Present study was undertaken to broaden the genetic base in Brassica carinata cv. PC 5 for seed quality traits through induced mutagenesis. Mutagenesis with 0.5 per cent ethyl methane sulphonate followed by selfing in M1 and screening for fatty acid composition through half seed method in M2 and M3 generations led to the identification of stable M4 progenies having desirable fatty acid profile. One of the progeny EMS 9-56 appeared especially promising as it had about 24 percent erucic acid, 30 per cent oleic acid, and 40 percent oil content as against corresponding values of 46 percent, 11 percent and 34.2 percent in base variety, PC 5. Increase in oil content to 40.6 per cent was a significant achievement of the study as B. carinata germplasm lacks variability for this important trait.
