摘　　要：本研究根据5个苜蓿品种单株鲜重、株高、分枝数、枝条直径和茎叶比5个性状的田间观测结果，进行株高、分枝数、枝条直径、茎叶比与单株鲜重的灰色关联度分析。尽管各苜蓿品种的5个性状存在显著差异，但各品种株高、分枝数、枝条直径、茎叶比与单株鲜重的灰色关联度则大致相似。其中以枝条直径最大，株高次之，分枝数与茎叶比又次之。该结果对高产苜蓿新品种的选育提供了有价值的参考。Based on field observed results of plant weight, plant height, branching number, branch diameter, stem and leave rate, grey relation degrees of plant height, branch numbers, stem diameter, stem and leave rate to a plant fresh weight were analyzed in the paper. Even though five characters of five alfalfa varieties were significant difference, grey relation degrees of plant height, branches number, branches diameter, stem and leave rate to a plant fresh weight were similar. Among the grey relationdegree, branch diameter was the first, plant height was second, branching number and stem and leave rate were similar. The result is of value to supply reference for breeding of high yield alfalfa new varieties.
