2. The basic idea and technology of hybrid rice, as well as its first successful realization, were completed by American Henry Beach in 1963 in Indonesia. Henry Beach is also called the father of hybrid rice by some scholars, and/kloc-0 won the World Food Prize in 1996. Because of some defects in Henry Beach's ideas and schemes, it is impossible to popularize them on a large scale.
3. Yuan Longping was transferred to Hunan Academy of Agricultural Sciences in February of 197 1, specializing in hybrid rice research. 1973, the scientific and technological research team headed by him completed the three-line matching, successfully cultivated hybrid rice, and achieved a historic breakthrough in hybrid rice. 1997 put forward the technical route of "super-high-yield breeding of hybrid rice", which attracted great attention internationally.
Under his leadership, in 2000, 2004, 20 1 1 year, the first, second and third phases of super rice yield of 700 kg, 800 kg and 900 kg per mu were realized, and in 20 1438, the super rice yield per mu was also realized. Known as the father of hybrid rice.

Yuan Longping's main contribution
1, Yuan Longping took the lead in the research on the utilization of rice heterosis in China. In his first paper, Rice Male Sterility, he proposed: "If you want to take advantage of rice heterosis, you must first take advantage of male sterility". His theory and research practice are a challenge to the classical genetic theory, denying the traditional view that "self-pollinated crops have no heterosis" and greatly enriching the theory and technology of crop genetics and breeding.
2. Yuan Longping put forward the development strategy of hybrid rice breeding, that is, from three lines to two lines and then to one line, the procedure is more and more simple and the efficiency is higher and higher; At the level of heterosis, from varieties to subspecies to the utilization of distant heterosis, heterosis is getting stronger and stronger, which pushes hybrid rice to a new level step by step. This idea has been adopted by colleagues at home and abroad and has become the guiding ideology for developing hybrid rice breeding.
