Yuan Longping's main achievements:

/kloc-0 began to study hybrid rice in 1964, and/kloc-0 cultivated miracle rice (IR8) in Yuan Longping, IRRI Philippine International Rice Research Institute in 1966. 1974 bred the first hybrid rice combination Nanyou 2.

1975 hybrid rice seed production technology was successfully developed, which laid the foundation for large-scale popularization of hybrid rice. 1985 put forward the strategic idea of hybrid rice breeding, and pointed out the direction for the further development of hybrid rice.

1986, Yuan Longping put forward the hybrid rice breeding strategy, which divided the hybrid rice breeding method into three strategic development stages: three-line method, two-line method and one-line method, that is, the breeding program developed from complex to simple and efficient; The utilization of heterosis level can be divided into three strategic development stages: interspecific heterosis utilization, interspecific heterosis utilization and distant heterosis utilization.

That is to say, the advantage utilization is developing in a stronger and stronger direction. According to this idea, every time hybrid rice enters a new stage, it is a new breakthrough, which will promote rice production in by going up one flight of stairs. This strategic concept points out the direction for China to explore new hybrid rice after the successful research and development of three-line hybrid rice.

1On July 6th, 987, Yuan Longping students Li Bihu and Deng Huafeng discovered a photosensitive sterile rice in the three-line indica rice breeding materials of Anjiang Agricultural School. After two years and three generations of propagation and observation in different places, the agronomic characters of this material are neat and consistent, the sterile plant rate and sterility degree reach 100%, and the fertility transformation is obvious and synchronous.

This new achievement has opened up a new situation for the transition of hybrid rice from "three-line method" to "two-line method" In the same year, he put forward the "development strategy of hybrid rice", that is, using heterosis among plants on the basis of three-line method; Utilization of heterosis between indica and japonica subspecies based on two-line method: utilization of distant heterosis based on one-line method.
