The frequency and spectrum of M/sub 2/-chlorophyll mutations, after EMS or gamma ray seed treatments in two pea varieties were studied. Irrespective of the method of calculation, EMS was found to be highly superior to gamma rays in inducing a higher frequency and a wider spectmm of mutations. The superiority factor was 8 to 9 for mutation frequency and about 4 for the percentage of M/sub 2/-families segregating chlorophyll mutants, ' or for the mean number of mutations per M/sub 2/-family. At higher mutagen doses, the mutation rate declined. No change in mutation spectmm was found on changing the mutagen dosage. No varietal differences could be detected. (auth)
