Yuan Longping (1September 7, 930 -202 1 May 22, 2000), male, Han nationality, Beijinger, non-partisan in Dean County, Jiujiang City, Jiangxi Province. Famous agricultural scientist at home and abroad, pioneer and leader of hybrid rice in China, close friend of China, outstanding representative of personages without party affiliation, winner of "Medal of the Republic", former vice chairman of Hunan Provincial Political Consultative Conference, former director of National Hybrid Rice Engineering Technology Research Center, and academician of China Academy of Engineering, he is known as the "father of hybrid rice"? .

Yuan Longping devoted himself to the research, application and popularization of hybrid rice technology, invented "three-line method" indica hybrid rice, successfully developed "two-line method" hybrid rice, and established the technical system of super hybrid rice. The "Three Crops and Four High Yields Project" was put forward and implemented, and 6 monographs and more than 60 papers were published in Chinese and English by using the technical achievements of super hybrid rice.

Main contribution

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 research on sexual cooperation in China. 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.
