Souvignier gris - resistant variety


This is a white fungus resistant cross made by the Weinbauinstitut Freiburg.

It was said for a long time that it is a cross of Cabernet Sauvignon X Bronner.

Recent genetic studies have concluded that it is a cross between Seyval blanc x Zaehringer. So it is now also carried out in the "Vitis International Variety Catalog". The question remains, however, where does Souvignier gris' good Peronospora resistance come from?

Seyval blanc is an old French hybrid variety.

Zaehringer is an old cross of the viticultural institute in Freiburg (Traminer x Riesling).


FR 392-83

Requirements to the site:

Souvignier gris needs a site which is also suitable for Pinot blanc.


For the moment not so much because the variety is new. There are plantings in Germany, Netherlands, and since 2017 quite big plantings in Italy and France.


The resistance against Downy Mildew is very good and also the resistance to Powdery Mildew is high. In normal years and circumstances no treatments will be necessary.
