Abstract

The invention belongs to the technical field of molecular genetics, and particularly relates to an SNP (Single Nucleotide Polymorphism) molecular marker for identifying the age-round shearing amount of alpine merino and application of the SNP molecular marker. The SNP molecular marker is located at the 20077683th nucleotide site G / C mutation on the fifth chromosome of the international sheep reference genome Oarv4.0 version. The invention further relates to a specific primer pair for detecting the SNP molecular marker by using a PCR technology, a kit containing the primer pair and a nucleotide polymorphism detection method, and compared with a traditional detection method, the technology has the advantages of high accuracy, high detection speed, low cost, easiness in result judgment and the like. SNP locus detection is used for carrying out early selection of the annual shearing amount of the alpine merino sheep, shortening the breeding period and accelerating the breeding process, an early selection technology of the annual shearing amount of the alpine merino sheep is established, the breeding time of the excellent character of the annual shearing amount of the alpine merino sheep is shortened, the breeding cost is reduced, and the application value is very high.

Description

technical field

[0001] The invention belongs to the technical field of molecular genetics, and in particular relates to a SNP molecular marker for identifying the annual shearing amount of Alpine Merino sheep and its application. Background technique

[0002] Wool refers to a layer of textile-worthy fibers covering the surface of the sheep's body and is a derivative of the skin. Wool is the main raw material of wool spinning industry, accounting for about 97% of wool spinning raw materials, and is mainly used to process clothing fabrics, wool, blankets and other products. In wool production and breeding practice, wool traits are important economic traits, mainly including hair length, wool yield, average fiber diameter, bending, breaking strength, elongation, net wool rate, shearing amount and other indicators. Weaving products and economic benefits are closely related. Due to population growth, demand for wool has exceeded supply. As market demands change, producing high...
