| 对2个选育群体（XY2012-JC-F2和XY2012-XP-F2）和未选育群体（YS2012-F1）的大黄鱼（Larimichthys crocea）子代养殖过程中的生长性状进行测量，比较其性状选育效果。结果显示，拟合4～13月龄选育群体F2代和未经选育F1代体重（W）与体长（L）的关系表明，3群体间存在差异；2个选育群体在后期生长高于未选育群体。分析其体长和体重，10～13月龄XY2012-JC-F2体长现实遗传力为0.228～0.364、体重现实遗传力为0.131～0.243，XY2012-XP-F2体长现实遗传力为0.193～0.265、体重现实遗传力为0.126～0.134。体长和体重的相关系数在0.857～0.981，13月龄大黄鱼体长和全长的相关系数最大达0.997，说明选育具有一定的作用，选育应结合家系选择和家系内选择进行。 |

| By comparing the growth trait of the offspring of three breeding populations of Larimichthys crocea, the second generation of two selective breeding populations （XY2012-JC-F2 , XY2012-XP-F2 ）and the first generation of the wild breeding population（YS2012-F1）, the breeding effects were analyzed. The results showed that the correlations of body length (L) and weight (W) for F2 and F1 were different based on the measurement results which fitting 4-13 month-old Larimichthys crocea. Growth rate of the selective breeding were higher than the wild population breeding at the later stage. Analysis of the body length and weight showed that realized heritability of body length for 10 to 13 months of XY2012-JC-F2 was 0.228 - 0.364 , realized heritability of weight was 0.131- 0.243; and for XY2012-XP-F2, realized heritability of body length and weight were 0.193-0.265 and 0.126-0.134 ,respectively. The correlation coefficient of body length and weight was 0.857-0.981, the maximum correlation coefficient of body length and body weight was for 13 month-old Larimichthys crocea with the value of 0.997. Results indicated that selective breeding had a certain role in the process of breeding. It was also suggested that family selection and within-family selection should be combined in the future breeding.
