Abstract: Homogeneous seeds of Brassica juncea L. cv. S-9 were treated with different doses of gamma rays (750 and 1000 Gy) and EMS (0.75% and 1.0%) to induce genetic variability for the selection of genotypes with improved quantitative and quality traits. After passing through different stages of selection, 17 promising mutants were selected for further studies. Seventeen mutants and its parent were evaluated for yield and yield components in the preliminary yield trials for two consecutive years. Three mutants S 97-75/36, S 97-1.0E/20 and S 97-1.0E/21 were significantly (p 0.05) superior to all other entries in grain yield and these were also found early in maturity, short statured and having high seed index.
