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. | Study of variability and genetic parameters in soybean germplasm
