| Abstract: | In this study,the causal agents were identified from Canna indica viral diseased plants in Yunnan Province.The diseased C.indica plants mainly exhibited the symptoms like veinal chlorosis and yellowing,streak mosaic or interveinal chlorosis,while older leaves always showed veinal necrosis as well as chlorosis.Viral pathogens were detected by RT-PCR/PCR in 24 diseased C.indica samples collected from Kunming and Yuxi City in Yunnan Province.The results indicated that the main C.indica-infecting viruses were canna yellow mottle virus (CaYMV),bean yellow mosaic virus (BYMV),sugarcane mosaic virus (SCMV).CaYMV showed the highest detection rate of 87.5 %,whereas,the BYMV had the lowest rate of 16.7% in the 24 samples.Co-infections of CaYMV+SCMV,CaYMV+BYMV and CaYMV+SCMV+BYMV were also detected in the diseased samples.However,cucumber mosaic virus (CMV),tobamovirus,luteovirus,orthotospovirus,begomovirus and umbravirus were not detected in these samples.This is the first report of CaYMV and SCMV infecting C.indica in Yunnan province. |
