Abstract:

The present study was carried out 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) for 12 quantitative traits of soybean (Glycine max L). Experimental material of the investigation comprised of 120 genotypes along with 5 checks. During analysis of variance, days to 50% flowering, number of nodes per plant, number of pod clusters per plant, and 100 seed weight showed highly significant difference among check varieties. The PCV and GCV values ranged between 40.33% and 30.07% for number of branches per plant and 5.34% and 5.05% for days to maturity respectively. Highest heritability was observed for 100 seed weight (99%) and lowest heritability was observed for harvest index (22.6%). Expected genetic advance as percent of mean ranged from 88.63 (number of nodes per plant) to 5.12 (harvest index %). High heritability coupled with high genetic advance as percent of mean was observed for days to 50% flowering, plant height, number of branches per plant, number of nodes per plant, number of pod clusters per plant, number of pods per plant, 100 seed weight, dry matter weight per plant, seed yield per plant. It can be concluded that these characters may be used as selection tool in future breeding programs.
