Mutagenic effectiveness and efficiency of gamma rays and EMS was studied based on biological injury (lethality and pollen sterility) in M generation and frequency of chlorophyll mutation in M generation. The 1 2 results showed presence of radina, chlorina, xantha and albino type of chlorophyll chimeras in linseed and with the maximum frequency of chimeras at 60 kR (0.490 %) gamma rays and 0.6 per cent EMS (0.476 %). No dose dependent relationship was observed for both effectiveness and efficiency and varied according to cultivars of linseed. However, the gamma rays doses were found more effective and efficient then EMS.
