转基因黄河鲤生长速度快、饵料转化效率高，具有巨大的应用前景。但转基因鱼群体仍然存在不同程度的生长性状分离，有待开展进一步的基因组选育。本研究将针对生长性状发生显著分离的家系，运用极端分离群体测序和表型/基因型关联分析方法，筛选生长性状分离相关基因。藉此，在子代群体中选择合适基因型携带者，构建繁育群体，培育生产性能稳定、表型性状均一的转基因黄河鲤品系。同时，将结合转录组和生物信息学研究，深入解析相关基因的功能和网络调控机制。

Transgenic Yellow River Carp has the characteristics of fast growth rate and high feed conversion efficiency, so it has great application prospects. But the transgenic Yellow River Carp population still has the characteristics of the different degree of growth traits, which needs to be further developed. In view of the families which have the significantly separated growth trait, we will use the methods of bulked segregate analysis and genotype/phenotype correlation analysis to screen the growth trait related genes. In this way, we can select the appropriate genotype carriers in the progeny population, construct the breeding population, and breed the transgenic Yellow River Carp strains with stable production performance and uniform phenotypic properties. At the same time, we will combine the transcriptome and bioinformatics research to thoroughly analyze the function of the related genes and the mechanism of network regulation.
