Abstract
Eighty-three third backcross lines which comprise a set of near isogenic lines (NIL's) of the barley cultivar 'Clipper' but each carrying a different chromosomal segment from Hordeum spontaneum, marked with a distinct isozyme, were tested for resistance to three races of the barley leaf rust pathogen (Puccinia hordei). Fourteen lines showed resistance to at least one race and three showed resistance to all three races. The resistance in two of these lines was controlled by separate, single partially dominant genes. In one case the resistance gene named Rph10 was on chromosome 3 and linked (r = 0.15 .+-. 0.05) with the isozyme locus Est2. In the second case, the gene (Rph11) was on barley chromosome 6 and linked (r = 0.07 .+-. 0.02) with the isozyme locus Acp3 and (r = 0.11 .+-. 0.02) with Dip2.
