The characterization of population structure ofblast pathogen contributes to the rational de-velopment and the deployment of blast-resis-tant cultivars. To study the population struc-ture of blast pathogen in northern China,DNA fingerprinting of 192 blast isolates col-lected in 8 representative districts in 1996 wasconducted by using Pot 2-PCR method.
