Abstract

A cross was made between two isolates, Guy 11 and 6-28, of Magnaporthe grisea that are pathogenic to rice. Progenies were tested for avirulence/virulence on eight rice cultivars. Both parents and all progeny were virulent on rice cultivar S201. Isolates Guy 11 and 6-28 differed in virulence on seven cultivars. Segregation among the progenies for avirulence/virulence on the seven cutlivars indicated that at least seven genes were segregating.
