摘要: 为评估10 个不同地理来源草鱼群体(佛山群体、肇庆群体、荆州群体1、荆州群体2、荆州群体3、鄂州群体、益阳群体、长沙群体1、长沙群体2 和江苏群体)杂交后代的生长性能,对该10 个群体为亲本构建的15 个杂交组合进行同塘生长对比。对其4 月龄、7 月龄、8 月龄、10 月龄、12 月龄、15 月龄和18 月龄的体质量进行测量。以4 月龄体质量为协变量,运用协方差分析对不同杂交组合后代进行生长性能分析。结果显示,在18 月龄时荆州群体2♀×佛山群体♂杂交组合后代平均体质量最高,为1892.90 g,比其他杂交组合平均体质量分别高3.51%~32.36%。经多重比较分析结果显示,荆州群体2♀×佛山群体♂和荆州群体1♀×佛山群体♂杂交组合后代的体质量显著高于其他杂交组合(P<0.05)。生产上,应用这2 个具有生长优势的组合生产优质苗种进行推广,可大幅度提高渔民的经济效益,另外该结果可为快速生长草鱼核心群体的确定奠定基础。

Abstract: To assess growth performance of hybrid progeny of grass carps from ten different geographical origins (Foshan population, Zhaoqing population, Jingzhou population 1, Jingzhou population 2, Jingzhou population 3, Ezhou population, Yiyang population, Changsha population 1, Changsha population 2 and Jiangsu population), fifteen hybrid combinations were constructed and cultured in the same pond. Body mass was measured at the age of 4, 7, 8, 10, 12, 15 and 18 months. Using body mass at the age of 4 months as covariant, growth performance of hybrid progeny was analyzed by covariance analysis. The results showed that the average body mass of Jingzhou population 2♀×Foshan population♂ was 1892.90 g at the age of 18 months and was 3.51%~32.36% higher than that of other hybrid progeny. Multiple comparison analysis showed that average body mass of hybrid progeny of Jingzhou population 2 ♀ × Foshan population ♂ and Jingzhou population 1♀× Foshan population♂ were significantly higher than that of other hybrid progeny (P<0.05). Jingzhou population 2♀× Foshan population♂ and Jingzhou population 1♀×Foshan population♂ were the optimized choice to produce high quality fry. The results will lay foundation for seeking Ctenopharyngodon idella populations who have rapid growth.
