摘要
以２２个茎芥菜（茎瘤芥）品种（系）为试材，对６个性状与单株产量的关系进行通径分析。结果表明：瘤茎横径是影响单株产量最重要的性状。各性状对单株产量作用大小顺序是瘤茎横径＞单株质量＞叶长＞叶宽＞单根质量＞瘤茎纵径。其丰产性育种应在增大瘤茎横径的基础上，选择植株个体大、叶较长、较宽的品种。
The relationship between yield per plant and 6 different characters was analyzed by use of 22 tumorous stem mustard varieties. The results showed that the tumorous stem diameter was the most important characters to affect the yield per plant. The effects of 6 characters on yield were arranged from large to small in order of the action of character on yield:tumorous stem diameter,whole plant fresh weight,length of the largest leaf,width of the largest leaf,root fresh weight and tumorous stem length. High yield breeding should be largely based on tumorous stem diameter,whold plant weight,longer and wider leaves.
