Yuan Longping, known as the “father of hybrid rice”, is one of China’s most famous scientists. Yet, he considers himself a farmer because he continually works the land in his research. Indeed, his slim but strong body is just like that of millions of Chinese farmers, to whom he has devoted his life.

Yuan Longping was born in 1930 in Beijing. His parents wanted him to pursue a career in science or medicine. However, what concerned him most was that farmers often had poor harvests and sometimes even had a serious shortage of food to eat. To tackle this crisis, he chose to study agriculture and received an education at Southwest Agricultural College in Chongqing.

After graduating in 1953, he worked as a researcher. Yuan Longping realised that larger fields were not the solution. Instead, farmers needed to boost yields in the fields they had. How this could be done was a challenging question at the time. Yuan was convinced that the answer could be found in the creation of hybrid rice. A hybrid is a cross between two or more varieties of a species. One characteristic of hybrids is that
they usually attain a higher yield than conventional crops.

However, whether it was possible to develop a hybrid of self-pollinating plants such as rice was a matter of great debate. The common assumption then was that it could not be done. Through intense effort, Yuan overcame enormous technical difficulties to develop the first hybrid rice that could be used for farming in 1974. This hybrid enabled farmers to expand their output greatly.

Today, it is estimated that about 60 percent of domestic rice consumption in China is comprised of crops generated from Yuan’s hybrid strains, and his strains have allowed China’s farmers to produce around 200 million tons of rice per year. Yuan’s innovation has helped feed not just China, but many other countries that depend on rice as well, such as India and Vietnam. Because of his invaluable contributions, Yuan Longping has received numerous awards both in China and abroad.

Given that Yuan’s hybrids have made him quite wealthy, one might think he would retire to a life of leisure. However, this is far from the case. Deep down, Yuan is still very much a farmer at heart. As a man of the soil, he cares little for celebrity or money. Instead, he makes large donations to support agricultural research.

What impresses people most about Yuan Longping is his ongoing ability to fulfill his dreams. Long ago, he envisioned rice plants as tall as sorghum, with each ear of rice as big as a broom, and each grain of rice as huge as a peanut. He succeeded in producing a kind of rice that could feed more people at home and abroad. His latest vision for “seawater rice” has also become a reality, and potentially opened up nearly one million square kilometres of salty land in China for rice production. Despite his advanced years, Yuan Longping is still young at heart and full of vision, and everyone is waiting to see what he will dream up next.
