SNP loci associated with hind tendon and monk head weight on chromosome 6 of meat Simmental cattle and their application

Abstract

The invention provides an SNP site related to the shank and beef knuckle weights on a No.6 chromosome of a simmental cattle for meat, and application of the SNP site. The SNP marked site is the 38576012 nucleotide site on the No.6 chromosome of the international cattle reference genome UMD3.1 version, and a basic group of the site is A or G. By optimizing dominant alleles of SNP, the dominantallele frequency can be increased generation by generation, meanwhile, the shank and beef knuckle weights of the simmental cattle for the meat can be increased, the cattle genetic improvement progressis accelerated, and thus economic benefits of beef cattle breeding are effectively increased.

Description

technical field [0001] The invention relates to a SNP site on the No. 6 chromosome of meat Simmental cattle related to hind tendon and monk head weight and its application. Background technique [0002] In recent years, with the improvement of people's living standards, the demand for high-quality beef consumption is also growing rapidly. Meat Simmental cattle are the main contributors to beef consumption in China, accounting for more than 50% of the stock of beef cattle in China. Therefore, it is of great significance to increase the beef production of Simmental cattle for meat to meet the demand of the domestic beef consumption market. Beef tendon is the muscle of the beef thigh, including the front tendon and the rear tendon. Because of its moderate hardness and regular texture, it is a good product for making lo-mei and is very popular among consumers. Niu Lin is the tender meat located on the knee of the cow. It is naturally round in shape, so it is also called "monk...
