Biography

Yuan was born in Beijing, China in

He graduated from the Southwest Agriculture Institute in and began his teaching career at an agriculture school in Anjiang, Hunan Province.

He came up with an idea for hybridizing rice in the s, when a series of natural disasters and inappropriate policies had plunged China into an unprecedented famine that caused many deaths.

Since then, Yuan has devoted himself to the research and development of a better rice breed.

In , 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.

The biggest problem by then, was having no known method to reproduce hybrid rice in mass quantities, and that was what Yuan set out to solve. In , Yuan created his theory of using the probably-existing naturally-mutated male-sterile rice individuals for the creation of reproductive hybrid rice species, and in two years he managed to find a few individuals of such male-sterile rice that he predicted could be used for his research.

Subsequent experiments proved his theory feasible, which was his most important contribution on hybrid rice.

Yuan went on to solve more following problems. The first experimental hybrid rice species cultivated didn't show any significant advantage over common ones, so Yuan suggested to crossbreed rice with its further relative: the wild rice.

In , he found an important specie of wild rice that he needed for the creation of high-yield hybrid rice species. In , in cooperation with others, he was finally able to establish a complete process of creating and reproducing high-yield hybrid rice species.

The next year they successfully cultivate a type of hybrid rice species which had great advantages.

Hybrid rice has since been grown in dozens of countries in Africa, America, and Asia—boosting food security and providing a robust food source in areas with a high risk of famine. ISSN At present, as much as 50 percent of China's total number of rice paddies grow Yuan Longping's hybrid rice and these hybrid rice paddies yield 60 percent of the total rice production in China.

It yielded 20 percent more per unit than that of common ones, putting China in the lead worldwide in rice production. For this achievement, he was dubbed the "Father of Hybrid Rice."

At present, as many as 50 percent of China's total rice fields grow Yuan Longping’s hybrid rice species and yield 60 percent of the rice production in China.

Due to Yuan's hard work, China's total rice output rose from billion tons in to billion tons last year, about billion kilograms more have been produced over the last twenty years. The annual yield increase is enough to feed 60 million people.

The "Super Rice" Yuan is now working on has yields 30 percent higher than those of common rice.

A record yield of 17, kilograms per hectare was registered in Yongsheng County in Yunnan Province in
