十九个小麦良种用六个叶锈菌优势小种分小种测定,其中十八个表现高度抗病,是用来自河北、北京176个叶锈菌株进行多菌株、分菌株测定时,就没有一个品种对所有菌株都抵抗,感病率为9.1—61.4%.说明研究锈病应有群体观点.比较了新疆和河北、北京叶锈菌群体的毒性.根据一些中度抗病品种对两地叶锈菌的反应,都表明新疆叶锈菌群体的毒性比河北、北京的强.在不同生态条件下形成的叶锈菌群体的毒性可能不同,因此研究锈病应有生态观点.寄主和病原物的相互作用及其遗传变异是长期的,寄主和病原物共同进化.研究锈病应有进化观点.过去的研究工作有片面性,应考虑改进.
Nineteen wheat cultivars were tested with the dominant species of six smallpox species, of which 18 were highly resistant to disease and were tested with 176 strains of leaf rust from Hebei and Beijing, A variety of resistant to all strains, the prevalence of 9.1-61.4%, indicating that the research should be a group of rust point of view.Compared Xinjiang and Hebei, Beijing leaf rust fungal population.According to some moderate resistance varieties of two leaves The results showed that the virulence of the leaf rust fungus population in Xinjiang was stronger than those in Hebei and Beijing. The toxicity of the leaf rust population formed under different ecological conditions may be different, so the ecological viewpoint of rust should be studied. Interactions and their genetic variation are long-lived, with co-evolution of hosts and pathogens. Studies of rust should have an evolutionary view. Past research has been one-sided and should be considered for improvement.
