摘　　要：采用人工接种鉴定方法评价了920个玉米杂交种对丝黑穗病的抗病性。结果表明,高抗型占1.3%,抗病型占10.1%,中抗型占12.6%,感病型占62%,高感型占20.9%。在不同区试类型品种中,中抗-高抗型中晚熟和青饲玉米较多,分别占37.1%和23.3%;早熟、夏播、特早熟玉米居中,分别占18.5%、17.3%、16.7%;糯、甜玉米较少,占8.6%和5.4%。经抗病鉴定,通过审定的160个品种有4个高抗、11个抗病、19个中抗。Taking the method of artificial inoculation,the resistance of 920 maize hybrids to head smut were identified and evaluated.The result showed that 1.3% maize hybrids were highly resistant,10.1% maize hybrids were resistant,12.6% maize hybrids were moderately resistant,62% maize hybrids were susceptible and 20% maize hybrids were highly susceptible.Test of maize hybrid in different areas and types showed that 37.8% later-maturing maize hybrids and 23.3% succulence maize hybrids,18.5% early-maturing maize hybr...
