Background: The population size of plants affects on genetic variation. Materials and Methods: We studied the impact variation in populations Capparis spinosa (caper, Capparaceae) using RAPDs East Azerbaijan (Iran). Withinpopulation diversity was estimated based Nei's Shannon's Popgen, similarity among from a UPGMA dendrogram matrix distances obtained through SHAN. Difference level between small-sized large-sized tested Mann-Whitney U test, correlation geographical examined by Pearson test (SPSS, 11.3). Total partitioned into within AMOVA Arlequin. Results: polymorphism levels bands ranged 48.8% to 81.4%, within-population varied 0.1667 0.2630. Genetic smallsized (0.1667 0.1809) significantly lower than variations (0.2158 -0.2630) (N= 7, P 0.674, test). Conclusions: Population has dramatic its diversity. results revealed that fragmentation caper study region most likely occurred recently. low indicates high risk extinction suggests urgent conservation action is needed recover these populations.
