Abstract
Sesame (Sesamum indicum L.) is an important oilseed crop with high-quality seed oil and richness inantioxidant substances. The genetic relationship analysis of sesame is inportant for genetic conservation and exploration. In this research, we reportedthe results on analysis of genetic diversity of 56 sesame accessions by using DNA markers. Among 15 markers (10 SSR and 5 SRAP markers)used,3 were monomorphic and 12 were polymorphic with a total of 34 allelesand an average of 2.3 alleles per locus. The proportion of polymorphic bandsranged from 66.7 to 100% and reached 80.9% on average. Genetic similarity coefficient of 56 sesame accessionsranged from 0.52 to 0.97. At 0.70 similarity, 56 accessionswere divided into 7 groups, the largest group with 35 accessions, followed by group 2 with 17 accessions.
