The genus Sedlitzia (Amaranthaceae) includes four herbaceous and one shrubby species. Sedlitzia rosmarinus is resistant to salinity that plays an important role in soil conservation. In this research, RAPD molecular markers were used to evaluate the genetic diversity among ۸۵ plant samples from ۱۷ populations of S. rosmarinus. Five primers were used to perform RAPD reactions and a total of ۴۰۰ DNA bands were obtained. After forming ۰ and ۱ matrix with the help of GenAlex ۶.۴۱ and UPGMA methods using SHAN clustering model, NTSYS Ver. ۲.۰۲ software was used to interpret RAPD analysis data. Molecular analysis of variance (AMOVA) was performed to estimate genetic diversity out of ۸۵ individuals. Out of the total diversity, it was calculated that, the highest amount of genetic diversity i.e. ۶۹% was related to intra-population and ۳۱% to inter-population diversity, respectively.
