Abstract

Pure line mutants from the mutation pools of the TNG67 rice variety derived from seed mutagenesis using sodium azide were subjected to brown planthopper (BPH) challenge by the bulk-seedling method. About 9.6%－12.5%, 3.4%, and 7.7% of the mutants from the first mutation pool showed resistance (score < 3) to Race 1, Race 2, and Race 3 of BPH, respectively. Among them, 6 mutants (SA0006, SA0038, SA0080, SA0088, SA0159, and SA0283) were resistant to all races of BPH tested. In the second mutation pool, about 19.2%－26.0% of mutants showed resistance to BPH Race 1. Our experiments demonstrated that sodium azide produced a significant mutagenesis effect on inducing resistance to TNG67, a BPH-susceptible variety, at a rather high rate.
