Abstract
The pathogenic variation among monoconidial isolates of Pyricularia oryzae from single lesions and monospore cultures was examined with two differential cultivar sets. Tests in Korea and the Philippines indicated some variants but fewer than reported previously. Data support the hypothesis that P. oryzae is relatively stable pathogenetically and that quantitative resistance to rice blast is not due to extreme pathogenic instability in the fungus.This publication has 0 references indexed in Scilit:
