Yuan Longping, male, Han nationality, was born in Beijing on September 7, 193.
I graduated from Southwest Agricultural College in p>1953.
hybrid rice was studied in p>1964.
in p>1973, three-line matching was realized.
In p>1974, the first hybrid rice combination Nanyou 2 was bred.
In p>1975, hybrid rice seed production technology was successfully developed, which laid the foundation for large-scale popularization of hybrid rice.
the strategic idea of hybrid rice breeding was put forward in p>1985, which pointed out the direction for the further development of hybrid rice.
In p>1987, he served as the responsible expert for the special topic of two-line hybrid rice in the 863 plan.
two-line hybrid rice was successfully developed in p>1995. In the same year, he was elected as an academician of China Academy of Engineering.
in p>1997, the technical route of super hybrid rice breeding was put forward.
In p>2, the first stage of super rice breeding in China was achieved.
In p>24, the second phase of super rice was achieved one year ahead of schedule. He has won many domestic awards such as the National Special Invention Award and the First Highest Science and Technology Award, and 11 international awards such as the United Nations Science Award, Wolf Award and World Food Award.
Yuan Longping solved three problems in the research of three-line hybrid rice.
First, he put forward the technical scheme of "distant hybridization between wild rice and cultivated rice", and finally found an effective way to cultivate male sterile lines. In 1973, he realized the "three-line" matching of sterile lines, maintainer lines and restorer lines.
Second, a number of combinations such as "Nanyou No.2", a hybrid rice with strong heterosis, were bred and widely used in production, becoming the first scientist in the world to successfully utilize the heterosis of rice.
Third, it broke through the seed production barrier. According to previous studies, the outcrossing rate of rice was only 2.4%, and the seed yield of hybrid generation was extremely low, which was far from the production requirements. The International Rice Research Institute started its research in 1971 and gave it up in 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 production gradually increased, and now the high yield has reached more than 3 kilograms per mu.
