Abstract

                                Studies on different genetic parameters namely, genotypic and phenotypic variances, genetic coefficient of variation (GCV), phenotypic coefficient of variation (PCV), haritability and genetic advance were conducted on 112 exotic genotypes of green gram Vigna radiata (L.) Wilczek). High estimates of genotypic variances were recorded only for plant height and number of pods per plant. High estimates of heritability along with high genetic advance and GCV values were observed for the plant height. number of pods per plant, seed yield per plant, number of clusters per plant, number of secondary branches per plant and number of primary branches per plant, days to 50 per cent flowering and days to maturity exhibited low estimates of genetic advance. Seed yield per plant was associated significantly with almost all the yield attributing characters, indicating that selection for these characters will help in identifying high yielding varieties of green gram.
