Résumé
Within the scope of a European project (GenRes 081), along with the development of a database (The European Vitis Database: http://www.dainet.de/eccdb/vitis), we developed a method of scoring the microsatellite data, which enables easy comparison of microsatellite data between laboratories. Six microsatellite loci have been selected for this project: VVS2, VVMD5, VVMD7, VVMD27, VrZag62 and VrZag79. These locus are effective for the discrimination of grapevine cultivars. This strategy is based on the coding of the alleles according to reference cultivars, well known over the world. For each of the 6 loci, a set of 10 to 16 reference cultivars were chosen, representing 13 to 23 alleles.
