Greengram (Vigna radiata (L.) Wilczek) is legume crop cultivating throughout the year, which is amicable for all kinds of environment. The MYMV incidence and low harvest index leading to low yield. Genetic variability parameters were studied in 100 greengram genotypes raised during kharif 2013 in randomised block design with two replications. Observations were made for eighteen biometrical traits. The estimates of PCV (Phenotypic coefficient varience) were higher than GCV (Genotypic coefficient variance) for all the characters. The maximum phenotypic and genotypic variance was observed for the character dry matter production and length of branch. The estimates of phenotypic and genotypic co efficient revealed that maximum variation in dry matter production and number of clusters per branch respectively. The maximum heritability estimate was registered in maturity related trait days to full maturity (97.85), For morphological traits namely plant height (81.32) was high. The protein content recorded heritability was medium. The lowest heritability of percent was registered for dry matter production. The genetic advance for the trait plant height is high. The highest genetic advance expressed as percentage of mean was recorded by number of clusters per branch These characters were consider for parental use to create new variation for the future generation.
