摘　　要：供试的小麦条锈菌每一个中国生理小种都可以侵染多个非小麦属植物的种和属,并表现出与在小麦上相类似的寄生专化性。同一生理小种的寄生性,因供试植物的属,种或种内材料的不同而有差异。小麦条锈菌生理小种在小麦品种水平上的寄生范围,与在非小麦属植物属种水平上的寄生范围有关。The studies indicated that all the physiological races under study caused infection to many non-Triticum genera showing similar parasitic specificity to that of those on wheat varieties. The parasitism of a certain race differed with genera, species, or materials under test. And there was an indication that the parasitic range of races of P. striiformis f.sp. tritici on wheat corresponded to their parasitic ranges on the non-Triticum genera.
