【Abstract】 Resistance of 42 rice cultivars, imported from the United States,to the bacterial leaf blight (BLB,Xanthomonas oryzae pv.oryzae) and bacterial leaf streaks(BLS,X.oryzae pv.oryzicola) were evaluated. The results showed that 28.6%-85.7 % of tested cultivars were resistant or moderately resistant to the pathotype Ⅳ and Ⅴ of BLB,and 57.2%-83.4% were resistant or moderately resistant to the strains BS39 and BS93 of BLS.IR36M4 and Gulfrose were resistant to two different diseases.Those cultivars with high resistance to BLB were also more resistant to BLS.The possible relationship between two resistance in rice cultivars were discussed.更多还原
