Abstract:
Genetic variability, heritability and other related parameters of nine quantitative and qualitative characters were taken into account for study by growing thirteen diverse varieties of sesame (Sesamum indicum L.) including two (NC) and one zonal check varieties. The study was carried out agriculture research farm, Rajaula, MGCGV, Chitrakoot, Satna (M.P.) during the kharif season of session 2021-22. The experiment was laid out in randomized block design and the obtained data was subjected to statistical analysis by the means of analysis of variance (ANOVA). Analysis of variance or design of the experiment indicated highly significant differences among the genotypes for all the eight characters except 1000-seed weight. The phenotypic coefficient of variation was higher than the genotypic coefficients of variation. Maximum genotypic and phenotypic coefficient of variations were obtained for plant height, number of branches per plant, seed yield kg/ha, and number of seeds/capsule, conclusively indicating possibilities for making further improvement in these characters due to presence of high magnitude of genetic variability in the material for these characters. The minimum genotypic and phenotypic coefficients of variation were observed for 1000 seed- weight. The high heritability was expressed by plant height, seed yield (kg/ha), days to 50% flowering, oil content percentage, number of capsules/plant, 1000 seed weight, number of branches/plant, days to maturity and number of seed/capsule in the range of 75.30-99.50%. High to moderate estimates of expected genetic advance were found for all characters other than 1000 seed weight which showed low genetic advance. The direction for genotypic and phenotypic correlations was similar for almost all characters and in general, genotypic correlations were higher than phenotypic ones in magnitude for many characters.
