| 摘 要： | 通过选择培育获得大口黑鲈群体选育子三代,对其选育效果进行初步评价。实验数据分析表明,经过三代的选育,大口黑鲈2个选育组在体长、体高和体重上均大于对照组,且差异极显著（P〈0.01）,选育组1和2的日增重率分别比对照组提高了25.32%和23.42%,平均每代的选育效应分别为8.44%和7.81%,而体重变异系数分别是26.8%和20.2%,相比对照组分别降低了9.8%和21.1%。试验结果表明,大口黑鲈的选育效果明显,F3代的生长性能有了显著性的提高,个体之间的生长速度更加趋于一致,同时,F3代仍具有较大的选育潜力,可继续对其进行选育。该研究为进一步通过选择育种培育大口黑鲈优良品种（系）奠定了基础。

| Abstract: | The study preliminary evaluated the growth rate and morphological characteristic of third genera-tion（F3）of largemouth bass through mass selection.The results showed that the growth traits,including body length,body height and body weight of two selection groups,were significantly larger than the control group（P〈 0.01）.Compared with control group,the daily growth rate of selection group 1 and group 2 was improved by 25.32% and 23.42%（P〈0.01）,respectively,and the average selection response per generation was 8.44% and 7.81%,respectively,while variation coefficient of body weight was reduced by 26.8% and 20.2% over the control group,respectively.All these results from above showed that selection response of the two selection lines of largemouth bass was remarkable,and the individual growth rate was improved and turned to be consistent in the selected population. |
