Abstract
Genotypic and phenotypic variation, heritability and genetic advance expressed as percentage of mean for yield and yield contributing traits were studied in 14 genotypes of mung bean (Vigna radiata L.). Genotypic and phenotypic variances were high for number of pods per plant (18.60 and 19.50) and days to maturity (16.39 and 17.69). Heritability was high for 100-seed weight (0.99) and lowest for seed yield per plant (0.42). High heritability with high genetic advance as percentage of mean for number of pods per plant showed the additive gene effect for these characters. Analysis of variance for parameters showed the significant variations for all variables under consideration. Genotype 8010 produced maximum number of pods per cluster (3.72) and number of pods per plant (27.33). Maximum plant height (41.23) was recorded for genotype 8003 while genotype 98002 took maximum days to flowering (49.66) and days to maturity (86.66). Similarly, maximum 100-seed weight (5.64) and seed yield per plant (13.76) were recorded in genotypes 8004 and 8002, respectively. Existing variation may helpful for selection and further hybridization breeding program in future.
