1994 - 2002年小麦品种(系)抗条锈性鉴定与监测

1994—2002年经对3822份小麦品种(系)材料抗条锈性鉴定结果表明，冬小麦抗条锈性优于春小麦，甘肃品种抗条锈性优于国内其它省区品种。田间抗条锈性监测结果表明，我国主要生产品种均表现感病，甘肃主要生产品种仅陇鉴127等少数几个品种抗病，抗源材料中也仅有中四等少数品种表现抗病，结合抗病性鉴定、监测结果及田间综合农艺性状观察，筛选出20余份可供育种利用的抗源材料。同时在针对今后抗条中31、32号等主要小种类型的抗病育种、抗病性监测等方面进行了讨论。

Identification of Wheat Varieties (lines) for Resistance to Stripe Rust in 1994- 2002

wheat varieties (lines) were identified for resistance to different races of Puccinia striiformis f.sp tritici, a causal agent of wheat stripe rust, in Gansu during 1994-2002. The results showed that the resistant level of winter wheat was higher than that of spring wheat and the resistance of Gansu's varieties was better than that of varieties collected from other provinces. The results in the fields indicated that the varieties released in the main wheat production areas were susceptible to stripe rust and only a few Gansu's varieties, such as Longjian 127, were resistant. Some of resistant sources used in breeding at present were resistant and some became susceptible. By artificial inoculation with different races, field monitoring for resistance to stripe rust and powdery mildew and survey of agronomic characteristics, 20 accessions were identified as good sources for breeding in the future.
