\nIl y a vingt ans, rappelle Guillaume Favre<\/b>, dans le Bulletin du Service d\u2019agriculture du Valais<\/i>, un projet a \u00e9t\u00e9 initi\u00e9 pour sauvegarder la biodiversit\u00e9 des c\u00e9pages du Vieux-Pays. Au d\u00e9part, 1’300 types des14 c\u00e9pages traditionnels du canton ont \u00e9t\u00e9 mis en conservatoire. Parmi eux, 109 types de petite arvine. Sur son domaine exp\u00e9rimental de Leytron, Agroscope-Changins, d\u00e8s 1995, a \u00e9tudi\u00e9 le comportement de 20 types d\u2019arvine. Au vu des r\u00e9sultats de ces \u00e9tudes, \u00abla marge de s\u00e9lection de la petite arvine para\u00eet extr\u00eamement importante\u00bb<\/i>, note l\u2019auteur.
\nAu Grand Br\u00fbl\u00e9, sur le domaine exp\u00e9rimental cantonal, d\u00e8s 2006, une parcelle a \u00e9t\u00e9 constitu\u00e9e pour \u00e9tudier les types de petite arvine sauvegard\u00e9s et les 109 types sont en voie de caract\u00e9risation (2012). Ce travail devrait permettre d\u2019am\u00e9liorer la s\u00e9lection massale de la marque \u00abS\u00e9lection Valais\u00bb<\/i> et de profiler de nouveaux clones certifi\u00e9s. Les types les plus prometteurs feront l\u2019objet de micro-vinifications.
\nQuelque 750’000 francs seront investis durant 12 ans sur ce projet pour assurer la p\u00e9rennisation et la mise en valeur du plus prometteur des c\u00e9pages blancs typiquement valaisans.<\/div>\n
Agroscope s’est joint au projet du Grand-Br\u00fbl\u00e9 en 2021 <\/strong><\/a>pour poursuivre la recherche viticole.<\/em>
