Genetic variability and character association studies in sesame (Sesamum indicum L.)

Genetic variability, character association and path analysis between yield and its contributing traits were studied in 28 sesame genotypes. Analysis of variance revealed the existence of significant differences among genotypes for all the characters studied. Seed yield per plot, capsules per plant and primary branches per plant showed high phenotypic and genotypic coefficients of variation coupled with high to moderate heritability and high genetic advance indicating the predominance of additive gene effects in controlling these traits. Seed yield per plot showed significantly positive correlations with all the traits studied. Path coefficient analysis indicated that plant height and capsules per plant were important traits to be considered for realizing improvement in seed yield.
