مقایسه فاصله ژنتیکی برخی از خانواده های ناتنی یونجه بر اساس نشانگرهای ایزوزیمی

Genetic diversity of 12 alfalfa half-sib families was studied by use of peroxidase and esterase enzymes electrophoresis. The resulting data based on presence and absence of enzymatic band (0 and 1) for 11 polymorphic isozymic bands were analyzed. Isozymic analysis showed that there were high level of intra-family and low level of inter-family diversity. Average heterozygosity, as an index of within-population genetic diversity, was 0.289. Nei’s genetic distances among families were low (0.002 to 0.059). Dendrogram was constructed via the Jaccard similarity coefficient and UPGMA method, that lead to the classification of the alfalfa populations in two groups, with 11 families in one group and only Chaleshte half-sib in the other group were located that were conform the pervious conclusion. In conclusion, small differences were observed among half-sib families for studied parameters.
