plus encyclopaedia is a comprehensive, well-researched reference work. Available anytime and anywhere, it has become an indispensable part of teaching, used by students and myself alike. Highly recommended!
