PURPOSE: A microsatellite marker for distinguishing lineage of red mold pathogen and a method for distinguishing lineage of red mold pathogen using the same are provided to quickly and accurately distinguish lineage of a main contamination source of complex red mold pathogen from a grain sample by analyzing PCR using FgmsAAG93. CONSTITUTION: A primer, FgmsAAG93, of sequence numbers 1 and 2 is used for specifically amplifying a microsatellite of red mold to distinguish lineage of a main contamination source among red mold pathogens. A method for distinguishing lineage of F. graminearum comprises: a step of amplifying a gene using FgmsAAG93; and a step of identifying a microsatellite site of the amplified gene. A kit for distinguishing and diagnosing lineage of the red mold pathogens contains the primer and a reagent for amplification.
