Variability, Heritability and Genetic Advance Of Yield and Yield Attributing Traits over different Environments in Sesamum (Sesamum indicum L.)

An investigation was carried out to assess the variability, heritability and genetic advance for nine quantitative characters in 10 genotypes over six environments during Kharif, 2010 and Rabi 2010–11. Significant differences were observed for all the characters among the genotypes studied over environments. The results revealed that high GCV and PCV were observed for the characters viz., seed yield per plant, number of capsules per plant, number of primaries per plant and number of secondaries per plant in all the environments studied. The characters seed yield per plant, number of secondaries, number of capsules per plant and number of seeds per capsule had shown high heritability accompanied by high genetic advance over environments. The traits number of capsules per plant, numbers of seeds per capsule, seed yield per plant, number of primaries and number of secondaries are found little influenced by environment.
