摘 要 ：8种不同胞质类型的不育系及其保持系与9个恢复系按P×Q交配设计分别配制不育系杂种和保持系杂种， 接种白叶枯病(Xoo)“强”致病力菌系ZHE-173和“弱”致病力菌系KS-6-6， 研究杂交稻抗白叶枯病的遗传机制。 结果表明： (1) 不育系或保持系、 恢复系以及不育系或保持系与恢复系间的互作对不育系杂种或保持系杂种抗性的影响均

Abstract:Eight different cytoplasmic male sterile lines and their corresponding maintainer lines were crossed with nine restoring lines harbouring dominant R-genes Xa-3, Xa-4, Xa-7 and Xa-21 respectively according to P×Q design. Male sterile line hybrids and maintainer line hybrids were inoculated with stro
