Knowledge of genetic diversity within a population is important for the conservation of the species. Our aim was to assess the genetic diversity in Draba dorneri Heuff. population (Brassicaceae family)—an endemic plant species of conservative interest using Random Amplified Polymorphic DNA (RAPD) technique. The plant species is strictly protected at national level as well as at international level through “Convention on the Conservation of European Wildlife and Natural Habitats”, Bern, 1979 European Council. In this study, a total of 52 primers were scored initially. A total of 77 repro- ducible bands with an average of 6.41 bands per primer were obtained from the 12 primers selected. A cluster analysis (UPGAMA) was used to generate a dendrogram based on Dice coefficient. We found 67% similarity between the samples from the two analyzed slopes. Comparing with other rare plants species, our data revealed a higher level of genetic diversity in D. dorneri population in Retezat Mountains.展开更多
