title: Inter- and intra-specific genetic  diversity of Iranian yarrow species Achillea santolina  and Achillea tenuifolia based on ISSR and RAPD  markers.
abstract: Cultivation  and preservation of yarrow has recently attracted wide attention due to its  beneficial properties; however, genetic variation of Achillea species is  still relatively unknown. We used RAPD and ISSR markers to assess genetic  diversity in 16 accessions of yarrow belonging to two species native to Iran.  Seven ISSR and nine RAPD primers generated 187 amplified fragments, of which  159 were polymorphic. The similarity coefficient among Achillea tenuifolia accessions  ranged from 61 to 86%, and from 40 to 84% among A. santolina accessions.  A low similarity was observed between these two species (mean similarity =  0.36%). This low similarity is consistent with their geographical distribution.  According to the results of cluster and PCA analyses, the two species  completely separated from each other. These markers will aid in the  identification of elite genotypes for domestication and breeding programs.
