摘　　要：小麦高温抗条锈性是在较高温度下所诱导的一种低反应型抗病性。苗期接种条锈菌 ( Pucciniastriif ormis West.)后 ,分别采用高温 ( 2 1± 1 )℃和常温 ( 1 4± 1 )℃处理 ,测定小偃系列小麦品种的高温抗条锈性。结果表明 ,小偃系列品种中具有较多的高温抗条锈性资源。另外 ,以高温抗锈品种小偃 6号为试材 ,以高感品种铭贤 1 69为对照 ,分别接种不同条锈菌生理小种和类型 ,证实小麦高温抗条锈性不具有小种专化性。The high temperature resistance of wheat to the stripe rust is a kind of low reaction type of resistance induced by relatively higher temperature. The high temperature resistance of wheat cultivars Xiaoyan series to wheat stripe rust was investigated on wheat seedlings inoculated with Puccinia striiformis West. by high temperature treatment (21±1)℃ and normal temperature treatment (14±1)℃, respectively. The result shows that there are rich resources of high temperature resistance among Xiaoyan series wheat cultivar. In addition, inoculations of the high-temperature resistant cultivar Xiaoyan 6 with various races and types of P. striiformis confirm that the high temperature resistance of wheat to stripe rust is not of race specificity.
