一、问题的提出及意义 吃饭是中国头等重要的事情。由于人口众多,加上人民生活改善对粮食转化产品的需求,要保持一定的粮食消费水平,这是一个十分艰巨的任务。为解决这个问题,国家把两系法杂交水稻纳入“863”重点科研项目。以袁隆平为代表的农业科学家们经多年研究把水稻的光、温敏型雄性不育性和广亲和性两个遗传基因组合在一起,从而使杂交水稻种子生产技术由三系法
First, the question raised and the significance of eating is China’s first and foremost important thing. Due to the large population and the improvement of people’s living standards for food conversion products, it is a very arduous task to maintain a certain level of food consumption. To solve this problem, the state has put two-line hybrid rice into “863” key scientific research projects. Agricultural scientists represented by Yuan Longping, after years of research, combined the two genes of light, thermo-sensitive male sterility and broad compatibility to make hybrid rice seed production technology consist of three lines
