| Abstract: | Looking back at the history of rice breeding, two breakthroughs resulted largely from identification and utilization of dwarfing genes in 1960s and the wild abortive cytoplasmic male sterility (CMS) in 1970s had significantly raised rice yield potential. But the yield potential of both inbred and hy |
