摘  要：
利用包括基因与环境互作的加性-显性遗传模型对6个花椰菜品种(系)完全双列杂交试验的2 a观察资料进行花球性状与植株性状的遗传效应与相关分析.结果表明,年份间的环境差异对亲本和F1的表现影响较小;单球重、球径、球高、可溶性固形物含量、蛋白质含量、总糖含量和VC含量等花球性状以加性效应为主,普通狭义遗传率较高(53.37%-74.45%),株高、株幅和叶片数等植株性状以显性效应为主,且具有较大的环境互作效应,互作狭义遗传率较高(11.79%-37.27%);花球性状与植株性状间的各效应协方差分析表明,成对性状间的相关同时受到遗传主效应相关与环境互作相关的影响,相关性质和大小因性状不同而异,在间接选择时可加以利用,有助于对这些性状进行同步改良.

摘  要：
An additive-dominant genetic model with genotype-environment(GE) interaction was employed to analyze genetic effect and correlation for head and plant traits in cauliflower,based on 2 year data from 6×6 diallel crosses.The results indicated that the effect of environmental deviation of different years on head and plant traits of parents and F1 was less.Head traits were mainly affected by additive effects for head weight,head diameter,head height,soluble solid content,protein content,sugar content and VC content,general heritabilities were higher ranging from 53.37% to 74.45%.However,plant traits were mainly affected by the dominance effects and genotype×environment interaction effects for plant height,plant spread width and leaf number,interaction heritabilities were higher ranging from 11.79% to 37.27%.Analysis of genetic covariance indicated that the correlation between the head and plant traits was affected by both the genetic main effects correlation and genotype×environment interaction effects correlation.There was more or less degree of correlation between the paired traits.The property and extent of the correlation varied with the paired traits.These correlations could be used in indirect selection breeding,would contribute to the simultaneous improvement of these traits in cauliflower breeding.
