Abstract: Homogeneous seeds of Oriental mustard cv. Agati Sarhein (Brassica juncea Coss.) were treated with different doses of gamma rays (750 to 1250 Gy) to induced genetic variability for the selection of genotypes with improved agronomic traits. Seventy-five useful mutants selected from M₂ generation were tested in progeny rows to confirm the stability of genetically altered economic traits in M₃ generation. Thirteen mutants with promising performance for yield and yield components were evaluated in preliminary yield trial. Five mutants produced significantly (P<0.05) higher yield than parent.
