A total of 1333 barley cultivars collected from various regions of the world were tested for a resistance to scald at adult and seedling stages by field and artificial infections, respectively. In the field trial, 140 cultivars or 11% were found to be highly resistant, and most of them were the occidental cultivars. Particularly, Ethiopian cultivars showed quite high frequency of resistant one. It was found that the resistance of Ethiopian cultivars was significantly related to the rachilla-hair type; quite many resistant cultivars were found to be a short-haired type. First leaves of 1085 cultivars among the above materials were artificially inoculated by a culture isolated from susceptible plant (cv. Minorimugi) grown at the same field. Only 29 cultivars collected from the occidental regions showed a highly resistant reaction. Some of them classified into susceptible type in the seedling test were resistant under the field condition. It may be suggested that these cultivars have a kind of field resistance.
