Disease readings on clones of Basin wildrye and their progenies indicated that one locus conditioned resistance to a Bozeman isolate of the stripe rust fungus, Puccinia striiformis. Frequencies of infection-type classes fit a model based on five genotypes expected in segregation from an autotetraploid. There was an apparent dosage effect for resistance.
