Abstract
An experiment was conducted to assess genetic variability parameters with 45 genotypes of soybean [Glycine max (L.) Merrill] at Experimental Farm, Main Oilseeds Research Station, Junagadh Agricultural University, Junagadh during kharif-2024 in a randomized block design with three replications. High genotypic and phenotypic coefficient of variation were observed for seed yield per plant, followed by harvest index, biological yield per plant, number of pods per cluster and number of primary branches per plant. While the number of primary branches per plant, the number of pods per cluster, seed yield per plant, biological yield per plant, harvest index, the number of pods per plant, number of clusters per plant, number of seeds per pod and 100-seed weight exhibited high heritability along with moderate to high genetic advance as a percent of the mean.
