[目的]鉴定现阶段河南省小麦主推品种及区试参试品系的抗病性,从中寻找出多抗品系,以利于小麦生产应用.[方法]120种小麦品种自然种植,不进行人工接种,在病圃内病害发病高峰期,根据记载标准分别调查各品种对纹枯病,白粉病和叶锈病3类病害的抗病性.[结果]全部120份材料中,无1份材料对纹枯病、白粉病和叶锈病同时表现为免疫或高抗,无1份材料对2种病害同时表现为免疫,有6份材料对3种病害表现为2种高抗1种中抗,占供试材料的5%,有6份材料对3种病害同时表现为中抗,占供试材料的5%.[结论]所鉴定的小麦品种抗白粉病和叶锈病的效果较好,对纹枯病的抗性则相对较差.

[Objective] To identify and evaluate the resistance of mainly popularized wheat cultivars and regional lines to wheat diseases, and find some multi-resistant cultivars (lines) which could be used in wheat production in Henan Province in the future. [Method] A total of 120 wheat cultivars were planted under natural condition without artificial inoculation. During morbidity peak period, the resistance investigations of all the wheat cultivars to the three wheat diseases including wheat sharp eyespot, powdery mildew and leaf rust according to record standards. [Result] The results showed that no cultivar (line) showed high or immunity resistance to the three diseases, and no cultivar (line) showed immunity resistance to two diseases. As many as six cultivars (lines) showed two high and one middle resistance, which accounted for 5% of all tested materials. As many as six cultivars (lines) showed middle resistance to the three diseases, which also accounted for 5%. [Conclusion] All the tested materials showed better resistance to wheat powdery mildew and leaf rust, but poor resistance to wheat sharp eyespot.
