| 摘 要： | 以23份茎瘤芥品种资源为试材,在晚播条件下对茎瘤芥15个数量性状的遗传力等遗传参数进行了估算.结果表明,广义遗传力的大小次序为营养生长期、瘤茎膨大期、茎/叶、菜形指数、瘤茎横径、瘤茎纵径、菜皮百分率、叶宽、瘤茎产量、瘤茎空心率、开展度、株鲜重、出苗至瘤茎膨大始期、叶长、株高;瘤茎空心率、茎/叶、菜皮百分率、瘤茎产量等性状遗传变异系数较大、遗传力和遗传进度均较高,在选育群体中进行选择和利用,其选择潜力大,选择有效,可望获得较大的遗传进展.

| Abstract: | Hereditary parameters of 15 quantitative characters were estimated after testing 23 local tumorous stem mustard varieties under late sowing condition in this paper.The results showed that order of broad heritability was vegetative duration,developmental duration,ratio of stem and leaf,tumorous stem index,horizontal length,vertical length,fur percentage,leaf width,tumorous stem yield,hollow heart percentage,spreading degree,whole plant fresh weight,emergence to developing beginning,leaf length and plant heig... |
