| 摘 要： | 半滑舌鳎是重要的经济鱼类，已经被广泛推广养殖，致力于养殖方面的研究开展了很多工作，但是对半滑舌鳎生长性状进行准确遗传评估的研究还未见报道。为了对生长性状进行准确的遗传参数估计，本次研究以80个半滑舌鳎家系为研究对象，对半滑舌鳎早期生长性状（包括个体全长、体宽和体质量）进行分析。另外还将鱼体底面纯白与否（命名为底面颜色）作为一个性状进行研究。结果表明，四个性状都属于中等遗传力（全长为0.210、体宽为0.259、体质量为0.268、底面颜色为0.362）。三个生长性状之间具有很高的遗传相关性（0.913-0.959），表明如果三个性状进行间接选择的话，将会取得较好效果。底面颜色性状与三个生长性状均为正遗传相关，相关系数在0.241-0.353之间，由此可知，对底面颜色进行选择时，可以加强生长性状的选择效果。通过家系育种值排序，初步筛选出了生长性状优良遗传背景丰富的16个全同胞家系，将作为亲鱼繁殖后代。本研究为半滑舌鳎优良品种的成功培育提供了重要基础资料。

| Abstract: | Half-smooth tongue sole (Cynoglossus semilaevis) is a commercially important fish species. There were no reports about accurate genetic parameters of growth traits in C. semilaevis, despite efforts aimed at the culture of this species. Therefore, the main goal of this study was to estimate the parameters for the early growth traits (total length, body depth and body weight) of C. semilaevis based on the data obtained from 80 families. The trait of fish with pure white bottom or not (named as the trait of bottom color) was also analyzed. All the heritabilities estimated for the traits were medium, which varied from 0.210 to 0.362. Genetic correlations among growth traits were highly positive, varying from 0.913 to 0.959, indicating that selection of one of the three traits would result in correlated increase in the others. Also, genetic correlations between bottom color and growth traits were positive and varying from 0.241 to 0.353, suggesting that selection for the bottom color can be utilized to enhance the selection of growth traits. In addition, fish from the top performing 16 full-sib families were selected as broodstock, based on the above analysis and the comparison of family breeding value. This research provides an important basic material to implement selective breeding in C. semilaevis. |
