Yuan Longping, who was born in September, 1930, graduated from Agriculture Department in Southwest Agricultural Institute. He has been working on agriculture education & the research into hybrid rice since he left the institute. In the 1960s, when China was suffering from serious famine, he came up with the idea of hybrid rice, which has a high yield ( or output). Ten years later, he succeeded in inventing a new species that produced a 20 percent higher yield than common types of rice. Yuan devoted himself to the research into agriculture, & was honored by UNESCO & FAO(联合国教科文组织). Although he is 74 years old, he is still working on the research into agriculture.
