Evaluation of Genetic Diversity of Aegilops Tauschii from Northern Area of Iran Using SSR Markers

In this study، in order to study genetic diversity in the accessions of Aegilops tauschii from Northern area of Iran، 86 accessions of this species selected and evaluated using SSR markers. Ten SSR primer pairs were applied for genotyping assays. A total of 140 alleles were detected across all loci، ranging from 9 to 25 alleles per locus، with an average of 15. 5 alleles per locus. The polymorphic information content (PIC) values of the loci ranged from 0. 16 (WMS111) to 0. 38 (WMS114). Genetic similarity calculated from the SSR data ranging from 0 (many genotypes) to 0. 88 (two genotypes from Ghazvin and Gilan) with an average of 0. 101. Cluster and PCA analyses could not separate accessions، indicating that there is high genetic diversity among accessions.
