Abstract: In order to investigate the level of smut resistance of sugarcane parents,using mixed spores of Sporisorium scitamineum as the inoculum source,which collected in main sugarcane-producing areas in Zhanjiang,Guangdong Province,and by the means of dipping inoculation method,meantime,smut resistance identification had been carried out to 34 sugarcane parents through new plant field experiments,the results showed that the level of resistance to highly resistant(HR) of the parents had Q171,ROC1,and Neijiang 57-614,with accounting for 8.8%;Funong 95-1702,N:Co376,CP93-1382,CP65-357,Ganzhe 95-108 and ROC5 were resistant to smut(R),accounting for 17.6%;the members of Brazil618,Yuetang 89-113 and Taiyou were moderately resistant to smut(MR),accounting for 8.8%;Yuetang 86-368,ROC16,Q179,Q191,HoCP95-988,Taitang 89-1626,Yin 8 and F177 were performed moderately susceptible to smut(MS),accounting for 23.5% of the tested parents;Q205,ROC23,N:Co310,Liucheng 03-48,Q189,F134,Yuetang 83-271,Guitang 94-119,TH10 and Ganzhe 14 were susceptible to smut(S),accounting for 29.4%;Besides,Zhanjiangzhong,Yuetang 06-666,08-144 and HoTH409 were highly susceptible to smut(HS),accounting for 11.8%. In addition,it was also discussed that the grading method of sugarcane smut resistance in this study.
