Twenty‐nine pathogenic races of Tilletia foetida and eight of T. caries were identified during a survey of bunt races in Turkey in 1960–1971; 244 bunted heads and eight differential wheat varieties were used in these experiments. The pathogenicity of the 21 most extensive races was checked in 1970–1971. Some of them were stable in their pathogenicity, and some were not. In further race studies carried out since 1974, using more bunt material, 11 differential wheat varieties and the new classification method, 35 T. foetida and eight T. caries races were identified. Obviously, the number of races will increase as the studies continue. The 21 most extensive races identified in the primary studies were tested on 16 wheat varieties cultivated in Turkey. All races used were virulent on nine varieties and avirulent on two varieties. Virulence on the other five varieties was variable.
