Abstract:
The present investigation was conducted to estimate the extent of genetic variability, heritability, genetic advance. The experimental material comprising of 26 genotypes were evaluated at Oilseeds Research Station, Latur during kharif-2022. The material was sown in randomized block design with three replications, on 25^th June, 2022, observations were recorded for nine characters. Mean sum of square of genotype revealed highly significant for most of the characters under study which show the presence of sufficient amount of variability among the germplasm lines (experimental material) and hence provide an opportunity to improve the character through selection. A wide range of mean values among the genotypes for different characters i.e., plant height, days to maturity, number of branches per plant, number of pods per plant, showed presence of high amount of variability among the genotypes and offer the scope for different yield contributing characters improvement in soybean. The estimates of GCV and PCV were recorded high for number of pods per plant, number of branches per plant, number of pod per cluster and seed yield per plant. Higher heritability estimates were observed for all the traits under the study. However, high genetic advance as percent of mean was noted for characters like number of pods per plant, days to 50% flowering, days to maturity, number of branches per plant, seed yield per plant, plant height number of pod per cluster and low to moderate for 100 seed weight, oil content.
