| Abstract: | A total of 54 samples of Brassicaceae crops showing symptoms of mosaic, mottling, vein banding and/or leaf deformation were collected in Kyiv region (northern central part of Ukraine) in 2014–2015. A half of collected samples was found to be infected with Turnip mosaic virus (TuMV), and TuMV was detected in samples from Brassica oleracea var. capitata (cabbage), Raphanus sativus, Brassica juncea, Raphanus sp., Sinapis alba, Camelina sativa and Bunias orientalis (weed). The full‐length sequence of the genomic RNA of a Ukrainian isolate (UKR9), which was isolated from cabbage, was determined. Recombination analysis of UKR9 isolate showed that this isolate was an interlineage recombinant of world‐Brassica and Asian‐Brassica/Raphanus phylogenetic groups. This study shows for the first time the occurrence of TuMV in Ukraine. |
