Discussion on and application of mutagenesis techniques in super-high-yielding wheat breeding

In this paper, we particularly described the concept of super-high-yielding wheat, the theoretical basis of its breeding and the significance of its development. Meanwhile, we analyzed the current situation of super-high-yielding wheat breeding and put forward the problems existed in super-high-yielding wheat breeding, and clarified the importance of artificial mutation in wheat germplasm enhancement. Furthermore, according to years of mutation breeding practice, we briefly introduced some research results in super-high-yielding wheat breeding and germplasm enhancement. (authors)
