Abstract:

Powdery mildew, stripe rust, leaf rust are harmful diseases to reducing yield in wheat. In order to select the source resistance, we have measured 308 germplasm resources by the method of field investigation. The result of this study showed that 19 of them with high resistance to powdery mildew, 68 of them with high resistance to stripe rust, 50 of them with high resistance to leaf rust resistant and 3 of them with high resistance to all these three diseases. And these results are references for wheat breeding.
