First Report of Soil‐Borne Wheat Mosaic Virus ( SBWMV )‐Infecting Triticale in Poland

The virus in naturally infected, stunted triticale plants was identified as soil‐borne wheat mosaic virus ( SBWMV ). The infected plants were collected in the S outhern W ielkopolska region ( W estern P oland). Molecular analysis including RT ‐ PCR , and sequencing of the complete coding sequence of coat protein gene, was performed. The sequence of the P olish isolate of SBWMV ( SBWMV ‐Pol1) shared 100, 99 and 98% identities with the corresponding regions of D e1 ( AF 519799), OKL ‐1 ( X 81639) and US ‐ N ebraska ( L 07938) isolates of SBWMV , respectively. Phylogenetic analyses showed that the P olish isolate, SBWMV ‐ P ol1, clustered together with other SBWMV isolates. This is the first report of the occurrence of SBWMV in P oland and the second of its presence in E urope.
