Mutagenic effects of gamma rays and EMS using both single and combined dosages were examined in opium poppy ( Papaver somniferum L.). For inducing both macro‐ and micro‐mutations in the present study, combined mutagenic doses, especially 5 kR + 0.4 % EMS appeared to be greatly superior to all single doses of the two mutagens: gamma rays and EMS. The lowest dose of combined mutagen (5 kR + 0.2 % EMS) was about twenty times more effective than the most effective dose (15 kR) of gamma rays and twice as effective as the most effective concentration (0.4 %) of EMS. The combined dose 5 kR + 0.4 % EMS enhanced morphine content (%) to 0.98 as against 0.64 in the control. In accordance with earlier findings (GAUL 1964) the study revealed a correlation between induced macro‐ and micro‐mutations.
