Abstract
Cuminum cyminum (as an aromatic herb) is the sources of cumin, which has been commonly used in traditional medicine for the treatment of various diseases especially in tropical Asia. Thus, the current experiment was performed to accesses molecular genetic diversity among 22 collected accessions of cumin from different area of Iran, based on inter simple sequence repeat (ISSR) markers and start codon targeted (SCoT) markers. Analysis of molecular variance revealed that a significant genetic difference between the studied accessions reach to 43%. Mantel test between genetic diversity and geographical distance indicated that an increase in geographical distance of collected accessions did not influence on genetic differentiation. Results about all agro-morphological traits showed a significant difference between the ecotypes except the number of branches. Canonical correspondence analysis ballot of genetic features and environmental factors included 5 geographic and climatic factors for seed origin’s habitat, which have been show that the mentioned parameters had no strong effect on the plant genotypes. However, difference in elevation and latitude of accession origins had effect on genetic clustering in two major groups. The consensus tree of both molecular and morphological data relieved that the accessions Chah-Dashi, Damghan, Ferdows and Nehbandan formed discreet clusters based on genetic and agro-morphological features. In conclusion, the results confirmed that both ISSR and SCoT markers were reliable and useful tools for analyzing the genetic diversity of cumin in Iran.
