摘 要 ：对来自我国不同地区的玉米杂交种穗粒腐病原分离鉴定的结果表明，镰刀菌（Ｆｕｓａｒｉｕｍ）和蠕孢菌（Ｈｅｌｍｉｎｔｈｏｓｐｏｒｉｕｍ）是引起杂交种穗粒腐的优势菌群，分离频率较高的病原菌还有本霉菌（Ｔｒｉｃｈｏｄｅｒｍａ）、青霉菌（Ｐｅｎｉｃｉｌｌｉｕｍ）、曲霉菌（Ａｓｐｅｒｇｉｌｌｕｓ）等。种子产地来源地原菌的分离频率有很大影响，辽宁和山西玉米杂交种穗粒腐病原菌的优势种群是蠕孢菌，而山东和河南则以镰刀

Abstract:The pathogens of ear and seed rot in maize hybrid collected from different areas of China were isolated and identified. The results show that Fusarium spp. and Helminthosporium sp. are the main pathogens. Trichoderma sp. , Penicillium spp. and Aspergillus
