摘　　要：Sugarcane mosaic disease, caused by Sugarcane mosaic virus (SCMV), Sorghum mosaic virus (SrMV), Maize dwarf mosaic virus (MDMV) or Johnsongrass mosaic virus (JGMV) in Potyvirus, is one of the most important viral diseases of sugarcane. In the study, four primer pairs specific to SCMV, SrMV, MDMV and JGMV, respectively, were designed and used to detect 29 sugarcane leaf mosaic samples collected from 9 locations in Jiangxi province. The representative RT-PCR products were sequenced. The results showed that 22 samples were infected by SCMV, three by SrMV, and four were mix-infected by SCMV and SrMV. MDMV or JGMV were not identified in all samples. The result indicates that SCMV is the major pathogen of sugarcane mosaic disease in Jiangxi province, and SrMV is also a pathogen for the disease.Sugarcane mosaic disease, caused by Sugarcane mosaic virus （SCMV）, Sorghum mosaic virus （SrMV）, Maize dwarf mosaic virus （MDMV） or Johnsongrass mosaic virus （JGMV） in Potyvirus, is one of the most important viral diseases of sugarcane.
