KEYWORDS: Coefficient of variation, Correlation coefficient, Genetic Advance, heritability, Sesame selection.


Genetic variability of seven yield related traits were estimated including broad sense heritability for 19 genotypes of sesame. The agronomic traits studied were plant height. days to 50% flowering, number of branches/plant, number of capsules/plant, capsule length, seeds/capsule and dry grain yield. All the characters investigated showed high estimate of heritability except capsule length. The heritability values recorded were 94%, 96%, and 72% with corresponding high genetic advance for number of branches/plant. number of capsule/plant and seed yields respectively. These were regarded as indicators for effective selection. Seed yield was positively correlated to number of days to 50% flowering, seeds/capsule and number of capsule/plant at genotypic level with correlation coefficient (r) of 0.37, 0.23, and 0.25 respectively. On the other hand, plant height and number of branches significantly correlated with seed yield at phenotypic level. This maybe attributed to environmental influence. Considerable progress Is therefore expected in sesame seed improvement when these characters with positive correlation are considered inchoosing selection criteria.
