Characterization and analysis of genetic diversity in Indian Sesame (Sesamum Indicum L.) genotypes

Abstract

Limited information is available on the extent of genetic variability in sesame. In this study, twenty phenotypic (qualitative and quantitative) traits and 200 RAPD markers were used to determine the extent of genetic diversity among 60 sesame varieties grown in different geographical regions of India. Fourteen RAPD markers were found useful in assessing the diversity. A high level of genetic variability among population (HT = 0.1991) and less variability within population (HS = 0.0749) was observed. Mean coefficient of gene differentiation (GST = 0.6238) was 62.38 % among sesame population and 37.62% within population. The study indicated that the Indian sesame lines are genetically diverse, which should be utilized in the improvement of sesame crop.
