| 摘要: |
| 结球甘蓝(Brassica oleracea var.capitata L.)是个幼苗春化型(Green plant vernalizaion)作物。根据幼苗春化低温感应性的不同、可将我国现有甘蓝品种分成四个不同的生态类群。本文对目前甘蓝 F1代杂交制种中,存在的双亲种株花期不迂或抽苔种株向营养生长逆转问题的原由,从品种生态上做了说明,并提出克服途径。 |

| Abstract: |
| The cabbage(Brassica oleracea var.capitata L.)is of the young green plant vernalization type.Based on the differences in low te- mperature requirement during vernalization,the cultivars of cabbage in China may be classified into four ecotypes.These are: 1.Northwest China late spring seeding group,e.g. Dotong Hua Zibai,Zhang Jiako Hua Zibai 2.North China early spring seeding group,e.g. Early bejing,Early danjing,D.T.409 3.Yangtze Valley autumn seeding group,e.g. Shanghai niou sincabbage,jing zau shenghuang m... |
