通过对贵阳花溪地区小麦白粉病菌的毒力调查,表明各品种毒力频率有相当大的差异:“百泉565”为85％,“高加索”为80％、“白免3号”为47.5％、“肯贵阿”为32.5％、“CI12633”为22.5％、“小白冬“为15％、“Khapli”为5％。以5％为界限,确定其抗白粉性有无利用价值,“百泉565”系统、”高加索”系统、”白免3号的系统丧失了利用价值,其它抗源系统可利用一段时间。“Khapli”品种的发病情况特殊,幼苗期及成株抽穗前抗病,抽穗后颖壳和芒上发病,但抗性仍较好。
Through the virulence survey of wheat powdery mildew in Huaxi area of Guiyang, the virulence frequency of each species showed quite different: “Baizen 565” was 85%, “Caucasus” was 80%, “Baizhong 3” was 47.5% 32.5% for Kennedy A, 22.5% for CI12633, 15% for Beverly Hills and 5% for Khapli. To 5% as a limit to determine the use of anti-white powder with or without value, “Baiquan 565” system, “Caucasus” system, “Bai free 3 system lost value, other anti-source system can be used for some time.” Khapli "had special disease incidence, disease resistance before seedling stage and adult plant heading, and glume and mantle incidence after heading, but the resistance was still good.
