Occurrence of the N ew Y ork Strain of Soil‐Borne Wheat Mosaic Virus in N orthern G ermany

Sequence analysis has shown that diseased wheat plants in N orthern G ermany were infected with the N ew Y ork strain of soil‐borne wheat mosaic virus ( SBWMV ). This is in contrast to the only other confirmed site of SBWMV occurring in G ermany, where a variant closely related to the N ebraska‐type strain of SBWMV was found. The results indicate that there have been at least two separate introductions of SBWMV strains to G ermany. A survey is required to study the actual distribution of SBWMV in G ermany.
