When grain of two varieties was subjected to 20, 30 and 40 kR gamma rays or 0.05, 0.07 and 0.10% EMS, the lowest radiation dosage was most effective with respect to the production of chlorophyll mutations in the M2, while the lowest concentration of EMS was most effective in the variety 148; in the variety RCR408, mutagenic effectiveness increased with EMS concentration. With respect to viable mutations, 20 and 30 kR gamma rays and 0.05% EMS were the most effective.
