1975 The successful development of hybrid rice planting technology laid the foundation for the large-scale popularization of hybrid rice in China. Yuan Longping's research on hybrid rice was groundbreaking in China, China, but the first successful hybrid rice in the world was completed by American Henry Hank Beecher in 1963.
In IRRI, Philippine International Rice Research Institute 1966, Yuan Longping's hybrid rice research is pioneering in China, but it is not the first in the world. Japan's Xincheng Changyou got a set of three-line japonica rice at 1965, but it was not used for production.
1980- 198 1 year, Yuan Longping went to the United States as the technical director of the International Rice Research Institute. 1982 served as the deputy head of the national hybrid rice expert advisory group.
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.
199 1 was hired as the chief international consultant of FAO.
1995 was elected as an academician of China Academy of Engineering. 1995 two-line hybrid rice was successfully developed.
1997 put forward the technical route of super hybrid rice breeding.
In 2000, the goal of the first stage of super rice breeding in China was achieved, and in 2004, the goal of the second stage of super rice breeding was achieved one year ahead of schedule.
197 1 onwards, researcher of Hunan Academy of Agricultural Sciences, vice chairman of Hunan CPPCC, member of CPPCC Standing Committee, director of National Hybrid Rice Engineering and Technology Research Center. Published 6 monographs and more than 60 papers in Chinese and English.
2. Profile of people
Yuan Longping, 1930, was born in Beijing on September 7th. He is from De 'an County, Jiangxi Province, and now lives in Changsha City, Hunan Province. China hybrid rice breeding expert is known as the "father of hybrid rice" in China and an academician of China Academy of Engineering.
In April 2006, he was elected as a foreign academician of the National Academy of Sciences. 20 10 was awarded the honorary doctorate of Macau University of Science and Technology. In 20 1 1 year, he won the Mahathir Science Award.
He is currently a member of the 12th Chinese People's Political Consultative Conference Standing Committee, vice chairman of Hunan Provincial Political Consultative Conference and vice chairman of Hunan Science and Technology Association. Director of National Hybrid Rice Engineering Technology Research Center and Hunan Hybrid Rice Research Center, Honorary Dean of Southwest University School of Agriculture and Biotechnology, Professor of Hunan Agricultural University, Visiting Professor of China Agricultural University, Honorary Dean of Huaihua Vocational and Technical College, Honorary Dean of Hunan Biomechanics Vocational and Technical College, Chief Consultant of FAO, Honorary President of World Chinese Healthy Diet Association.
20 14 13, Yuan Longping team responded to the research on transgenic rice, which has not been put into practice. Norwegian parliamentarians nominated China's famous hybrid rice breeding experts, Indian geneticists and Pakistani human rights activists to compete for the 20 14 Nobel Peace Prize.

After reading it, the following is more interesting-
The story of Yuan Longping is 300 words.
1964, Yuan Longping began to study hybrid rice. 1966, IRRI Philippine International Rice Research Institute bred miracle rice (IR8). Nanyou 2, the first strong hybrid rice combination bred from 1974, successfully developed hybrid rice seed production technology on 1975, 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; Judging from the utilization level of heterosis, it can be divided into three strategic development stages: the utilization of heterosis among varieties, the utilization of heterosis among subspecies and the utilization of distant heterosis, that is, the utilization of heterosis is developing in an increasingly strong direction. Extended data; Yuan Longping's contribution is 1, and Yuan Lao's greatest contribution is to construct a perfect theoretical system of hybrid rice. He devoted himself to the research of hybrid rice all his life, and successfully developed three-line hybrid rice, two-line hybrid rice and super hybrid rice, which greatly increased the yield per unit area of rice. As a star scientist, he also serves as an ambassador for agricultural product promotion. Nowadays, people pay more and more attention to food safety. Super rice and transgenic technology all need professionals like Yuan Lao to reassure the public. In addition, Yuan Lao also trained a large number of talents from all echelons in the field of hybrid rice. It has solved the problem of shortage of talents, technology and funds in China's agricultural field. It provides a strong guarantee for the development of agriculture in China. He also spread this technology to the world, making China's agriculture on the world stage. Reference source; Baidu Encyclopedia-Yuan Longping

The story of Yuan Longping is about 300 words.
1964, Yuan Longping began to study hybrid rice. 1966, IRRI Philippine International Rice Research Institute bred miracle rice (IR8). Nanyou No.2, the first strong hybrid rice combination, was bred by 1974, and the seed production technology of 1975 was successfully developed, which laid the foundation for the 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; Judging from the utilization level of heterosis, it can be divided into three strategic development stages: the utilization of heterosis among varieties, the utilization of heterosis among subspecies and the utilization of distant heterosis, that is, the utilization of heterosis is developing in an increasingly strong direction. Extended data:
Yuan Longping's contribution is 1, and Yuan Longping has taken 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 challenged the classical genetic theory and denied the traditional view that "self-pollinated crops have no heterosis", which greatly enriched the theory and technology of crop genetics and breeding. 2. 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 with strong heterosis, such as "Nanyou No.2", have been 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. 3. 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.
