| Abstract: | About 25,000 M2 and M3 seedlings of the bread wheat variety C. 591 were tested for resistance to 3 races of stem rust. A mutant with resistance to race 40 of stem rust was found in a family derived from treatment with 16,000r of X-rays. No other mutant was found. Albina seedlings were found to be totally free of rust infection. From the present study it seems that mutations for rust resistance can be induced in bread wheat by ionizing radiations but the frequency of such mutations appears to be very low. |
