Mother: Villaris
Father: known as VRH/Mtp 3159-2-12, an intergeneric cross between Vitis vinifera x Muscadinia rotundifolia. Bred by INRA at Montpellier.
            It contains genes from Vitis berlandieri, Vitis rupestris and Vitis vinifera, as well as Muscadinia.

A white Piwi/disease-resistant variety. The French term for this is ResDur.

One of the first four French varieties resistant to fungal diseases, that in 2021 have become affiliated to the Vitis vinifera L. botanical taxon by the European Community Plant Variety Office (CPVO).
Now eligible for producing PDO wines; and on the fast track to French AOC recognition, a move that was previously unthinkable.

The cross-breeding strategy, using the technique of Marker-Assisted Selection (MAS), based on knowledge of resistance genes, is specific to the INRA ResDur program.
This has enabled selection of varieties which combine two downy mildew resistance genes and two powdery mildew resistance genes, originating from the species Vitis rotundifolia and a group of species dominated by Vitis rupestris. These new varieties are technically neither crossings nor hybrids.

The polygenic resistance of these varieties allows huge reducion in operating costs relating to the use of plant health products; 85% reduction in the use of treatments with fungicides, herbicides and insecticides.

Winter Pruning: long cane pruning is essential as the basal buds give little fruit.

Advantages: Late bud-burst. Extremely resistant to powdery and downy mildews.

Disadvantages: Very late ripening for England.
