对水稻细菌性条斑病表现高抗的两个籼稻品种IR36 和BJ1 与感病品种南农籼2 号、金刚30 和明恢63 等杂交并分别与双亲回交, 获得F1、F2、BC1、BC2 等世代。用条斑病菌株Rs105 接种不同世代群体, 根据其抗感反应推断: BJ1 对细菌性条斑病的抗性由一对显性基因控制, IR36 的抗性则由两对隐性基因控制。 Two indica rice varieties IR36 and BJ1 with high resistance to bacterial leaf streak of rice were crossed with susceptible varieties Nongnongxian 2, Jingang 30 and Minghui 63 respectively and backcrossed with their parents to obtain F1, F2, BC1, BC2 and other generations. Inoculated with different generations of the strain Strain Rs105, we deduced from the anti-susceptibility responses that the resistance of BJ1 to bacterial leaf streak was controlled by a pair of dominant genes while the resistance of IR36 was controlled by two pairs of recessive genes.
