We are all in the position of the farmer.I we plant a good seed,we reap a good harvest.If our seed is poor and full of weeds,we reap a useless crop.If we plant nothing at all,we harvest nothing at all.
Born in a poor farmer's family in 1930 and as a graduate of the Southwest Agriculture college in 1953, Yuan Longping 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 (不恰当的)policies caused China to suffer a severe famine(饥荒)that led to many deaths.Since then, he has been devoting 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(要素)of this particular type.
In 1973, in cooperation with others, he was finally able to establish a complete process of creating and reproducing highyielding hybrid rice species.The next year they successfully cultivated(种植)a type of hybrid rice species which had great advantages.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 called the “Father of Hybrid Rice”.
In 1979, his technique for hybrid rice was introduced into the United States, the first case of intellectual property rights transfer in the history of the People's Republic of China.
However, the debates among scientists about whether quality or quantity should take priority(优先权)are frequently heard.In the underdeveloped world, the increasing output is no doubt the primary concern, while people in developed countries prefer highquality rice.
Yuan was asked to change his major concern from increasing output to improving quality and taste—a task easier to accomplish for him.But Yuan was unswayed (未受影响的).He firmly believed, in developing countries, the increasing output outweighs the urgency for a better taste,and that his foremost task was to increase the grain reserve in developing countries, instead of the quality problem of his super hybrid rice.“First we must have enough food, then comes eating well,” he said.
