In this study, strains of Xanthomonas campestris pv. translucens from North and South America were examined for differences in virulence on a set of potential differential wheat cultivars. Seedlings of 19 wheat cultivars were inoculated with 81 strains of the pathogen isolated from wheat, barley, rye, or triticale and rated for percent water-soaking in the inoculated area 8 days after inoculation. Averaged over all cultivars, 69 virulent strains caused 14.4-38.1% water-soaking, and 12 weakly virulent strains caused 1.1-4.5%. Averaged over the 69 virulent strains, five susceptible cultivars had 43.4-75.0% water-soaking, and 17 resistant cultivars had 5.5-22.8% [...]
