A historical review of hybrid rice breeding
ABSTRACTThe development of germplasm resources and advances in breeding methods have led to steady increases in yield and quality of rice (Oryza sativa L.). Three milestones in the recent history of rice breeding have contributed to these increases: dwarf rice breeding, hybrid rice breeding, and super rice breeding.

Research and development of hybrid rice in China
In the past 60 years, China's hybrid rice has developed from a three‐line system to a two‐line system: This has enriched the knowledge of heterosis and crop breeding.

Hybrid Vigour and Hybrid Mimics in Japonica Rice
In crop improvement programs, hybrid vigour (heterosis) is an important breeding strategy but the molecular mechanisms of hybrid vigour are still unclear. Grain yield declines after F1 generation due to phenotypic segregation. We found that, at the early seedling stage in hybrids derived from the temperate japonica rice varieties ‘Doongara’ and ‘Reiziq’

The Next Generation of Rice: Inter-Subspecific Indica-Japonica Hybrid Rice
Rice (Oryza sativa) is an important food crop and has two subspecies, indica and japonica. Since the last century, four generations of rice varieties have been applied to rice production.
