A set of sesame genotypes including popular ruling varieties was characterized for genetic diversity based on 14 agro-economic traits including seed yield. The test genotypes were separated into six genotypic groups based on Euclidian genetic distance following SAS software programme. Cluster IV genotypes (TC 25 and RT 103) had shown dwarf plant type along with capsule bearing from lower height indicating possibility of more scope for increased number of capsules/plant. Cluster I (Pratap) bore longer and bold capsule resulting highest number of seeds/capsule coupled with increased 500-seed weight. Besides, Pratap maintained very high degree of genetic divergence with most of the test genotypes and it happens to be maximum with B67 followed by RT 103, TC 25, BS 5-18-6, T 13 and TMV5. Inter se crossing of Pratap with any of the above genotypes may result heterotic performance in F1 and pave the way for possible recovery of transgressive segregants in the follow-up selfing generations.
