Abstract: In recent years,the use of space environment mutagenesis,ion beam irradiation and nuclear radiation mutagenesis has become increasingly active in improving crop and exploring new genes in China. Induced mutagenesis technology used in sesame new material creation and new cultivar breeding began in 1950. According to incomplete statistics of the FAO/IAEA database,up to March 2017,there are officially released 3 246 mutant cultivars from 217 crop species in more than 60 countries of the world;25 sesame mutants were released by 8 countries,China released 5 sesame mutants,ranking in the second while accounting for 20% of the total. In this paper,the results of mutagenesis of sesame and the mutations of agronomic traits and disease resistance of sesame are reviewed,and the objectives and methods of future sesame mutation breeding are also discussed. This paper aims at providing an important theoretical reference for the study of sesame functional genomics to provide rich and diverse materials and sesame germplasm innovation.
