Kernels from a barley line, 'Sultan-5', with powdery mildew resistance gene Ml-a12 were treated with mutagens. Among 10 381 M1 spikes progeny tested with Ml-a12 avirulent powdery mildew, 25 segregated mutants with infection types between 0–1 n and 3–4cn. The resistance of the mutants is race specific in the sense that it is expressed only with powdery mildew cultures that are Ml-a12 avirulent but not with an Ml-a12 virulent culture. Genetic analysis of 10 mutants revealed that 9 had mutant… CONTINUE READING
