本研究的材料是用珍汕97(野败)A与恢复系配制成的2个籼稻杂种。其F_1可育,具有正常的可染花粉率,F_2育性分离比率为3:1,表明该育性恢复行为发生在孢子体时期,并至少具有一对显性基因。育性恢复与内、外颖颜色基因连锁,其交换值为9.7—27.1％。在黎明(rufipgon)A/IR5032—6B—13—1的回交一代及F_5代中,未发现对黎明A细胞质雄性不育具有恢复能力的Rf单株或株系。该组合的F_1是可育的。将其F_5代株系与珍汕97A测交,出现不同的育性恢复度,其中包括完全恢复。
The material of this study was two indica hybrids made from Zhenshan 97 (wild defeated) A and restorer lines. F_1 was fertile and had a normal rate of dyeable pollen. The F 2 fertility segregation ratio was 3: 1, indicating that fertility restoration occurred in the sporophytic period and had at least one pair of dominant genes. Fertility restoration and internal and external Ying color gene chain, the exchange value of 9.7-27.1%. In the backcross generation and F_5 generation of rufipgon A / IR5032-6B-13-1, no single Rf plant or strain was found that had the ability to restore the damaging A-cytoplasmic male sterility. F_1 of this combination is fertile. The F_5 generation strains and Zhenshan 97A measured cross, there are different degrees of fertility restoration, including the complete recovery.
