诱变育种技术在大豆育种中的应用

Induced Mutation Technique and the Application on Soybean Breeding

诱变育种作为一种有效的创造新种质的方法,已被广泛地应用于植物育种中,其诱变的方法也不断发展。目前诱变育种中常用的几种方法:电离辐射诱变、离子束注入诱变、激光诱变、微波诱变、磁诱变育种、化学诱变以及近年发展起来的航空诱变育种;对其诱变机理、在大豆育种中的应用、存在的问题以及今后的发展方向进行阐述。

As an available method of creating new germplasm, mutation breeding has been used in plan breeding comprehensively,and the methods of mutation breeding also developed continually. This paper mainly introduced several methods which always be used in mutation breeding： radiation mutation, ion-implantation mutation, laser radiation mutation, microwave mutation, magnetic mutation, chemical mutation and space mutation developed recently; besides, their mutation mechanisms ,the application on soybean breeding ,the current problems and the development trend were also discussed.
