The reactions of five varieties of oats in the seedling and adult plant stages to seven physiologic races of crown rust, Puccinia coronata Corda var. Avenae Erikss. & Henn. were determined.All five varieties were completely susceptible in the seedling stage to all the races. Two varieties, Erban and Ajax, were resistant in the adult plant stage to some of the races and susceptible or moderately susceptible to others. Two other varieties, R.L. No. 1370 and R.L. No. 1510 were resistant in the adult plant stage to all the races used in this test, and apparently possess a generalized type of adult plant resistance to crown rust.
