[Abstract]
Radiation mutagenesis breeding is one of the modern breeding techniques that accelerate the natural variation of organisms by physical methods, so as to quickly obtain new germplasm with excellent characters and form new varieties with stable characters through strict breeding. It does not involve the introduction of foreign genes and can greatly shorten the breeding cycle. The basic principles, characteristics, biological effects of six major radiation mutagenesis breeding methods, including 60Co-γ radiation, heavy ion radiation, atmospheric and room temperature plasma, ultraviolet erythema effect, laser radiation and space mutagenesis, and their applications in the breeding of Chinese medicinal materials were reviewed. The safety and application prospect of relevant radiation mutagenesis technology in the field of Chinese medicinal materials were discussed, which provided reference for the relevant research and application of radiation mutagenesis breeding for Chinese medicinal materials.
