Abstract
Sesame (Sesamum indicum L.) is one of the most important oilseed crops of the world, particularly tropical areas. Its production issignificantly affected by drought stress. The present study was performed to assess the efficiency of existing criteria for the selectionof tolerant cultivars while evaluating sesame genotypes under drought conditions. Various agro-morphological traits along with somedrought tolerance indices were used to evaluate 15 sesame genotypes under drought conditions. A moderate to high heritability wasestimated for plant height (0.55), no. of capsules (0.72), capsule diameter (0.60), no. of seeds per capsule (0.43) and seed yield (0.53).On average, the seed yield of genotypes was reduced by 45% under water stress. Seed yield was significantly positively correlatedwith the no. of capsules, capsule diameter, and no. of seeds per capsule under both normal and drought conditions. The number ofcapsules and capsule diameter were suggested as potential criteria for indirect yield selection under drought stress. Chinese (G01), Naz Chand Shakhe (G05), and Darab1 (G04) genotypes were identified as the most tolerant based on the average ranking of indices. Stress/non-stress production index (SNPI), yield index (YI), and drought resistance index (DI) were suggested as the most efficient drought tolerance indices according to principal component analysis and correlations. The evaluation criteria proposed in this study can be used for efficient selection of drought-tolerant genotypes in sesame. Moreover, reported tolerant and sensitive genotypes can be used in future studies and breeding programs in sesame under drought stress.
