Abstract
Six isolates of Tilletia caries and T. foetida, the causal agents of wheat common bunt have been collected from six regions in Iraq and identified by their reaction to 10 differential wheat lines, each containing single bunt resistant gene. Diversity of the pathogen isolates was confirmed according to their reactions. BU6 from Al-Qayarah (Mosul) was the most virulent isolate which overcome all the resistant genes except Bt7and Bt10. The least virulent isolates were BU1 and BU4. Bt7 ، Bt10 genes stayed resistant to all the isolates and the infection didn’t exceed 10%, although the isolates were mixture of Tilletia tritici and Tilletia laevis, followed by Bt5 which was resistant to most of the isolates except for BU5 and BU6 which excelled this resistance.
