Common name in Switzerland (French: vieux plants) for the mostly very old ones autochthonous Grape varieties, especially in the canton Wallis (French Valais) can be cultivated. Some come from the Italian region above the border aosta Valley or are also partially cultivated there. The two areas form a geographical island across borders with a large common grape variety pool. Many of these grape varieties form individual groups with related relationships that have developed over centuries. The sometimes very close genetic connections are due to the geographical isolation.
By the Swiss biologist Dr. José Vouillamoz (University in Neuchâtel) were a hundred varieties from the Swiss Valais, as well as from the Italian regions aosta Valley. Lombardy. Piedmont. Trentino and Friuli examined. The DNA-characteristics have been added to the database of over a thousand varieties University of California compared in Davis and clarified many lineages and relationships.
