Dans son centre de Pully, Agroscope crée et sélectionne de nouvelles variétés de vigne depuis 50 ans. Neuf nouveaux cépages ont été mis sur le marché depuis 1990. Solidement implantés dans le paysage vitivinicole suisse, ceux-ci couvraient 863 ha en 2014. Il s’agit principalement de cépages rouges sélectionnés pour leur résistance aux maladies, notamment à la pourriture du raisin. Leur potentiel agronomique et qualitatif suscite un tel intérêt qu’ils constituent près de 10% de l’encépagement rouge en Suisse et font leurs premiers pas hors de nos frontières.
