摘　　要：The genetic diversity of 110 strains of Ustilaginoidea virens from Liaoning province and Beijing where the types of rice variety constitution were different,was assessed by AFLP.The results showed that the coefficient of strains from Liaoning and Beijing was 0.92 and 0.55 respectively,and the strains from Beijing were divided into two distinct groups.There was no specific DNA pattern for the isolates from the same rice varieties,and there was no correlation between the clusters based on genetic similarity coefficient and variety origin of isolates.The genetic diversity of 110 strains of Ustilaginoidea virens from Liaoning province and Beijing where the types of rice variety constitution were different, was assessed by AFLP.
