| 摘 要： | 通过系统调查和试验查明,天水地区种植的重要品种77-69和成良5号、6号已丧失抗条锈性,引致这些品种丧失抗锈性的原因主要是条中29号小种及其相近致病类型的出现和发展,山区低温为引致变异的重要诱因。提出成良5号、6号应停止种植,77-69高产可在川区控制使用,并提出了抗性比较稳定的品种。

| Abstract: | The important wheat cultivars 77-69 and Chengliang No. 5 and 6 cultivated in Tianshui area have lost their resistance to stripe rust jhrough the systematic surveys and experiments. The appearance of new virulent YC race 29 is the main cause of inducing the Breakdown of resistance to stripe rust of three cultivars, and low temperature in mountain areas also gives it important influence. Also, it is suggested that Chengliang No. 5 and 6 be stopped planting and that high-yielding cultivar 77-69 be controlled in use in the valley lands, and some wheat cultivars with stable disease resistance are recommended. |
