摘　　要：为精准评价冬小麦品种田间对条锈病的抗性,科学指导抗病育种和抗病材料的合理应用。在位于甘肃陇南不同生态区的甘肃省农业科学院植物保护研究所甘谷试验站和汪川良种场两地,于2017—2020年,对122个国家区域试验品种进行了连续3 a的成株期抗条锈病性评价。结果表明,有WJ18-1等19个品种3 a两地均表现抗病,且抗性表现稳定,占供试品种的15.57%;WJ18-494等49个品种具有慢条锈特性,占供试品种的40.16%。绝大多数品种表现出差异性,菌源、环境是主要原因。To precisely evaluate the resistance of winter wheat varieties agains stripe rust in the field and to scientifically guide disease resistance breeding and the rational application of disease resistant materials,from 2017 to 2020,122 winter wheat varieties in the national wheat variety regional trials were used to evaluate their resistance to stripe rust in field at two different locations including Gangu Experimental Station,Institute of Plant Protection,Gansu Academy of Agricultural Sciences(IPP GAAS)and Wangchuan Farm,which are hot spots of Puccinia striiformis f.sp tritici(Pst)in southern Gansu Province of China.The results showed that 19 wheat varieties including variety WJ18-1 had stable resistance in three years at both sites,which accounted for 15.57%of the tested materials.49 wheat varieties including variety WJ18-494 had slow rusting characteristic,which accounted for 40.16%of the tested materials.Most of the tested materials showed diverse performance which indicated that virulent structures of Pst and environment change were the main reasons for the differences in resistance.
