Embodiment Construction

[0032] The experimental methods used in the following examples are conventional methods unless otherwise specified. The materials and reagents used in the following examples can be obtained from commercial sources unless otherwise specified. All primers in the following examples were synthesized by Nanjing Jisi Huiyuan Biotechnology Co., Ltd. The fish used in the experiment of the present invention are all obtained from the fish genetics and breeding laboratory of the School of Marine Science and Engineering of Nanjing Normal University.

[0033] The patented SNP molecular markers of the present invention are derived from the genetic map of the F1 offspring constructed by our laboratory of Peeled catfish, and then obtained through the QTL positioning of economic traits (low dissolved oxygen tolerance and plumpness):

Abstract

The present invention discloses a SNP molecular marker for identifying the low dissolved oxygen tolerance and plumpness of Pelvis varchenii and its application. The sequence of the SNP molecular marker is shown in SEQ ID NO: 1, and the SNP molecule The marker is located at the 68th position of the nucleotide sequence of SEQ ID NO: 1, and its base is G or A. Through the SNP molecular marker and KASP primer set disclosed in the present invention, it can be used to identify or assist in the identification of low Dissolved oxygen tolerance and plumpness, the SNP markers disclosed in the present invention can be effectively applied to parental selection and molecular marker-assisted breeding of peltrelative catfish.

Description

technical field [0001] The invention relates to a SNP molecular marker for identifying low-dissolved oxygen tolerance and plumpness of Pelvis vacherius based on KASP technology and an application thereof, belonging to the technical field of aquatic animal genetics and molecular marker-assisted selection breeding. Background technique [0002] Pelteobagrus vachelli (Pelteobagrus vachelli) is the largest individual species in the genus Pelteobagrus (body weight is more than 1850g), and it is the two most economically valuable of the genus together with Pelteobagrus vachelli. Species. Currently, the new aquatic species hybrid yellow catfish "Huangyou No. 1" is a hybrid of yellow catfish as the male parent and yellow catfish as the female parent. It has fast growth, attractive body color, Strong disease resistance and other advantages. In the cultivation of new aquatic species, the most important link is parent selection, and the current new aquatic species hybrid yellow catfis...
