摘要： The spore powder of Ganoderma lucidum (G. lucidum) has been proven to have a variety of pharmacological activities, and it has become a new resource for the development of health products and pharmaceuticals. However, the scarcity of natural resources, strict growth conditions and difficulty in controlling the stable yield, and quality of different culture batches seriously limit the development and utilization of G. lucidum spore powder. In the present study, the strain with the highest spore powder yield, G0109, was selected as the original strain to generate mutants of G. lucidum using ultraviolet ray irradiation. A total of 165 mutagenic strains were obtained, and fifty-five strains were chosen for the cultivation test. Importantly, one mutagenic strain with high spore powder yield and strong resistance to undesired microorganisms was acquired and named strain UV119. More cultivations demonstrated that the fruiting body and basidiospore yields from UV119 were, respectively, 8.67% and 19.27% higher than those of the parent (G0109), and the basidiospore yield was 20.56% higher than that of the current main cultivar "Longzhi No.1". In conclusion, this study suggested that ultraviolet ray irradiation is an efficient and practical method for Ganoderma strain improvement and thus provided a basis for the development and application of G. lucidum spore production and outstanding contributions to the rapid development of the G. lucidum industry.
