The present study was carried out in at N E Borlaug Crop Research Center , G B Pant University of Agriculture and Technology Pantnagar, Uttarakhand to estimate the genetic parameters such as genotypic coefficient of variance (GCV), phenotypic coefficient of variance (PCV), heritability (h2) and genetic advance as percent of mean (GAM) and inter-character association for 12 quantitative traits of soybean (Glycine max L) germplasm. Experimental material of the investigation comprised of 276 genotypes along with 4 checks. During analysis of variance, characters days to 50% flowering, days to maturity, plant height, number of nodes per plant, number of pods per plant, 100 seed weight, dry matter weight per plant, plant population per plot and harvest index (%) showed highly significant difference among check and significant difference showed for seed yield per plant. The PCV and GCV values ranged between 17.87% and 17.83% for plant population per plot and 4.75% and 2.62 for, days to 50% flowering and days to maturity, respectively. Highest heritability was observed for number of nodes per plant (99.86%) and lowest heritability was observed for seed yield per plant (62.20%). Genetic advance as percent of mean ranged from 36.66 (plant population per plot) to 4.62 (days to maturity). High heritability coupled with high genetic advance as percent of mean was observed for plant height, number of pods per plant, dry matter weight per plant, plant population per plot and harvest index %. It can be concluded that these characters may be used as selection tool in future breeding programs.
