'Down-to-earth'

Yuan believed deeply in the power of science as a harvest multiplier.

Using research and trials at his national center, he continued until close to his final days to produce increasingly higher-yielding super-hybrid plants, with panicles so full of grain that they bent, giving the appearance of a "waterfall of rice", Quinn added.

Reflecting on Yuan's achievements, which were helped by closely observing and improving plants in rice paddies, just as farmers did, Quinn said the scientist maintained a "down-to-earth" attitude.

"He always seemed more at home in a field than an office, and was most comfortable in his working clothes, just as Norman Borlaug was," Quinn said.

Yuan was also a teacher, always ready to answer questions and to speak with young scientists and students, according to Quinn.

"The American high school student we sent to his research center each year always returned filled with knowledge and a deep desire to learn more," he said.

Quinn, also vice-chairman of the International Rice Development Forum, which Yuan created, said Yuan had been an inspirational figure, just like Borlaug.

Addressing a four-day US-China Agriculture Roundtable sponsored by the US Heartland China Association on March 23, Quinn referred to Yuan's accomplishments to inspire participants.

In his statement, Quinn said, "Professor Yuan Longping, who was truly beloved in his country and by all of us who knew him, will be greatly missed.

"His legacy will provide inspiration to generations far into the future, in China and across the world."
