【摘要】 以14个茎瘤芥优良种质为试材,对9个主要性状变异及相关性进行了分析。结果表明:①瘤茎产量变异最大,营养生长期变异最小,各性状变异由大到小依次为瘤茎产量＞株鲜重＞茎/叶＞菜形指数＞横径＞叶宽＞纵径＞叶长＞营养生长期。②茎瘤芥育种选择熟性晚、叶较长、横径宽、植株个体较大和茎/叶高的品种,可实现品种产量高、生态适应性强和瘤茎外观品质佳等三者的协调统一。更多还原

【Abstract】 The variability and correlation of main characters were analyzed by use of 14 resources.The results showed that the variability of tumor- ous stem yield was the largest,and vegetation duration the smallest.The variability of 9 characters were arranged from large to small:tumorous stem yield,whoh plant weight,ratio of stem and leaf,tumorous stem index,horizontal length,leaf width,vertical length,leaf length and vegetation dura- tion.High yield breeding combining with strong ecological adaptability and good appearance quality should be largely based on tumorous stem di- ameter,whole plant weight,later maturity,higher ratio of stem and leaf and longer leaves.更多还原
