| Research Abstract |
F1 hybrid rice, which promises high yielding, has been planted in 12% of rice-cultivated area. For Fl hybrid rice breeding, cytoplasmic male sterility and fertility restoration system has been widely utilized. We analyzed the occurrence and restoration mechanism of three kinds of cytoplasmic male sterility in rice. Our finding provides new insights into the study of Fl hybrid breeding as well as reconciliation of a conflict between nuclear and mitochondrial genomes.
