Abstract: Plant mutagenesis technology is using external factors to accelerate species variation and acquire some valuable mutants in the short period. This technology has been an important tool for new materials breeding, variety cultivation and gene function research. Compared with the natural selection, plant mutagenesis technology has more advantages, such as a higher mutant frequency, larger mutation range and shorter mutation period. This paper mainly introduces the mutational mechanism and biological effects of chemical, physics, space, biology mutagenesis, and their research progress of applications in plant in detail. Also some disadvantages of these technologies are mentioned and good suggestions for future development are proposed.

Key words: chemical mutagenesis, physics mutagenesis, space mutagenesis, biology mutagenesis, research progress
