摘要

To understand virus infection situation of integrated demonstration and regional test sugarcane varieties in national sugarcane system in Guilin City,Guangxi Province,leaf samples with or without symptoms were collected from 37 sugarcane varieties,and five kinds of viruses were detected by RT-PCR with specific primers,including Sugarcane yellow leaf virus(SCYLV),Sugarcane streak mosaic virus(SCSMV),Sorghum mosaic virus(SrMV),Sugarcane mosaic virus(SCMV)and Sugarcane bacilliform virus(SCBV).The results showed that SCYLV was detected from four sugarcane varieties,and the detection rate was 10.81%;SCSMV was detected from five sugarcane varieties,and the detection rate was 13.51%;SrMV was detected from four sugarcane varieties,and the detection rate was 10.81%;SCMV had not been found;SCBV was detected from 27 sugarcane varieties,and the detection rate was 72.9%.Additionally,mixed infection of different viruses was widespread,and the total mixed infection rate was 21.62%.Thus,integrated demonstration and regional test sugarcane varieties in national sugarcane system in Guilin City had been seriously infected by viruses,and mixed infection of different viruses was common.The paper will provide a reference for breeding and popularization of antiviral sugarcane varieties.
