采用离体叶培养法测定了日本白粉病（Erysiphe graminis f. sp. tritici）的6个代表性小种对258个小麦和小黑麦品种或品系的致病性。几乎所有在日本培育和/或培养的品种和品系都对所有种族敏感，但与札幌原小麦有关的种族除外。小麦中针对日本品种的抗性基因似乎是Pms。对所有测试的霉菌品种具有抗性的几个品种和品系可能为日本和其他地方的抗性提供重要的基因来源。
The pathogenicity of six representative races of powdery mildew (Erysiphe graminis f. sp. tritici) from Japan to 258 cultivars or lines of wheat and triticale were tested using a detached leaf culture method. Almost all cultivars and lines bred and/or cultured in Japan, were susceptible to all races, with the exception of those related to Sapporoharukomugi. The resistance genes in wheat against races from Japan seem to be Pms. Several cultivars and lines with resistance to all tested mildew races may provide important gene sources of resistance in Japan and elsewhere.
