玉米大斑病是我省玉米的主要病害之一,为了尽快找出抗源,加速玉米抗病品种的选育和利用进程,及早控制和减轻其为害,我们从1979年开始对我省主要玉米杂交种(42个)、常用自交系(113个)进行了抗玉米大斑病菌鉴定。鉴定结果表明,中单2号等16个杂交种为抗病品种,占杂交种鉴定总数的38.1%;辽1311等27个自交系为抗病材料,占自交系鉴定总数的23.8%。
Corn blight is one of the main diseases of corn in our province, in order to find out the source of resistance as soon as possible, speed up the process of breeding and utilization of resistant varieties of corn, control and mitigate their damage as early as possible, Hybrids (42), commonly used inbred lines (113) were identified against S. turcica. The results showed that 16 hybrid varieties such as Zhongdan No.2 were resistant varieties, accounting for 38.1% of the total hybrids. 27 inbred lines of Liaoning 1311 were disease-resistant materials, accounting for 23.8% of the total number of inbred lines identified.
