Abstract
The presence of soilborne wheat mosaic virus (SBWMV) in durum wheats (T. durum) in Central Italy is reported. The most widely grown durum cultivars in Italy are resistant to SBWM, but many of the new, higher-yielding, semidwarf types were found extremely susceptible. Yield losses as high as 70% have been estimated in the more susceptible cultivars. Grain number per square meter (51%) rather than kernel weight (8%) reductions accounted for most of the yield reduction. SBWM also affected test weight, plant height and weediness. Visual disease assessments made very early in the season were highly correlated with losses, but some cultivars appeared to possess efficient "tolerance" mechanisms.
