The study was carried out to assess the genetic variability and association of traits with respect to seed yield and its components in sesame genotypes. Seventy five sesame genotypes were grown during kharif 2016 at the Project Coordinating Unit Sesame and Niger, JNKVV, Jabalpur for the estimation of phenotypic and genotypic variances, heritability, genetic advances, correlation and path coefficient analysis for seed yield and yield related traits. High values for phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) was recorded for traits viz., number of secondary branches/plant followed by number of primary branches/plant, seed yield/plant, number of seeds/capsule, number of capsules/plant, transpiration rate, stomatal conductance, photosynthetic rate, chlorophyll content and days to flower initiation and hence improvement through selection of these traits could be possible. High heritability coupled with moderate genetic advance was recorded for oil content and days to 50% flowering. Thus, these traits are most likely controlled by additive gene action which is very useful in selection. Correlation and path analysis revealed that the characters viz., plant height, number of secondary branches/plant, number of seeds/capsule and oil content have positive direct association along with significant positive correlation with seed yield. Therefore, these characters can be considered as a criterion for improving seed yield in breeding programs of sesame.
