| 摘 要： | 【目的】对水稻恢复系187R的18个重组自交系进行亲和性测定,为选配水稻新品种（组合）提供依据。【方法】利用籼稻天B、粳稻白R56和辽粳224作为测验种,分别与187R的18个重组自交系杂交,考察分析杂交F1小穗结实率。【结果】对天B、白R56和辽粳224均表现较高亲和力的自交系有WC26、WC69、WC187、WC209、WC217、WC219、WC246,属于中间型,具有一定广亲和性;对籼稻天B有特殊亲和力的重组自交系有WC65、WC70、WC191、WC203、WC225、WC228、WC350、WC373,表现亲籼性;对粳稻有特殊亲和力的重组自交系有WC22和WC25,表现亲粳性。【结论】具有广亲和特性的重组自交系可作为研究材料和育种材料,有较高利用价值;而具有亲粳性和亲籼性的重组自交系可作为育种中间材料或与粳或籼稻配组,筛选出优势强的组合用于水稻生产。

| Abstract: | Objective]The compatibility of 18 recombination inbred lines(IRLs) of rice restore line 187R were tested to provide a basis for breeding new rice variety(combination) .Method]The seed setting rate of spikelet in hybrid F1 of 18 IRLs crossed with tester viz.,Tian B(Indica) ,Bai R56 and Liaojing 224(Japonica) were investigated.Result]The RILs including WC26,WC69,WC187,WC209,WC217,WC219 and WC246 were wide-compatible and middle type,which showed higher compatibility to all testers.WC22 and WC25 showed speci... |
