Abstract

Relating to the field of genetics, the invention provides a screening method and application of a Bian chicken molecular marker. The screening method of a Bian chicken molecular marker includes: conducting high-throughput sequencing detection on SNP marker, calculating genetic statistics, analyzing and comparing the genetic difference of Bianji group and other chicken breed groups, and screening out a Bian chicken molecular marker. The method provided by the invention alleviates the technical problems of high Bian chicken genetic differentiation research cost and low accuracy caused by lack ofefficient molecular biological method in existing Bian chicken breed conservation effect evaluation process, and reaches the technical effect of efficient and rapid screening of a molecular marker for Bian chicken breed conservation effect evaluation. The invention also provides a screening method of the Bian chicken molecular marker and application of the screened molecular marker, and alleviates the technical problems of lack of efficient molecular biological marker and screening method in Bian chicken research.

Description

technical field

[0001] The invention relates to the field of genetics, in particular to a method for screening molecular markers of chicken and its application. Background technique

[0002] Domestic poultry breeds are precious resources endowed by the natural ecological environment and different national cultures for thousands of years. During the breeding and domestication process for thousands of years, many excellent characteristics have gradually formed. Bian chicken is a special local breed in my country. It has the excellent characteristics of large body, heavy eggs, good meat quality, strong adaptability, roughness and cold resistance. It is native to the inner and outer areas of the Great Wall adjacent to the northern part of Shanxi Province in the Inner Mongolia Autonomous Region. Because the local people regard the Great Wall as the "side wall", it is called side chicken. In recent years, with the impact of introduced breeds and the migration of people from mount...
