从科技部获悉,我国已在水稻、油菜、大豆、小麦四大主要农作物的研究方面取得国际领先地位。水稻是我国第一大粮食作物,其中杂交稻种植面积占55%左右。杂交稻平均比常规稻增产15-20%。我国无论是在两系法还是在三系法的水稻杂交育种研究方面都居国际领先水平。我国油菜种植面积约1亿亩,其中杂种油菜占30%。我国杂交油菜的研究和应用均处于国际领先地位。目前审定通过的油菜杂交种已有37个,其中双低的黄籽油菜品质
It is learned from the Ministry of Science and Technology that our country has achieved the international leading position in the research on the four major crops of rice, rape, soybean and wheat. Rice is China’s largest food crops, of which hybrid rice acreage accounted for about 55%. Hybrid rice average yield 15-20% more than conventional rice. Our country both occupies the leading position in the research of two-line method or three-line method in rice hybrid breeding. China’s rapeseed area of about 1 million mu, of which hybrid rape accounted for 30%. The research and application of hybrid rapeseed in China are all in the leading position in the world. At present, there are 37 rapeseed hybrids approved, of which the quality of double low yellow rapeseed
