摘要
高温抗条锈性是在相对高温下表达的一种低反应型抗病性。首次在中国西北地区东部小麦品种资源中发现了２８个具有高温抗条锈性的冬小麦品种。其中１６个为农家品种，１２个为改良品种。这些品种分属全生育期高温抗锈、苗期高温抗锈和成株高温抗锈３种类型。讨论了高温抗条锈品种的特点和应用潜力。
High-temperature resistance to stripe rust was a resistance of low infection type at higher tempera-ture.For the first time,28 varieties with high temperature resistance to stripe rust were discovered from wheat variety resources in eastern growth area in China North west.These varieties consisted of 16 land races and 12 im proved varieties. The characteristics of high temperature resistance to stripe rust in these varieties was as follows:some varieties expressed high temperature resistance at all stages of growth,some varieties at seedling stage and the others at adult stage.The character istics of resis-tance to stripe rust and potential application of these varieties were discussed.
