TOLERANCE OF OATS TO THE SEPTORIA DISEASE

Forty-eight strains of oats (Avena spp.) from the United States Department of Agriculture World Oat Collection were assessed for septoria tolerance at Charlottetown and Ottawa and 10 of these were selected for further tests. Two years’ additional data showed that strains selected for good tolerance to the septoria disease and for high seed yield were consistent for these traits. However, their reactions to other diseases were variable. Strain C.I.8175 displayed the highest level of tolerance, the lowest disease ranking, and the highest seed yield.
