Thirty six diverse genotypes of Indian mustard (Brassica juncea L. Czern and Coss.) were evaluated for ten quantitative. The variability indicates that Genotypic coefficient of variation (GCV) was moderate for 50% flowering, days to maturity, total no. of siliqua per plant, biological weight, test weight and seed yield; low for plant height, no. of siliqua on main shoot, no. of seed per siliqua and harvest index. The estimation of phenotypic coefficient of variation (PCV) was high for biological weight; moderate for all characters except no. of seed per siliqua, it has low PCV. high heritability was recorded for the character days to maturity (94.1%) followed by 50% flowering (92.4%) and Test weight (92.0%). The high heritability denotes high proportion of genetic effects in the determination of these characters and can be adopted for improving seed yield. Where as the low heritability was observed for the characters total number of siliqua per plant (48.7%), Plant height (43.8%), Number of seed per siliqua (39.8%), number of siliqua on main shoot (22.3%) biological Weight (17.9%) and Harvest Index (7.1%). Genetic advance as percentage of mean was observed high for the character is highest in days to 50% flowering (20.995%), days to maturity (21.320%), total no of siliqua per plant (20.066%) and test weight (35.936%). The value of genetic advance for plant height, no. of siliqua on main shoot, No. of seed per siliqua, biological weight, harvest index and seed yield are low. After studing such quantitative characters it was revealed that selection for number of test weight, total number of siliqua per plant, days to 50 % flowering and days to maturity would be effective for improvement of seed yield in this population.
