[摘要]
以外引的20个美国玉米群体为试验材料，对其主要性状及玉米丝黑穗病抗性进行评价。连续两年接种鉴定表明，多数群体表现抗病，其中群体BSLCSC7表现为高抗，BS10CFRC10、BS12CH1C8和BS26等6个群体表现为抗病，BSCAD-1、BSCAD-2和BSCAD-3等7个群体表现为中抗，其余6个群体表现感病或高感。农艺性状鉴定表明，大部分供试群体在黑龙江省具有较好的适应性，其中群体BSCAD-3和BS12CH1C8的产量、产量构成因子及对玉米丝黑穗病抗性等性状表现较好，在育种中可优先利用。

[Abstract]
The agronomic traits and resistant responses of 20 maize populations were investigated.The evaluations for two consecutive years showed that BSLCSC7 was rated as highly resistant,6 populations such as BS10CFRC10,BS12CH1C8,BS26 as resistant,and 7 populations such as BSCAD-1,BSCAD-2,BSCAD-3 as moderately resistant,and the others as susceptible or highly susceptible.Most populations tested had good adaptability in Heilongjiang province,and BSCAD-3 and BS12CH1C8 have good performance in grain yield and yield components and head smut resistance which could be used in breeding program.
