“突变育种”。利用物理、化学等诱变因素使生物体发生突变的一种育种方法mutation breeding

• 运用空间技术进行微生物诱变育种是培育新生物菌种的有效方法

  applying spatial techniques to perform microorganism mutation breeding is an effective method to breed new varieties of bacteria

• 该所早已建设了物理实验平台，用离子束来诱变育种。

  This institute set up a physics experiment platform long ago, and uses ion beams to perform mutation breeding.
