摘　　要：为明确我国各地区玉米品种对玉米南方锈病的抗性水平,为品种推广和抗病品种科学布局提供依据,利用85个玉米品种对海南三亚、广东河源、广西河池和湖南邵东4个地区的玉米南方锈菌菌株进行了田间抗病性比较试验。结果表明,相同品种对不同地区来源菌株的抗性水平有差异。综合各地区玉米南方锈菌的抗性评价可知,玉研505、鲁宁184、蠡玉88、太平洋99和绿海200等9个品种对玉米南方锈病的抗性最强,优迪598、三北63、联创839和冠玉911等19个品种次之,禾新9号、德禹M8、宁玉502、新玉27和晨强808等17个品种抗病性最弱。供试品种中,表现为高抗、中抗和感病的品种百分比分别为10.59%、22.35%和67.06%,说明我国玉米品种整体上表现为对玉米南方锈病抗性较差,病害容易流行,需注意预防。The resistance of corn varieties to southern corn rust in different regions of China was studied. This study evaluated the resistance of 85 corn varieties to Puccinia polysora from Sanya of Hainan, Heyuan of Guangdong, Hechi of Guangxi and Shaodong of Hunan. The results showed that the same variety had different resistance to southern corn rust from different regions. The comprehensive evaluation of resistance showed that nine varieties, including Yuyan 505, Luning 184, Liyu 88, Taipingyang 99 and Lühai 200 had high resistance to southern corn rust;19 varieties, including Youdi 598, Sanbei 63, Lianchuang 839 and Guanyu 911, had moderate resistance to southern corn rust;17 varieties, including Hexin 9, Deyu M8, Ningyu 502, Xinyu 27 and Chenqiang 808 were high susceptibility. The ratio of corn varieties with high resistance, middle resistance and susceptibility to southern corn rust were 10.59%, 22.35%, and 67.06%, respectively. The resistance of corn varieties in China to southern corn rust was insufficient. It is likely to occur the epidemic of diseases, and precautions should be taken against it.
