Evaluation of genetic diversity among Tunisian grapevines by RAPD markers

Thirty-three native Tunisian grapevine varieties (Vitis vinifera L.), previ ously analysed with biochemical tools, were surveyed with RAPD markers, Ele ven primers amplified 54 clear and unambiguous markers. Five groups of vari eties were clearly resolved by UPGMA cluster analysis. These results allowe d the discrimination of groups of varieties that could not be discriminated by biochemical analyses. In addition, the dendrogram obtained could be sho wn being independent from both the phenotypic characters and the origin of the accessions.
