Advance of New Techniques in Wheat Mutation Breeding

Mutation induction technique has played an important role in wheat improvement.In this paper,the current status of new techniques for mutation induction and breeding in wheat was briefly reviewed.The new induction methods and their experimental advances of ion beam implantation,aerospace induction and biological factors were analyzed at different aspects of mutagenesis mechanism,induced biological effect,mutant germplasm creation and mutant variety development.The perspective of new techniques for mutation induction in wheat was also discussed.
