Genetic divergence of 100 sesame (Sesamum indicum L.) advanced breeding lines was assessed using Mahalanobis's D2 method and the lines were grouped into 12 clusters. Cluster-I was the biggest with 76 genotypes followed by cluster-III with 14 genotypes. Ten clusters (Cluster II, IV, V, VI, VII, VIII, IX, X, XI, XII) were solitary in nature. The intra cluster distance was maximum in cluster-III though it had only 14 entries, cluster-I was lowest despite 76 entries. Inter cluster distance was maximum between cluster-III and cluster-XII. The cluster means estimated for 11 traits revealed that the cluster-VI recorded lowest and cluster-IV registered highest mean values for most of the characters studied. Distance from ground to first capsule contributed maximum (54 %) to divergence followed by days to 50 per cent flowering (18 %), number of capsules per plant (7 %), days to maturity, indicated that distance of capsule bearing from ground alone trait could explain ≈ 55 per cent of variation. These traits can be utilized for future crop improvement program.
