Yuan Longping (1September 7, 930-) was born in Beijing. My ancestral home is De 'an, Jiujiang, Jiangxi, and now I live in Changsha, Hunan. China hybrid rice breeding expert, academician of China Academy of Engineering. He is currently the director of China National Hybrid Rice Work Technology Center and Hunan Hybrid Rice Research Center, a professor at Hunan Agricultural University, a visiting professor at China Agricultural University, the chief consultant of FAO, the vice chairman of Hunan Association for Science and Technology, and the vice chairman of Hunan CPPCC.

In April 2006, he was elected as a foreign academician of the American Academy of Sciences. According to his hybrid rice varieties and research, the unit yield of rice has increased from 300 kg per mu to more than 900 kg. He is also widely known as the "father of hybrid rice".

1980 in may, Yuan Longping went to the United States for technical guidance on hybrid rice seed production at the invitation of the United States. In September, China Academy of Agricultural Sciences and International Rice Research Institute jointly held an international training course on hybrid rice technology in Hunan Academy of Agricultural Sciences. As the keynote speaker, Yuan Longping taught experts from more than 65,438+00 countries the main courses on hybrid rice.

In September of the following year, the second issue was held continuously. From June to 10, 5438, he went to the Philippine International Rice Research Institute for technical guidance and cooperative research. In 2003, Yuan Longping directed doctoral students to carry out research on introducing genomic DNA of distant species into rice, and transgenic a batch of foreign DNA into rice.

Before adulthood, Yuan Longping followed his family from Beiping to Tianjin, from Jiangxi to Hubei, and from Chongqing to Nanjing. He was lively and naughty when he was young. Seeing grandma's hookah steaming, I took a sip curiously and choked to death.

Grandma ran into him and hit him hard on the head. Among his brothers and sisters, he is the most playful. When he was studying in Chongqing, he ran to the Jialing River to swim as soon as the air raid alarm sounded. It happened to be seen by my father through a telescope, and it was another good battle to go home.

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 getting simpler and simpler and the efficiency is getting 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.

Yuan Longping solved some key technical problems in the dual-system method. For example, 1989, when the research of two-line method encountered great setbacks, he put forward the initial temperature index and technical strategy for breeding practical photo-thermo-sensitive genic male sterile lines, which made the research of two-line hybrid rice out of the trough.

Later, the core seed production program and cold water series irrigation propagation were put forward, which made the research of two-line hybrid rice finally successful and popularized. Since 1987, he has served as a special responsibility expert for the "863" project and presided over the national collaborative research. 1995 two-line hybrid rice was successfully studied, and the yield of two-line hybrid rice was 5% ~ 10% higher than that of three-line hybrid rice at the same maturity stage.
