Barley stripe mosaic infection caused moderate to severe reduction in plant height, total culms, dry-matter production, kernel weight, test weight, and grain yield in 8 spring wheat varieties. The average yield reduction attributable to infection was 32.8% in the 8 varieties. Protein percentages were higher in grain from the diseased plots than from the healthy plots. Variety C.I. 13041 was not greatly affected. The application of nitrogen tended to increase symptom development of the disease.
