摘要：

对播种当年18个苜蓿品种材料根系形态特征进行了研究，结果表明：不同类型苜蓿根系形态指标差异明显；利用根系形态特征的10个指标对18个实验材料进行聚类，可分为4类；建议在苜蓿选种时，选取根颈直径大，入土深度深、主根长度长、侧根直径大、侧根发达的材料。

Abstract:

The root morphological characteristics of 18 alfalfa varieties were researched, the results showed that: root morphological indexes were significantly different among alfalfa varieties. Using the 10 morphological indexes of root system, 18 varieties could be clustered into 4 groups through clustering analysis. It is suggested alfalfa varieties selection could be based on larger crown diameter and lateral root diameter, deeper crown depth, long taproot length, developed lateral root.
