| 摘 要： | 在P群玉米种质沈137抗病鉴定结果的基础上,系统评价了沈137高抗弯孢叶斑病、灰斑病,兼抗大斑病、小斑病、南方锈病、穗腐病、茎腐病、丝黑穗病和矮花叶病等9种病害的抗病性及其抗病基因丰富而稳定的遗传特性。沈137是国内骨干自交系中抗病种类最多的自交系之一。充分利用沈137这类多抗资源及深入挖掘其应用潜力将成为应对玉米病害突发所带来生产隐患的重要途径。

| Abstract: | Based on systemic identification of disease resistance of Shen137,one inbred line of the P group of maize germplasm,it was found that Shen137 is a good multiple resistance inbred line,with high resistance to Curvularia leaf blight and gray leaf spot,moderate resistance to Turcicum leaf blight,Maydis leaf blight,southern corn rust,ear rot,stalk rot,head smut,and dwarf mosaic virus,suggesting that the use of Shen137 is important to prevent the outbreak of disease problems in maize production. |
