1975, Yuan Longping conquered the "seed production barrier" and explored and summarized the success of seed production technology. 165438+1In June, the growth of hybrid rice was observed in Yuan Longping and Libihu. With the strong support of the party and the state, 19 provinces, municipalities and autonomous regions have successively formed scientific research cooperation groups to carry out large-scale scientific experiments and successfully bred hybrid rice.
1976, hybrid rice was successfully popularized. 65438-0977 Yuan Longping published two important papers: Practice and Theory of Hybrid Rice Cultivation and Key Techniques of Hybrid Rice Seed Production. 1980 10 Yuan Longping, the first hybrid rice breeder in China and a researcher at Hunan Academy of Agricultural Sciences, overcame the difficulties in seed production with the cooperation of relevant scientific research units after more than 10 years of hard research and experiments, which made the hybrid rice research a complete success and opened up a new way to increase rice production.
Long Yuan's personal evaluation
Yuan Longping devoted himself to the research of hybrid rice, invented the "three-line method" indica hybrid rice, successfully developed the "two-line method" hybrid rice, and established the technical system of super hybrid rice, making the research of hybrid rice in China always at the world leading level. By the end of 20 17, hybrid rice had spread over 9 billion mu nationwide, and * * * increased rice production by over 600 billion kilograms. He went to India, Vietnam and other countries many times to teach hybrid rice technology to help overcome food shortage and hunger.
Yuan Longping devoted all his life to the research, application and popularization of hybrid rice technology, invented the "three-line method" indica hybrid rice, successfully studied the "two-line method" hybrid rice, and established a super hybrid rice technology system, which made outstanding contributions to China's food security, agricultural science development and world food supply.
