对30个紫花苜蓿材料及其农艺性状、品质性状进行对应分析。结果表明,影响产草量因子的主要性状是叶片数、侧枝长,其次是侧枝重、节间数;影响品质性状的主要因子是粗纤维、粗蛋白质,其次是钙含量。30个紫花苜蓿材料根据因子得分进行系统聚类,可划分为5个不同遗传差异的类群。 30 alfalfa materials and their agronomic traits, quality traits corresponding analysis. The results showed that the main traits affecting the yield factors were leaf number, collateral length, followed by the number of lateral branches and internodes. The main factors affecting the quality traits were crude fiber and crude protein, followed by calcium content. Thirty alfalfa cultivars were clustered according to factor scores and divided into five groups with different genetic differences.
