Barley-infecting isolates of WDV were collected in the field of near Sofia. The complete genomes of two isolates were amplified by PCR, cloned into pGEM-T plasmid and sequenced. The two clones were the same size and showed complete homology. The WDV-Bg17 clone was compared with Barley dwarf virus, Oat dwarf virus and Wheat dwarf virus isolates. Based on DNA sequences WDV-Bg17 isolate shows high homology (95–97%) to Barley dwarf virus isolates and differs from Oat dwarf virus (71% homology) and Wheat dwarf virus (85% homology).
