The inheritance of resistance to powdery mildew was investigated in 20 accessions of Hordeum spontaneum and in 20 F 4 lines derived from crosses between the variety ‘Aramir’ and 13 accessions of H. spontaneum. Two resistance genes were detected in 17 accessions, and three resistance genes in one accession. In two accessions, only one resistance gene was present. The 20 breeding lines showed a large variation in infection type and infection level. The genetic relationship between the resistance genes detected was investigated in the seven most resistant F 4 lines. These F 4 lines were divided into three groups which carried different resistance genes. In two lines, the detected resistance gene was shown to be race‐specific.
