Inter-simple sequence repeat (ISSR ) markers were used to assess genetic diversity and structure of two populations of Papaver bracteatum and one population of Papaver somniferum. Fifteen ISSR primers amplified 135 lociwhich 117 (86.6%) were polymorphic. The genetic diversity estimated by Shannon’s information index (I) was 0.283 and 0.1 for P. bracteatum and P. somniferum, respectively. Eighty-three (61%) fragments were found to be useful as species-specific markers and 52 fragments were conserved between two species. Analysis of molecular variance (AMOVA) showed that the genetic variation mostly allocated to among species (64%). UPGMA clustering algorithm differentiated and classified studied genotypes and populations in three distinct groups. The result of the present study indicated a wide range of variation in the phenetic relationship among P. bracteatum and P. somniferum. Also, species-specific bands generated could be used to develop the species-specific sequence characterized amplified region (SCAR) markers.
