PIONEER FOR AII PEOPLE
Yuan Longping,known as the "father of hybrid rice",was one of China's most famous scientists.Yet,he considered himself a farmer because he continually worked the land in his research.Indeed,his sim butstrong body was just like that of millionsof Chinese farmers, to whom he had 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 serioos tage of food to eat.To tackle this crisis, he chose to study agriculture anoreosiedLaneducation at Southwest Agricultural College inChongqing.
After graduating in 1953,he worked as aresearcher.Yuan Longping realised that larger fields were not the solution. Instead,farmers needed to boost yields in the fields they had.How this couldbe done was a challenging question at the time.Yuanwas 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
