Rice blast caused by Pyricularia grisea was the most important disease in the rice production and seriously influenced the yield and quality.This paper reviewed the application of molecular markers to the analysis of genetic population of structure in blast pathogen and stated the quality of genetic lineages. At the same time the relationship between pathotype and genetic lineages of blast pathogens was analized and the relative factors resulting in the changes of blast pathogen population structure were studied.
