| 摘 要： | 本研究旨在利用30个不同生态区玉米品种筛选出适合雁门关地区种植的青贮玉米品种。采用随机区组试验设计，测定并分析各品种农艺性状、生物产量、营养品质，同时用聚类分析法将30个供试品种分成4个类群并分析总结每一类群的主要特性。结果表明：1）以渝青3号和曲辰9号为代表的青贮专用型玉米品种表现为生物产量和干草产量较高，穗位高较高，持绿性表现较好，但营养品质低于粮饲通用型玉米。2）以屯玉661和先玉1225为代表的粮饲通用型玉米表现为干草产量低，但淀粉含量较高，其超过30%。3）生物学产量与绿叶数、绿叶重、株高、茎粗、茎重和穗重呈显著正相关。根据田间表现和综合评价结果，曲辰9号、晋单65、先单405为适宜在雁门关地区推广种植的青贮玉米品种。

| Abstract: | The aim of this study was to select varieties of silage maize （Zea mays） suitable for cultivation in the Yanmenguan area from 30 maize varieties from different ecological zones. The 30 varieties were planted with a randomized block experiment design， and the agronomic traits， biological yield， and nutritional quality of each variety were measured and analyzed. The 30 tested varieties were divided into four groups in a cluster analysis， and the main characteristics of each group were analyzed and summarized. It was found that： 1） Two silage maize varieties， Yuqing No.3 and Quchen No.9 had higher biomass and hay yield， a high value for ear height， and better stay-green performance than that of other varieties， but these two varieties had lower nutritional quality than the grain and forage maize varieties. 2） The grain and forage maize varieties Tunyu 661 and Xianyu 1225 showed low hay yield， but high starch content （>30%）. 3） The biological yield was significantly positively correlated with the number of green leaves， green leaf weight， plant height， stem diameter， stem weight， and ear weight. Based on field performance and multi-trait evaluation results， Quchen No.9， Jindan 65， and Xiandan 405 were identified as the most suitable silage maize varieties for cultivation in the Yanmenguan area. |
