The study was conducted to evaluate genetic variability and trait association of yield and yield related traits in 5x5 simple lattice design during 2019 main cropping season. The analysis of variance showed highly significant differences (P<0.01) among the genotypes for all quantitative traits except days to maturity and biomass yield per hectare. Days to flowering, plant height and capsule length showed low Phenotypic and Genotypic Coefficient of Variations and genetic advance percent mean. Branches per plant showed medium Phenotypic and Genotypic Coefficient of Variations, heritability and genetic advance percent mean. Capsule per plant, seed yield per plant and seed yield per hectare showed moderate Phenotypic and Genotypic Coefficient of Variations and high heritability with genetic advance percent mean. Biomass yield per plant and harvest index showed high Phenotypic and Genotypic Coefficient of Variations, heritability and genetic advance percent mean. Both phenotypic and genotypic correlation coefficient analyses showed positive and significant association of seed yield with seed yield per plant and harvest index. Generally, this study painted the presence of significant genetic variation among tested sesame genotypes and the possibility to get genetic progresses in the succeeding breeding generations.
