Abstract: The research herein aimed to screen strains of Monascus with high pigment production,to research the relationship between the capability of pigment production and genetic diversity of Monascus,so as to lay a foundation of further study on the application of Monascus. Methods: 41 Monascus strains were solid fermented,and the clustering analysis of strains with high pigment production was carried out through ISSR( Inter-simple sequence repeat) analysis. Results: The pigment productions of M. purpureus,M. aurantiacus and M. ruber strains were higher than those of M. pilosus, M. fumeus and M. albidulus strains. Moreover, the pigment productions and productivities of M. purpureus strains on each color component were higher than those of M. aurantiacus and M. ruber strains. M. pilosus had the lowest pigment productivity among these 6 species of Monascus. It was also shown that the pigment productivities of different strains in the same species were significantly different. Conclusion: According to the results from cluster analysis,the genetic relationship of Monascus strains had a certain correlation with their geographic sources. However,the results of intra-species clustering analysis suggested that the Monascus strains with high pigment production were not clustering at all.
