Yuan Longping's life story

Yuan Longping, male, Han nationality,/kloc-0 was born in Beijing on September 7th, 930.

1953 Graduated from Southwest Agricultural College.

1964 began to study hybrid rice.

1973 realizes triple matching.

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.

1987 Served as the expert in charge of two-line hybrid rice in the 863 Program.

1995 two-line hybrid rice was successfully developed. In the same year, he was elected as an academician of China Academy of Engineering.

1997 put forward the technical route of super hybrid rice breeding.

In 2000, the first stage of super rice breeding in China was realized.

In 2004, the second phase of super rice was realized one year ahead of schedule. He has successively won many domestic awards such as the National Special Invention Award and the First Highest Science and Technology Award, and 1 1 international awards such as the United Nations Science Award, the Wolf Award and the World Food Award.

Yuan Longping solved three difficult problems in the research of three-line hybrid rice.

Firstly, the technical scheme of "distant hybridization between wild rice and cultivated rice" was put forward, and finally an effective way to cultivate male sterile lines was found. 1973 realized the "three lines" of sterile line, maintainer line and restorer line.

Second, a number of combinations such as "Nanyou No.2", a hybrid rice with strong advantages, were bred and widely used in production, becoming the first scientist in the world to successfully utilize the heterosis of rice.

The third is to break through the seed production barrier. According to previous studies, the outcrossing rate of rice is only 2.4%, and the seed yield of hybrid generation is extremely low, which is far from meeting the production requirements. The International Rice Research Institute started research on 197 1 and gave up on 1973, because no one in the institute believed that it could solve the problem of seed production at that time. The research group led by Yuan Longping successfully solved this problem, and the seed yield gradually increased, and now the yield per mu has reached more than 300 kilograms.
