SUMMARY The reaction of forty‐one wheat varieties to the three Cambridge physiologic races of Ustilago tritici has been determined by a combination of the embryo test and growth in the field. Wide variations in susceptibility were observed and there was no consistent relationship between the extent of mycelial distribution in the scutellum and subsequent field reaction to infection. Immunity is rare. The best differential varieties for identifying the three races are suggested.
