| Abstract: | From November 2018 to March 2019, a total of 302 suspected virus-infected cucumber leaf samples were collected from 8 regions (Sanya, Ledong, Dongfang, Danzhou, Chengmai, Haikou, Wanning and Wuzhishan) in Hainan Island. Five viruses were detected including Cucumber mosaic virus (CMV), Melon yellow spot virus (MYSV), Cucumber green mottle mosaic virus (CGMMV), Tobacco mosaic virus (TMV) , and Cucurbit chlorotic yellows virus (CCYV) by small RNA deep sequencing and RT-PCR. The detection rate was 32.79%, 31.46%, 23.18%, 9.61% and 2.65%, respectively. Detection rate of co-infection was 11.28%. There were 8 kinds of co-infection types, and the co-infection of two viruses occurred most often. The distribution and species of viruses from cucumber in Hainan were clarified. |
