Abstract

The invention discloses a SNP site related to the rapid growth of largemouth bass, an identification method and application thereof. The SNP site is located at the 234th base of the largemouth bass cathepsin B gene sequence. The alleles of the SNP site are C and G, and there are three genotypes of CC, CG and GG. The largemouth bass The sequence of perch cathepsin B gene is shown in SEQ ID NO.1. The SNP site can be applied to the screening of fast-growing largemouth bass parents.

Description

technical field

[0001] The invention belongs to the technical field of molecular biology, and in particular relates to a SNP marker related to the rapid growth of largemouth bass, an identification method and application thereof. Background technique

[0002] Largemouth bass (Micropterus salmoides L.), commonly known as California perch, is native to North America. It has the characteristics of fast growth, low temperature resistance, delicious meat and easy fishing. It is one of the important freshwater cultured fish. Introduced from Taiwan to Guangdong Province in 1983, it is now cultivated in most parts of the country. However, at present, the largemouth bass cultured in my country is domesticated from wild species, lacks directional selection, and often selects small individuals and early sexually mature individuals as parents when the parents are kept, resulting in the germplasm of largemouth bass in my country. The decline is mainly manifested in the decrease of growth...
