A historical review of hybrid rice breeding.

The development of germplasm resources and progress in breeding methods have led to steady increases in rice (Oryza sativa) yield and quality. Three milestones in the recent history of rice breeding have contributed to these increases: dwarf rice breeding, hybrid rice breeding, and super rice breeding. On the occasion of the 50th anniversary of the success of three-line hybrid rice, we highlight important scientific discoveries in rice breeding that were made by Chinese scientists and summarize the broader history of this field. In addition, we discuss the strategies that could be used in the future to further optimize rice breeding in the hope that China will continue to be a leader in the international rice breeding arena.
