Yuan Longping is an agronomist and hybrid rice breeding expert. Jiangxi De'an people. Born on September 7, 1930.
In 1953, he graduated from the Department of Agronomy of Southwest Agricultural College. He has served as a researcher, director of the Hunan Hybrid Rice Research Center, honorary president of the Hunan Academy of Agricultural Sciences, director of the National Hybrid Rice Engineering Technology Research Center, and was elected as an academician of the Chinese Academy of Engineering in 1995.
Yuan Longping has long been engaged in the theoretical research and practice of hybrid rice breeding technology. In 1964, he first proposed the idea of cultivating a three-line method of "sterile line, maintainer line, and restorer line" to use rice heterosis and carried out scientific experiments. In 1970, together with his assistants Li Bihu and Feng Keshan, they discovered a male sterile wild rice plant with pollen abortion in Hainan, which became the key to breaking through the "three-line" matching.
In 1972, the first large-scale application of rice male sterility line "Erjiunan No. 1 A" and the corresponding maintenance line "Erjiunan No. 1 B" in China were bred, and the following year, the first large-scale promotion of the strong combination "Nanyou No. 2" was bred, and a complete set of seed production technology was developed. In 1986, the strategic idea of hybrid rice breeding was proposed, which was divided into "heterosis utilization between varieties by three-line method, heterosis utilization between subspecies by two-line method and distantly related heterosis utilization by one-line method". He is known as the "father of hybrid rice" by his peers
