Because it was Yuan Longping that developed the two-line hybrid rice, in the 1970s, through the successful research of hybrid rice in China, the yield per mu of rice was finally increased from 300 kg to 800 kg, with more than 230 million mu popularized and more than 20 billion kg increased. All these deeds are attributed to Yuan Longping.

With the trial planting of hybrid rice in various countries in the world, hybrid rice has attracted worldwide attention. In recent years, Yuan Longping has been invited to give lectures, impart technology, attend academic conferences or conduct technical cooperation research in 8 countries including the Philippines, the United States, Japan, France, Britain, Italy, Egypt and Australia 19 times. Yuan Longping's hybrid rice achievements won the first special invention award since the founding of New China in 198 1, and from 1985 to 1988, it won three international science awards in just four years.

Dr. Swaminathan, director of the International Rice Research Institute and former Indian Minister of Agriculture, spoke highly: "We call Mr. Yuan Longping the' father of hybrid rice' because his achievements are not only the pride of China, but also the pride of the world, and his achievements have brought good news to mankind." Solved the world food problem.

Extended data

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.
