Induced Mutation Technique and the Application on Soybean Breeding

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.
