Abstract A field near Huccorgne, in the province of Liege, Belgium, sown with the winter barley cv. Express has been showing slight mosaic symptoms since 1990. As the symptoms were attributed to an infection by barley yellow mosaic bymovirus, experimental plots for evaluation of the resistance of barley breeding material were established there from 1991 onwards. Symptoms were scored by visual assessment on a range of cultivars including old French varieties, some resistant Japanese material and breeding material from the Plant Breeding Station, Gembloux. The results were compared with those obtained for the same material sown in a field infected with the common BaYMV and barley mild mosaic bymovirus isolates. The differences in the behaviour of some cultivars or lines in the 2 fields were due to the emergence of a new virus strain, which, at present, is limited to this particular field. Molecular-based detection techniques and partial sequencing showed that the new viral agent is a strain of BaYMV.
