Genetic diversity among Turkish local grape accessions (Vitis vinifera L.) using RAPD markers.
To estimate genetic relationships among 46 local grape cultivars, RAPD analysis was performed with 25 decamer primers selected from a total of 60 primers. Genetic relationships among these cultivars were determined by calculating similarity indexes, from which a dendogram was derived. There was high genetic variation among the cultivars, with values of genetic diversity ranging from 0.553 to 0.952 using the Jaccard coefficient. UPGMA analysis of a distance matrix produced a dendogram with six clusters. The relatively high genetic similarity ratios observed for the cultivars was also reflected in the dendogram. In general, no relationship was encountered between the genetic similarity ratios of the cultivars and the results of previous ampelographic analyses.
