Abstract: Based on the genome comparison analysis between Fusarium oxysporum f. sp. niveum(Fon)and other closely-related pathogens, the specific sequences of Fon were obtained. Then we developed specific primers that could amplify Fon-specific DNA bands. Combined the Fon-specific primers with the universal primer of Fusarium oxysporum (W106R/W106S), we established a duplex PCR method that might rapidly and accurately detect Fon by 1 PCR reaction, which is beneficial to technically support the rapid identification of Fon by method of molecular detection..

Key words: Fusarium oxysporum f. sp. niveum, duplex PCR, Fusarium oxysporum
