Název v původním jazyce

Wheat streak mosaic virus: incidence in field crops, potential reservoir within grass species and uptake in winter wheat cultivars

Popis výsledku v původním jazyce

Wheat streak mosaic virus (WSMV) has become a re-emerging pathogen in cereal crops in the Czech Republic. The incidence of the virus was recorded in recent years in several winter wheat fields and many grass species. Although the range of infected samples was low (6.4% of the total tested samples), a high incidence of well-distributed virus was recorded. In at least six fields, the virus reached severe and potentially epidemic levels. We found that some grass species acted as experimental hosts and possible reservoirs of the virus; these included Anthoxanthum odoratum (sweet vernal grass), Arrhenatherum elatius (false oat-grass), Lolium multiflorum (Italian rye-grass), Bromus japonicus (Japanese chess), Echinochloa crus-galli (barnyard grass), Holcus lanatus (meadow soft grass) and Holcus mollis (creeping soft grass). Some of these grass species are also important weeds of cereals, which may be the potential source of WSMV infection in cereal crops. Several widely used winter wheat cultivars were tested in the field after artificial inoculation with WSMV to evaluate virus titre by RT-qPCR. The low virus titre was recorded in cultivars Caldwell, Cubus, Florida, Matchball and Cim rana, which is associated with mild disease symptoms and may provide a good level of crop resistance to WSMV.
