Seeds contain phytochemicals with antioxidant and anti-flatulent properties. Till now, no cultivars have been introduced in the country. Getting an information about genetic diversity extent is a perquisite of any breeding program. In this study, ten SCoT primers were used to assess genetic diversity of 49 endemic varieties from different areas of Iran including nine provinces. Totally, 48 bands were amplified of which 41 were polymorphic resulting in a polymorphism frequency of 62.03% and an average of 5.1 polymorphic bands per primer. Out of nine primers, one primer (SCoT26) had no polymorphic band and one primer was not amplified. The size of bands varied between 250-3000 bp. Dendrogram was gained using Centroid Linkage and revealed five main clusters. Each cluster was subdivided into subgroups. The farthest genetic distance demonstrated among Esfahan-Feridoon and Northern Khorasan-Shirvan ecotypes and shortest revealed among Northern Khorasan-Esfarayen and Northern Khorasan-Maneh. According to Shannon-Weaver and Nie diversity indices, Kerman population have the maximum within population diversity and Semnan population have the minimum within population diversity. Fst and Nm amounts indicating high level of gene flow among nine Iranian cumin populations. Due to values of heterozygosity of subpopulations (Hs), total heterozygosity (Ht), there is more diversity among populations than diversity of within populations. Analysis of molecular variance within and among populations (AMOVA) evaluated. The present investigation revealed that significant genetic variations present among different ecotypes that could be successfully utilized in cumin breeding programs.
