Evaluation of 226 barleys from Ethiopia for disease reaction to pathogens prevalent in Canada indicated that this region is a good source of resistance to Pyrenophora teres and Septoria passerinii but not to Cochliobolus sativus, Puccinia graminis tritici or barley stripe mosaic virus. Barleys with resistance to Ustilago nuda were confined to a relatively small area within the region.
