Abstract:

Sesamum (Sesamum indicum L) is the most cultivated oil crop in India. It has great diversity across the Indian biota. The existing variability would be utilized for the commercial purpose of sesame. The purpose of the study is to evaluate the morphological characterization and variability available in the sesame genotypes available in Tamil Nadu. Fifteen sesame genotypes were grown during Rabi Summer 2018 at Agricultural College and Research Institute, Kudumiyanmalai (TNAU) for the estimation of genotypic and phenotypic coefficient of variation along with heritability and genetic advance. Eight biometrical and morphological traits were recorded for fifteen genotypes. High PCV and GCV are recorded for the traits viz., number of branches per plant, seed yield per plant and total number of capsules per plant. High heritability and genetic advance was observed for the characters number of branches per plant, number of capsules per plant, seed yield per plant, plant height, plot yield, 1000 seed weight and number of seeds per capsules. The traits with high heritability and high genetic advance as percent of mean are governed by the additive gene action where simple selection is effective for breeding programmes.
