Born into a poor farmer's family in 1931 and a graate from the Southwest Agriculture Institute in 1953, Yuan began his teaching career at an agriculture school in Anjiang, Hunan Province.
He came up with an idea for hybridizing rice in the 1960s, when a series of natural disasters and inappropriate policies had plunged China into an unprecedented famine that caused many deaths.
Since then, he has devoted himself to the research and development of a better rice breed.
In 1964, he happened to find a natural hybrid rice plant that had obvious advantages over others. Greatly encouraged, he began to study the elements of this particular type.
In 1973, in cooperation with others, he was able to cultivate a type of hybrid rice species which had great advantages. It yielded 20 percent more per unit than that of common ones.
The next year their research made a breakthrough in seeding. They successfully developed a set of technologies for procing indica (long-grained non-glutinous) rice, putting China in the lead worldwide in rice proction. For this achievement, he was bbed the "Father of Hybrid Rice."
In 1979, their technique for hybrid rice was introced into the United States, the first case of intellectual property rights transfer in the history of new China.
At present, as much as 50 percent of China's total rice fields grow Yuan Longping’s hybrid rice species, yield 60 percent of the rice proction in China. Due to Yuan's hard work, China's total rice output rose from 5.69 billion tons in 1950 to 19.47 billion tons last year, about 300 billion kilograms more have been proced over the last twenty years. The annual yield is enough to feed 60 million people.
The "Super Rice" Yuan is now working on yields are 30 percent higher than those of common rice. A record yield of 17,055 kilograms per hectare was registered in Yongsheng County in Yunnan Province in 1999.
