In the described experiments the interaction of 460 grass species with a mildew population obtained from Dactylis glomerata L. 'Motterwitzer' was examined. 420 species remained free of symptoms, while 40 species were susceptible. The most susceptible ones were Dactylis aschersoniana Graebner, Dactylis glomerata L., Dactylis glomerata spp. aschersoniana (Graebn.) Thell., and Dactylis polygama Horvat, but all showed differences in their behaviour. The unexpectedly low susceptibility of Dactylis woronowii Ovcz. should be examined again. Three grass species Bouteloua hirsuta Lag., Danthonia provinzialis DC., and Sesleria latifolia (Adam) Degen were also highly susceptible to cocksfoot mildew, while on wild grasses of the species Agropyron, Bromus, Festuca, Mibora, Poa, and Sesleria only few symptoms could be seen. Among cereals only barley could be infected by cocksfoot mildew. Not only in the wild form of Dactylis glomerata L. but also in the cultivated variety 'Motterwitzer', above 10% were found to be free from infection. Therefore the breeding of resistant varieties of Dactylis glomerata L. seems to be feasible.
在所述实验中，研究了460种草种与从鸭茅‘Motterwitzer’分离得到的白粉菌群体之间的相互作用。420种草种未出现症状，而40种草种易感病。最易感病的是阿氏鸭茅、鸭茅、阿氏鸭茅亚种、多花鸭茅，但它们的表现均存在差异。沃罗诺夫鸭茅出人意料的低易感性应再次进行研究。三种禾本科植物硬毛布顿草、普氏扁芒草和宽叶大颖草也对白粉菌高度易感，而在冰草属、雀麦属、羊茅属、小粟草属、早熟禾属和大颖草属的野生禾本科植物上仅能看到少数症状。在谷类作物中，只有大麦会被白粉菌感染。不仅在鸭茅的野生形态中，而且在栽培品种‘Motterwitzer’中，都发现有超过10%未受感染。因此，培育鸭茅抗病品种似乎是可行的。
