Abstract

The invention provides a perch immunity-related SNP site and application thereof in breeding. By comparing CD63 genes of different families, the SNP site related to disease resistance is obtained, anda screening marker is provided for screening disease-resistant perches. The invention firstly provides the perch immunity-related SNP site, the SNP site is located at the 223 site of the perch CD63 gene with the nucleotide sequence of SEQ ID NO: 1, and the basic group of the SNP site is C or A. The invention further provides a PCR amplification or sequencing primer for detecting the SNP site. The perch immunity-related SNP site is obtained through screening, perch individuals with higher resistance to pathogenic bacteria can be screened out by detecting the SNP site, and therefore the genetic breeding process of perches is accelerated.

Description

technical field

[0001] The invention belongs to the field of genetic technology of molecular breeding, and more specifically relates to a squid immune-related SNP site and its application in breeding. Background technique

[0002] Perch (Lateolabrax japonicus) is a carnivorous wide-salt fish. As a migratory fish in warm-temperate clusters in coastal waters, it is the main economic fish in my country's coastal waters. Bass is mainly distributed in the western Pacific Ocean, the coast of China and freshwater bodies leading to the sea. There are many in the Yellow Sea and Bohai Sea, and it is one of the common economic fish. Bass meat is white and tender, fragrant, without fishy smell, and the meat is in the shape of garlic cloves. It is most suitable for steaming, braised in soy sauce or stewed soup. It is one of the common economic fishes that I have ever lived, and it is also a species for the development of marine aquaculture.

[0003] According to statistics, in 2017, t...
