对１２属１０３（亚）种２９９份小麦野生近缘植物的鉴定表明，小麦近缘植物中蕴藏着丰富的抗小麦白粉病材料，所鉴材料中１８５份为免疫或近免疫，占６２％，抗病６４份，占２１％，感病５０份，占１７％；部分种的不同材料间抗病性有差异；Ｄ组染色体的存在降低了山羊草属中一些种的抗病性；黑麦属由于染色体组中同时含有多个抗白粉病基因，对小麦白粉病菌保持稳定的免疫反应：偃麦草属、旱麦草属、大麦属、赖草属、新麦草属、鹅观草属、薄冰草属中有大量呈免疫反应的材料，是今后小麦远缘杂交抗病育种的重要基础。
The identification of 299 wild relatives of wheat in 12 genera and 103 (subspecies) showed that the wheat relatives contained abundant wheat powdery mildew resistant materials, of which 185 were immunized or nearly immunized, accounting for 62% Disease resistance 64, accounting for 21%, susceptible 50, accounting for 17%; some species of different materials have different disease resistance; D group chromosomes reduce the resistance of some species of Aegilopsia; rye Due to the genome of the genome contains multiple resistance to powdery mildew, wheat powdery mildew bacteria stable immune response: Agropyron, Prattacterium, barley, Leymus, Polaris, Roegneria, thin ice Grass is a large number of immune response material, is the future wheat distant hybridization disease breeding an important foundation.
