摘　　要：水稻突变体Ｒ＿９１７是经辐射诱变育成的抗病性强、抗谱广的水稻突变新种质。经稻瘟病菌生理小种ＺＢ＿１５、ＺＣ＿１３和ＺＥ＿３测定，其抗性由一对显性基因控制。经与秀水１１、秀水８６１等品种杂交后代抗性分析，表明Ｒ＿９１７的抗性基因容易转育，是一个能广泛应用的育种材料。Rice mutant R917 with resistance to rice blast was selected by induced mutation with irra-diation, The F2 segregation of R917/NF6,XS11,XS861 crosses with resistance to rice blastZB15 ,ZC13,ZE3 showed that the rice blast resistance is controlled by one dominant gene. Theidentification of the disease resistance tor the progenies of R917 crosses with XS11, XS861showed that R917 could be used as a good material for resistance to rice blast in rice breeding.
