我们在《新疆小麦品种与新疆小麦叶锈菌相互作用初报》(见本刊1984年第5期)中研究了新疆15个小麦品种(系)与新疆174个小麦叶锈菌菌株的相互作用.研究结果表明,新疆当前推广的冬小麦品种和大部分新品系的毒力频率值都很高(多数达86.2—100.0%,少数在50%左右),急需培育抗叶锈的新品种来代替之.本试验在上述研究的基础上,继续研究一些品种与新疆小麦叶锈菌群体的相互作用,以使为育种工作提供可作抗病新本的信息. We studied the interaction between 15 wheat cultivars (lines) in Xinjiang and 174 wheat leaf rust strains in Xinjiang in the “Preliminary Report on the Interactions between Wheat Varieties from Xinjiang and Wheat Leaf Putip Xinjiang” (No. 5, 1984) The results showed that the frequency of virulence of winter wheat cultivars and most new strains currently popularized in Xinjiang are very high (up to 86.2-100.0%, a few are about 50%), and it is urgent to cultivate new varieties resistant to leaf rust Based on the above research, this experiment will continue to study the interaction between some varieties and wheat leaf rust population in Xinjiang, so as to provide the information for the new breeding disease resistance.
