摘　　要：为明确玉米新品种对穗腐病的抗性,采用双牙签接种法,对2016~2019年参加山西省品种比较试验的818个玉米杂交种进行了穗腐病抗性鉴定。结果表明:参试品种的穗腐病抗性整体水平较高,中抗及以上品种数占鉴定品种总数的91.56%。高抗品种占比在年际间变化幅度较大。高抗材料中,特早熟品种所占比例最高,达到了24.24%;中抗材料中,不同熟期类型品种所占比例差异较小,为42%左右。To identify the resistance of maize hybrids to ear rot,the resistance of 818 maize hybrids to ear rot was identified from 2016 to 2019 in Shanxi Province through the method of double toothpick inoculation.The results showed that the resistance of maize hybrids tested was high in the overall level.The hybrids with medium or above resistance accounted for 91.56%of the total.The inter-annual change of hybrids with high resistance was great.Among the hybrids with high resistance,the percentage of early maturing hybrids reached 24.42%.Among the hybrids with medium resistance,the percentage of hybrids of different maturity types was low,which was about 42%.
