袁隆平的贡献英文

Yuan LongpingBorn in Peking, Yuan Longping graduated from Southwest Agricultural College in China in 1953, and then was assigned to teach crop genetics and breeding at an agricultural school in Hunan Province. He began his research in hybrid rice development in 1964 and subsequently was transferred to the Hunan Academy of Agricultural Sciences in 1971 to serve as a research professor. It was there, two years later, that he achieved a major scientific breakthrough as he successfully developed the genetic materials essential for breeding high-yielding hybrid rice varieties.Professor Yuan is widely acknowledged for the discovery of the genetic basis of heterosis in rice—a phenomenon in which the progeny of two distinctly different parents grow faster, yield more, and resist stress better than either parent. In developing his “three-line system” of hybrid rice, Professor Yuan and his team soon produced a commercial hybrid rice variety called Nan-you No. 2, which was released in 1974. With yields 20 percent higher than previous varieties, Professor Yuan’s new crop immediately began to improve food availability in China.  翻译：袁隆平出生于北京,1953年毕业于西南农业大学在中国,然后被分配到教作物遗传和育种在湖南省的一所农业学校。他在1964年开始研究杂交水稻发展,随后被转移到湖南农业科学院1971年作为研究教授。两年后,在那里他取得了重大的科学突破,成功地开发出遗传材料必不可少的繁殖高产杂交水稻品种。元教授被公认为杂种优势的遗传基础的发现米饭现象中两个截然不同的子代的父母长得更快,产生更多,抵抗压力比的父母。在发展他的杂交水稻“三体系”,元教授和他的团队很快产生一个商业杂交水稻品种叫Nan-you 2号,于1974年被释放。比之前的品种产量高20%,元教授的新作物立即开始改善中国的食品供应。
