Abstract
5 sugarcane parents and 5 sugarcane varieties were selected to identify the response to smut disease by means of dipping inoculation and 4 of them by puncturing inoculation.The results show that ROC25 has high level of resistance to smut,Guitang29 and Guitang02-963 are medium resistant while Guitang02-1156,Guitang33,Guitang21 and Guitang02-649 are susceptible;Yuetang93-159,Guitang11 and ROC22 were highly susceptible by dipping inoculation.Guitang21,ROC25,Yuetang93-159 and Guitang11 are all highly susceptible by means of puncturing inoculation.The results provided the basis for commercialization of new varieties and for selection of parental breeding lines,and the varied role of different inoculation methods in the evaluation of resistance to smut.
