Blumeria graminis f.sp. tritici (syn. Erysiphe graminis f.sp. tritici) causes an important disease of wheat (powdery mildew) to which Hordeum vulgare and H. chilense are resistant. The study of chromosomal addition lines of H. vulgare and H. chilense in wheat showed that they possessed resistance to wheat powdery mildew. This was expressed as a reduction of disease severity but it was not associated with increased macroscopically visible necrosis. The resistance is of broad genetic basis, conferred by gene(s) present on different chromosomes of both H. vulgare and H. chilense. The feasibility of transferring this resistance to wheat is discussed.
小麦白粉病菌（同义词：禾本科布氏白粉菌小麦专化型）引发小麦的一种重要病害（白粉病），而大麦和智利大麦对该病害具有抗性。对小麦中大麦和智利大麦染色体附加系的研究表明，它们对白粉病具有抗性。这种抗性表现为病害严重程度降低，但与肉眼可见的坏死增加无关。该抗性具有广泛的遗传基础，由大麦和智利大麦不同染色体上存在的基因赋予。文中讨论了将这种抗性转移到小麦中的可行性。
