| Abstract: | From October 2017 to April 2019, a total of 290 suspected virus-infected watermelon leaf samples were collected in 7 urban areas (Wenchang, Wanning, Lingshui, Sanya, Ledong, Dongfang, Changjiang) in Hainan island. Nine viruses were detected including MYSV, WSMoV, CCYV, CMV, TMV, CGMMV, ZYMV, WMV and PRSV by small RNA deep sequencing and RT-PCR. The detection rates of MYSV, CCYV, CGMMV, ZYMV, CMV, WSMoV, PRSV, TMV and WMV were 66.90%, 25.86%, 22.07%, 17.59%, 10.00%, 7.59%, 5.52%, 2.76% and 1.03% respectively. The co-infection rate of virus was 56.56% and 14 types of mixed infections were detected. The results of this study clarify the identification and distribution of waterme-lon-infecting viruses in Hainan. |
