Abstract: The resistance of rice variety RP1976-18-6-4-2 to the rice brown planthopper (BPH) and the rice gall midge (GM) was analyzed. RP1976-18-6-4-2 showed resistance to biotype Ⅱ, biotype Bangladesh of BPH and China type Ⅱ, China type Ⅳ of GM.Genetic analysis suggested that the resistance of RP1976-18-6-4-2 to biotype Ⅱand biotype Bangladesh of BPH were both controlled by a dominant gene and a recessive gene; and resistance to China type Ⅱ and China type Ⅳ of GM was controlled by a single dominant gene.

摘要： 对水稻品种RP1976-18-6-4-2进行褐飞虱和稻瘿蚊的抗性评价及其遗传分析。结果表明，该品种抗褐飞虱生物型Ⅱ、孟加拉型及稻瘿蚊中国Ⅱ型和中国Ⅳ型，它对褐飞虱生物型Ⅱ和孟加拉型的抗性由1对显性基因和1对隐性基因控制；对稻瘿蚊中国Ⅱ型和中国Ⅳ型的抗性由1对显性基因控制。
