摘　　要：为了筛选适合在北方地区推广种植的生产性能较高的黑麦草(Lolium spp.)品种,试验通过对12个黑麦草品种(剑宝、邦德、特高、安格斯1号、寿刚、先锋、绿色精神、伯乐、双筒枪、Hercules、Ribeye、Mqximus)的生产性能(鲜草总产量、干草总产量)、鲜干比进行研究,采用对比分析、K-means聚类分析方法综合阐释单一品种属性及其归类属性,并依据差异表现对品种进行归类。结果表明:在12个供试品种中,特高的鲜草总产量、干草总产量最高,鲜干比居中,然后依次为Hercules、安格斯1号。通过聚类分析,可将12个品种分为3类,第1类包括剑宝、邦德、Mqximus、特高、安格斯1号、寿刚、Hercules 7个品种,第2类包括Ribeye、先锋、绿色精神3个品种,第3类包括伯乐、双筒枪2个品种,其中第1类的综合表现好于第2类和第3类。说明在北方地区的黑麦草生产中,可结合实际在第1类中做选择。In order to select out ryegrass(Lolium spp.) varieties with higher production performance suitable for planting in Northern regions, the production performance(total fresh grass yield and total hay yield)and fresh-to-dry ratio of 12 ryegrass varieties(Jianbao, Abundant, Tetragold, Angus 1,shouqun, Avance, Green spirit, Bolt, Double-barrd, Hercules, Ribeye and Mgimus) were examined in the experiment. Comparative analysis and K-means cluster analysis were used to comprehensively explain the attributes of a single variety and its classification attributes, and the varieties were classified according to their differences. The results showed that Tetragold had the highest total yield of fresh grass and hay, and the fresh-to-dry ratio was in the middle among the 12 varieties, followed by Hercules and Angus 1. The 12 varieties were divided into three categories by cluster analysis. The first category included seven varieties(Jianbao, Abundant, Mqximus, Tetragold, Angus 1,Shougun and Hercules), the second category included three varieties(Ribeye, Avance and Green spirit), and the third category included Bolt and Double-barrel. Among which, the comprehensive performance of the first category was better than that of the second and third categories. In the ryegrass production in the Northern region, the first category can be selected out based on the actual situation.
