Abstract:
The aim of the present study was to characterize 457 germplasm accessions of sesame (Sesamum indicum L.) based on the DUS morphological descriptors. The experiment was conducted in augmented Design without replications at AICRP on Sesame and Niger, MARS, UAS, Dharwad during Summer 2017. On the basis of DUS descriptors, sesame accessions were characterized for eighteen morphological traits. Maximum amount of variation was observed for most of the traits studied. On the basis of frequency distribution, majority of sesame accessions were found to possess determinate plant growth type (56.9%), erect plant growth habit (49.5%), sparse stem hairiness (61.9%), basal branching pattern (53.6%), weak leaf hairiness (42.2%), entire basal leaf margin (43.3%), no lobe incision of basal leaf (38.9%), one flower per leaf axil (58.6%), sparse corolla hairiness (45.3%), white exterior corolla colour (40.0%) and white interior corolla colour (43.5%), four locules per capsule (96.9%), narrow oblong bicarpellate capsule shape (44.0%), monocapsular capsule arrangement (90.6%), weak capsule hairiness (53.4%), brown/tan colour of dry capsule (61.9%), long capsule beak (30.9%) and beige seed coat colour (22.1%). Present study revealed the distinctness in characteristics among sesame accessions.
