Abstract

Representative isolates of Rhizoctonia solani AG1-IA associated with rice sheath blight obtained from North Vietnam were characterized using rep-PCR fingerprinting and ITS-5.8S rDNA sequencing. For rep-PCR assays primers ERIC2 and BOXA1R were used. Sequences of these isolates were aligned with other known R. solani sequences from the GenBank. Rep-PCR analysis revealed that two genotypes (Rep-Vet1 and Rep-Vet2) were present based on the fingerprinting dendrograms having the similarity coefficient score at 75% differentiation. The two clonal populations were scattered and had different geographical localizations in North Vietnam.
