There were close relation and harmonies among the quantities characters that were significantly hereditarily correlated with tumorous stem yield. High yield breeding combining with strong ecological adaptability and good quality should be largely based on later maturity, tumorous stem diameter, whole plant weight and higher ratio of stem and leaf.

瘤茎产量与营养生长期、瘤茎膨大期、瘤茎横径、茎/叶、株鲜重呈极显著遗传正相关，与菜形指数、菜皮百分率呈极显著遗传负相关，与其余性状相关均未达显著水平；与瘤茎产量显著相关的性状间关系密切，有很好的协同性，分析提出茎瘤芥育种选择熟性晚、瘤茎横径大、茎/叶高和植株个体较大的品种，可实现品种产量高、生态适应性强和瘤茎品质较佳等三者的协调统一。

Tumorous stem yield was only significantly hereditarily positively correlated with vegetative duration, developmental duration, ratio of stem and leaf, horizontal length and whole plant fresh weight, negatively fur percentage and tumorous stem index.
