| 摘 要： | 对水稻细菌性条斑病表现高抗的 Dular、IR26、IR36和IR1545-339 等4个籼稻品种与感病品种金刚30杂交并分别与双亲回交，获得F1、F2、BC1和BC2。在隔离网室用细菌性条斑病菌株RS-68接种不同世代群体，根据其抗感反应推断：IR36的抗病性是由一对隐性主效基因控制的，Dular、 IR26和IR1545-339三个品种的抗病性分别由一对显性基因控制，Dular和IR1545 339的抗病基因呈非等位关系

| Abstract: | The inheritance of resistance to the strain RS-68 of Xanthomonas oryzae pv. oryzicola in four indica rice cultivars (Dular, IR26, IR36 and IR1545-339) were studied. Based on the analysis of population variations in lesion length in hybrids including F1,F2,BC1 and BC2 derived from four combinations by those resistant cultivars with a susceptible cultivar Jingang 30. It was found that the resistance of Dular, IR26 and IR1545-339 to the pathogen wes respectively controlled by one pair of dominant genes, and the resistance of IR36 was controlled by a recessive gene. |
