摘　　要：通过对单株种植条件下苜蓿产量与株高、枝条数和枝条直径等性状间的遗传相关分析与通径分析,结果表明,在穴播条件下,株高是构成苜蓿单株产量的重要因素,与单株产量密切相关。枝条数与枝条直径对产量的直接作用相对不大。By the genetic correlation analysis and the path analysis of the traits of alfalfa that including plant height, branches and the diameter of branch about single alfalfa plant, the result showed that the plant height is the most important factor that affected the yield and correlative with the yield of the single plant. The branches and the diameter of branch didn＇t affect the yield.
