The most effective way to control sugarcane smut is to plant resistant varieties. The evaluation of resistance to sugarcane smut is a very important procedure in the breeding of resistant varieties. In order to evaluate the resistance to smut of the eight new sugarcane clones bred by Sugarcane Research Institute of Guangxi Academy of Agricultural Sciences, the suspension of mixed Sporisorium scitamineum was inoculated to the new clones to obtain the incidence, also the natural incidences of smut in the field were investigated. The investigation period included new planting and first ratoon of sugarcane. ROC22 was used as the control. The results showed that GT12-765 and GT12-2262 were resistant to smut; the clones GT12-2476 and GT12-2004 were moderately resistant; GT12-162 was moderate susceptible; GT12-762, GT12-2425 and GT12-917 were susceptible to smut; and the CK (ROC22) was susceptible. The artificial inoculation could be used to more accurately evaluate the resistance to sugarcane smut, compared to the natural infection. The results of this study would provide a basis for breeding sugarcane varieties with high resistance to smut.
