美国的两个科研小组最近公布了同一项科研成果。他们培植了一种能把所需要的新遗传基因传给下一代的玉米.科学家们把这一重大进步誉为农业科技的一大突破。研究人员说:此项技术使科学家们可以按育种目标培育出抗病、抗虫和抗除莠剂能力及其它抗性的玉米新品种。而且比目前所使用的杂交育种技术更为有效。 The two scientific research groups in the United States recently announced the same scientific research. They fostered a corn that can pass the new genetic genes it needs to the next generation, and scientists have cited this major advance as a breakthrough in agricultural technology. The researchers said: This technology enables scientists to breed breeding targets for disease resistance, insect resistance and herbicide tolerance and other resistant new varieties of corn. It is more effective than the current hybrid breeding technique.
