The aim of the present study is to characterize eight hundred twenty nine germplasm of sesame and identify the candidate genotypes from indigenous gene-pool of Sesamum indicum L. The experiment was executed at Project Coordinating Unit (Sesame and Niger) Research Farm, JNKVV, Jabalpur (M.P.) in unreplicated Augmented Block Design using 17 attributing characters. A significant amount of variation was observed for most of the traits studied. Study of growth traits clearly revealed that majority of the genotypes showed variability for growth habit towards semi-erect types and sparse hairiness on stem with majority of basal branching pattern. Towards leaf characters, higher frequency of sparse hairiness, ovate leaf shape for middle leaves, linear leaf shape for top leaves, entire basal leaf margin, absence of lobe incision of basal leaf and medium leaf size for leaf characters was observed in the study. Regarding colour traits, most of germplasm exhibited white with pink shading of corolla colour. Dense type corolla hairiness was in majority. Similarly, four number of locules/capsule, one flower/leaf axil, narrow oblong bicarpellate capsule shape, monocapsular arrangement, strong type of capsule hairiness, short capsule beak and straw/yellow colour of dry capsule for capsule characters also in higher frequency. Above study revealed the distinct characteristics of germplasm and indicated that morphological variations exist in collected germplasm due to variation in genetic makeup and could be better utilized by breeders in the selection based on their specific requirement for breeding programme along with that this is highly useful to study for varietal identification and conservation. Further, the unique featured lines can be selected for developing varieties with unique identification.
