摘要
[目的]从黄淮麦区小麦资源中筛选高温抗锈性品种。[方法]对产自黄淮麦区的165份小麦品种进行苗期高温抗条锈性鉴定,并对苗期呈现抗性的品种进行大田抗性鉴定。[结果]筛选出13个苗期高温抗条锈性品种,明确了各自高温诱导的表达阶段。对这13个品种接种混合条锈菌生理小种进行大田抗性鉴定,结果表明被测品种全部抗病,且抗病性呈现非小种专化性。[结论]我国黄淮麦区的小麦品种中存在着丰富的高温抗条锈种质资源,合理利用这些资源将有助于培育持久抗条锈性品种。
[Objective] The study aimed to screen wheat cultivars with high temperature resistance to stripe rust from the wheat resources in Huanghuai growth area.[Method] Seedlings of 165 wheat cultivars from Huanghuai growth area were identified by wheat stripe rust under high temperature;then the wheat cultivars presenting stripe rust resistance at seedling stage were further used to identify the resistance in field.[Results] 13 cultivars were proved to be stripe rust resistant under high temperature,and the expression stages of stripe rust in the 13 cultivars.The field identification results were confirmed the identified results at seedling stage via mixed stripe rust of physiological races.The stripe resistances of wheat cultivars were also proved non-race-specific.[Conclusion] Wheat resources in Huanghuai growth area are abundant in wheat cultivars with high temperature resistance to stripe rust.
