摘要
为筛选出新的抗丝黑穗病玉米种质资源,以100份新引进美国玉米自交系为试验材料,采用人工接种的方法于2013-2015年进行丝黑穗病抗性鉴定与评价。结果表明:在100份供试材料中,针对丝黑穗病表现抗病的种质共有67份,其中29份种质表现高抗(HR),12份种质表现抗病(R),26份种质表现中抗(MR),为增加种质资源遗传多样性以及丝黑穗病抗病育种提供了材料基础。
In order to select new germplasm resources with resistance to Sporisorium reilianum,using the method of manual inoculation,resistance to Sporisorium reilianum of 100 inbred linesi ntroduced from USA were identified.The results showed that 67 inbred lines were resistant.There were 29 inbred lines with high resistance,12 inbred lines with resistance and 26 inbred lines with middle resistance.The results laid materials foundation for resistant breeding to head smut and the genetic diversity of germaplasm resource.
