Nine rice cultivars were evaluated for blast resistance relatively to the partially resistant check IR36and the susceptible check B40,based on the measurement of resistant spectrum,lesion size,lesion density and diseased leaf area.Results indicated that three cultivars,namely Sanhuangzhan 2,Sanluzhan 7 and Meisanwu 2 appeared high qualitative and quantitative resistance either under artificial inoculation with 220 isolates of Guangdong Province or under a wide range of environmental diverse population of Pyricularia grisea, which may be considered to contribute the highly and stable blast resistance in different latitude in rice growing zone in China.But in some cases,the level of qualitative and quantitative blast resistance is not always positively correlated in the same cultivar.
