Abstrakt: The wheat line C.I. 7090 (Triticum aestivumL.) was shown by previous work to carry an unidentified gene(s) for resistance to many races of common [Tilletia caries(DC.) Tul. and T. foetida(Wallr) Liro], and dwarf bunt (T. controversaKuhn). C.I. 7090 was crossed with completely susceptible cultivars (‘Triumph’ and ‘Elgin’) and with bunt‐host differentials. The F3and F4progenies of these crosses were analyzed to determine the identity and number of genes involved in resistance. The results showed that a new gene, designated Bt9was involved and the Bt9plus Bt7conferred resistance in C.I. 7090 to 36 of the 41 reported races of common bunt. Inheritance for Bt9is independent of that for Bt1, 2, 4, 6, and 7.
