| Popis: | In this research, genetic variation among 22 grapevine cultivars of Shahrood region and 3 cultivars from Sisakht city were evaluated using 6 ISSR primers. The used primers produced totally 69 bands, which 65 bands showed polymorphism among evaluated cultivars. Primers UBC825 with 16 bands and UBC857 with 6 bands produced the highest and lowest numbers of polymorphic bands, respectively. Polymorphism percentage using these markers was 94.1%. Mean of expected heterozygosis (He) and mean of Shannon index were 0.37 and 0.54, respectively. The highest (0.61) and lowest (0.48) amount of Shannon index was belong to the primers UBC 825 and UBC849, respectively. Also primer UBC825 showed the highest amount of the expected heterozygosity (0.42), highest number of effective allele (1.75) and highest number of different alleles (2). Cluster analysis using Jaccard similarity coefficients and UPGMA algorithm put the 25 studied cultivars in three different groups. The results of this study showed that ISSR markers can be used as effective tools to evaluate the genetic variation and to accelerate grapevine breeding programs. |
