Abstract

The invention discloses an SNP molecular marker related to buffalo growth traits. The molecular marker is located at the 14436th basic group of a buffalo DGAT2 gene NW_005783701.1, and the nucleotide sequence of the molecular marker is as shown in SEQ ID NO. 1; the basic group in the SEQ ID NO. 1 is A or G. According to the SNP molecular marker related to the buffalo growth traits, by screening molecular marker sites related to the buffalo growth traits, a molecular marker genetic resource library of buffalo breeding is enriched. By adopting the molecular marker to breed the Murrah buffalo, the accuracy of buffalo growth traitselection is greatly improved, and individuals carrying the dominant allelic genes should be reserved in breeding, so that the body length traits of the buffalo group can be improved, and the molecular marker can be used as a potential genetic marker.

Description

technical field [0001] The invention relates to the technical field of cattle breeding, in particular to a SNP molecular marker related to cattle growth traits and its application. Background technique [0002] Cattle breeding work refers to any work that can improve the quality of cattle from the genetic structure and increase the quantity and quality of products. The breeding of cattle breeds is to consolidate and improve excellent genes in the group, thereby creating a product with superior production performance. individuals, and the process of expanding the number of good individuals. Genetic improvement of economically important traits in cattle herds. Traditional breeding methods mainly rely on phenotypic selection without understanding their genetic background. [0003] Now, breeders have gradually transformed the improvement of target traits from phenotype selection to genotype selection theory, making full use of molecular breeding methods to carry out selection ...
