Yuan Longping 1953 graduated from Southwest Agricultural College (now Southwest University).

/kloc-at the age of 0/9, Yuan Longping was admitted to the Agronomy Department of Xianghui College in Chongqing, Sichuan, and was transferred to the Agronomy Department of Southwest Agricultural College. Southwest Agricultural College 1979 was approved by the state as a national key university. 1985, Southwest Agricultural College was changed to Southwest Agricultural University. After decades of development, Southwest Agricultural University and Southwest Normal University merged into the present Southwest University.

Now, Southwest University has established Yuan Longping Scholarship to encourage students to go deep into the foundation, take root in farmland, study hard and cultivate talents for agricultural scientific research in China.

Yuan Longping's main contributions:

1, Yuan Longping took 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 are a challenge to the classical genetic theory, denying the traditional view that "self-pollinated crops have no heterosis" and greatly enriching 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 such as "Nanyou No.2", a hybrid rice with strong advantages, were 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.
