A collection of 53 samples representing both diploid and tetraploid species of Avena was tested under various conditions for reaction to three cultures of crown rust and two of stem rust. Resistance to all three crown rust races occurred only in two samples of the tetraploid A. strigosa ssp. barbata and only one of these was also resistant to the stem rust cultures.
