Abstract:

The evaluation of phenotypic variability, heritability, genetic advance and diversity in germplasm collections is important for both plant breeders and germplasm curators to optimize the use of the variability available. In the present study, Thirteen sesame genotypes were grown during Rabi Summer’2019 at Agricultural College and Research Institute, Kudumiyanmalai (TNAU) taken to assess genotypic, phenotypic variability and heritability coupled with genetic advance. The biometrical and morphological traits such as days to fifty percent flowering, plant height, number of branches, number of capsules per plant, seeds per capsule, thousand seed weight, seed yield per plant and plot yield. The GCV and PCV estimates were found to be high for seed yield per plant, number of capsules per plant and number of branches per plant. High heritability coupled with high genetic advance was observed for the characters seed yield per plant, number of seeds per capsule, number of capsules per plant, number of primary branches per plant and plant height. This indicated the additive genes governed these traits and the improvement could be brought about by selection for these traits. Therefore, these characters can be considered as a criterion for improving seed yield in breeding programs of sesame.
