| 摘 要： | 经四川农业大学水稻研究所良繁研究室发现，（G46A、D702A、珍汕97A）D 62A／红宝石的F1代，植株基本全不育，但在回交过程中育性发生分离，可育株数明显增多，猜想红宝石具有对G46A、D702A、珍汕97A和D62A育性恢复的特性。为了验证该猜想，笔者构建遗传群体对其恢复性进行分析，并用SSLP对红宝石的恢复基因加以定位。

| Abstract: | Objective] This study was to investigate the restoring ability of normal indica red rice Ruby and to carry out its restoring gene mapping. Method] Normal indica red rice Ruby was hybridized with the sterile lines Zhenxian 97A, D62A, G46A and D702A to prepare their F1, BC1 and F2 progenies, and the pollen fertilities of these progenies were investigated. Meanwhile the restoring genes were mapped using SSLP. Result] For the sterile lines tested, Ruby has a gene to restore their fertilities. This gene is located on the chromosome 7 and shows a genetic distance of 7.4 cM with RM182. Unlike the clustering distribution of the restoring genes on chromosome 10, it is a specific restoring gene. Conclusion] It is feasible to breed restoring genes controlling red color characters via transgene and backcross. |
