我国首创的转基因水稻已走出实验室 ,完成大田试验示范。据中国水稻研究所基因工程组黄大年研究员介绍 ,在杂交稻种中混入假杂种或杂草 ,对稻米质量和种植效益影响很大 ,目前我国杂交水稻种植面积占水稻播种面积的一半以上。要使这一作物生产跨上新的台阶 ,必须培育优质高产良 Our country’s first genetically modified rice has come out of the laboratory to complete field experiments and demonstrations. According to Huang Dainian, a genetic engineering engineer at the China National Rice Research Institute, introduction of fake hybrids or weeds in hybrid rice varieties has a great influence on the quality and planting efficiency of rice. At present, the acreage of hybrid rice in China accounts for more than half of the sown area of ​​rice. To bring this crop production to a new level, it is necessary to cultivate high quality and high yield
