Induced genetic variability for quantitative traits in M2 generation in soybean by mutagens

Abstract

The various genetic variability parameters were estimated using physical (gamma rays) and chemical (EMS) mutagens using two cultivars i.e. PKV-1 and JS-335. Results indicated that genotypic coefficient of variation and phenotypic coefficient of variation, heritability were significantly high for different characters studied i.e. Plant height, number of  branches per plant, number of  clusters per plant, number of  pods per plant, yield per plant, 100 grain weight. All the mutagenic treatments were effective in inducing genetic variability in both the varieties.
