Pelteobagrus fulvidraco growth characteristic related SNP locus, detection and application thereof

The invention discloses a pelteobagrus fulvidraco growth characteristic related SNP locus, which can be at the 2100th position from the 5' end of a GH gene shown as SEQ ID NO:1, and has a basic group of A or G, or can be at the 2285th position from the 5' end of the GH gene shown as SEQ ID NO:1, and has a basic group of T or C, or can be at the 2822nd position from the 5' end of the GH gene shown as SEQ ID NO:1, and has a basic group of A or G. The invention also screens out a primer for specific detection of the SNP locus. The SNP locus provided by the invention is closely related to the full-length character of pelteobagrus fulvidraco, can be effectively used for molecular mark assisted breeding of pelteobagrus fulvidraco, and then the growth rate is selected according to actual breeding needs to conduct early selection on a pelteobagrus fulvidraco breeding material, thus further improving the breeding efficiency and accuracy effectively. 本发明公开了种黄颡鱼生长特性相关的SNP位点，为SEQ ID NO：1所示GH基因自5'端起第2100位，其碱基为A或G；或者为SEQ I
