小麦品种与育种材料抗气传病害鉴定研究

Evaluation of resistance of wheat variety and parental material to the air-spread disease.

用山西省目前小麦气传病害(包括条锈病、叶锈病和白粉病)主要优势生理小种和致病类型的混合菌,采用人工接菌方法,对1111份小麦品种和育种材料进行抗病性鉴定,并对其中479份小麦品种和育种材料进行条锈菌分小种鉴定,累计5357种次,为育种提供抗病信息、抗源材料,并为小麦品种审定提供抗、耐病依据。

Experiments were conducted to evaluate the resistance of wheat varieties and parental materials to the air -spread disease caused by the dominant physiological races （including stripe rust, leaf rust and powdery mildew） and pathological types in Shanxi Province. 1111 samples were inoculated with the mixed race and 479 samples were inoculated with different physiological races of stripe rust by hand. This work provides more information and anti-sources for breeders and a scientific basis of the examination of wheat varieties.
