turned wild rice varieties were inoculated with mixed strains of Hebei dominant physiologic races of Pyricularia oryzae and 4 Japanica differential strains(Ken54-04,Ken54-20,Hoku 1,ken53-33),Which had stable pathogenicity at seedling stage and initial stage of panicle sprouting. The result showed that 58.14 % of the 43 varieties were positive correlation between leaf and panicle blast resistance; 9 indica varieties and 1 japonica variety highly resisted rice blast; 5 indica varieties and 1 japonica vari...
