摘　　要：对 7个花椰菜亲本进行不完全双列杂交 ,采用朱军提出的加性—显性遗传模型 ,对花椰菜花球的外观和营养品质性状进行遗传相关分析。结果表明 ,多数性状间存在显著的遗传相关 ,其中有些性状间存在显著的加性相关或显性相关 ,可在花椰菜选择育种和杂交育种中加以利用。Seven parents of cauliflower were used in incomplete disllel crosses. Genetic correlation analysis of exterior and nutrient quality traits of head in cauliflower was conducted, based on the genetic model of additive-dominance. The results indicated that genetic correlations were significant among the most of traits, additive correlations or dominance correlations were significant among some of traits, and the results could be effectively applied in selection and breeding of hybrid cauliflower.

关 键 词：花椰菜 外观品质 营养品质 加性相关 显性相关
