Microsatellite analysis to define genetic diversity of grapevines (<em>Vitis vinifera</em> L.) grown in Central and Western Mediterranean countries
PCR-based microsatellite analysis has been applied to define the relationships among 238 grapevine cultivars selected as representative of local germplasm in the Central and Western Mediterranean regions. The estimation of genetic distances among the five grapevines groups, based on cluster analysis...
