One hundred and four sesame genotypes were evaluated for genetic variability parameters using 18 traits during rabi 2023-24 in dry land farm of S.V. Agricultural College, Tirupati, Andhra Pradesh. Analysis of variance revealed significant differences among the genotypes for all the traits except for 1000 seed weight and capsule length. High estimates of genotypic coefficient of variability (GCV) and phenotypic coefficient of variability (PCV) were recorded for the traits number of secondary branches per plant followed by seed yield per plant and number of capsules per plant. Heritability studies revealed that all the traits except plant height, number of primary branches per plant and capsule length showed high heritability. High heritability coupled with high genetic advance was exhibited by number of secondary branches per plant, seed yield per plant, plant height to first capsule number of capsules per plant, and 1000 seed weight indicating the prevalence of additive gene action in their inheritance.
KEYWORDS: Genetic variability, genetic advance as percent of mean, heritability, sesame.
