Abstract:
Thirty white seeded sesame genotypes were evaluated in a Randomized Block Design (RBD) at the ORARS, Kayamkulam, during 2019-2020 to determine genetic variability, heritability and genetic advance for twelve biometric and quality characters. Analysis of variance showed that significant variation was present in the germplasm for the characters studied. The phenotypic coefficient of variation was found to be higher than the genotypic coefficient of variation for all the traits. High level of GCV and PCV was recorded in seed yield per plant followed by primary branches per plant, number of capsule leaf per axil, and number of capsules per plant. Heritability was high for all the characters except days to maturity (49.48%) which possessed only moderate heritability. GA (% mean) was high for all the characters except 1000 seed weight, days to 50% flowering, capsule length (cm), protein content (%), oil content (%) and days to maturity. High heritability coupled with high genetic advance as per cent of mean was recorded for seed yield per plant, number of capsule leaf per axil, number of capsules per plant, primary branches per plant, number of seeds per capsule and plant height.
