| 摘 要： | 针对云南的立体稻作生态环境,导致了稻瘟病发病轻重及生理小种差异较大,对两系杂交稻抗瘟性要求较高,为此我们提出培育多系品种。以优良的两系杂交稻恢复系为公共轮回亲本,与多个抗源亲本杂交、回交,转育成具有不同抗性遗传背景的系列恢复系（简称多系）,再经测配筛选,配制出具有不同抗病基因的系列两系杂交组合应用于生产,实现抗性多样化。

| Abstract: | The diversified environment in Yunnan result in diversified blast races and serious rice blast damage in Yunnan province. It is necessary for two line hybrid rice to have wide resistance spectrum and strong resistance. So multiline breeding methed was used. The recurrent parent, with high yield, fine quality and restoring ability were crossing with different resistant donors. The new restore lineswhich have different resistances and were selected testing from backcross progenies. So as to breed for several two lines hybrid rice with different resistant genes. |
