Abstract
The inheritance of resistance to an Ottawa isolate of H. sativum was studied in two varieties of barley, Anoidium and Br. 3962-4, resistant to the root rot and seedling blight phase of the disease. Anoidium and Br. 3962-4 each possess two dominant genes for resistance. The genes in Anoidium are allelic or closely linked with those of Br. 3962-4. No linkage was detected between the gene for awn character in linkage group 7 and the genes for resistance.
