Authenticating accessions from an in vitro collection established for long term conservation has become a priority for numerous research laboratories. At Agroscope, the genotypic profiles of the grapevine accessions have been established using 38 microsatellites. The analysis of the results and comparison with those of a Swiss database and of an European database allowed to confirm the identity of the grape cultivars in the collection. 41 accessions representing 20 cultivars have thus been authenticated. The genotypic process also allowed to verify the results of crosses issued from the grapevine breeding programme of Agroscope by parentage analysis. Profiles from 8 recent cultivars were compared with those of their progenitors among others and thus confirmed their identity.
