We determined DNA fingerprints and pathotypes on international differentials for 151 isolates of the rice blast fungus Pyricularia grisea that were collected from 15 rice cultivars at a blast disease breeding nursery in Santa Rosa, Colombia. The pathogen population expressed an extraordinarily hi...

Forty-five international races of Pyricularia grisea, representing all nine race groups, were identified in a "hot spot" breeding site (Santa Rosa) in Colombia, with the largest number included in the IA group. The international race system did not fully describe the virulence spectrum of the iso...
