Description

Rice F0 seeds were treated with 10 krad of 60Co γ-rays, and blast resistance mutant R917 was selected in the following generations. The blast resistance was tested by inoculating the mutant with 138 strains of Piricularia oryzae artificially from nine blast regions in Zhejiang Province, scale of blast resistance was only 0.89 and 1.0 in 1991 and 1992 respectively. The rice mutant R917 was resistant to 136 blast fungus strains. The rate of blast resistance for R917 was higher than that of its parents. The mutant is likely to be used in rice breeding for variety improvement
