Problems solved by technology

Therefore, based on the variation information of the mitochondrial D-loop region sequence to evaluate the genetic relationship of the variety and whether there is any introgression of other varieties, although the use of microsatellite molecular markers and the sequence of the mitochondrial D-loop region can accurately determine whether the variety is mixed with the lineage of foreign varieties , but these methods are complicated to operate, time-consuming, and costly, which is not conducive to popularization and application in production

[0045] Cobb Broiler Specific Sequence Large Population Verification

[0046] The unique haplotype sequence of the Kebao broiler chicken obtained in Example 1 is used as the standard for whether the local chicken is mixed with the lineage of the Kebao broiler chicken:

[0047] Congrong County Zhouyi Breeding Farm, Guangxi Lingyun County Chen’s Animal Husbandry Co., Ltd. Breeding Farm, Donglan Black-bone Chicken Original Breeding Farm, Guangxi Nanning City Fufeng Agriculture and Animal Husbandry Co., Ltd.

Abstract

The invention discloses an application of a Cobb broiler DNA barcode 'TCTACGGGC' in screening Cobb broilers, and the Cobb broiler DNA barcode is obtained by the screening method. SNP sites and haplotype sequences specific on 12S rRNA are screened from mitochondrial genes by a PCR direct sequencing method by use of bioinformatic analysis software, one DNA barcode sequence specific to the Cobb broilers is obtained by large-group verification, and the DNA barcode breaks through the defects of long detection period and high cost of traditional microsatellite molecular markers, can rapidly and conveniently detect whether the blood lineage of the Cobb broilers is mixed in local varieties and can be applied to verification analysis of Cobb broiler purebreds.

Description

technical field [0001] The invention relates to the technical field of molecular biology, in particular to a method for screening Kebao broiler DNA barcodes and the application of the DNA barcodes. Background technique [0002] Guangxi has rich germplasm resources of local chickens. Currently, there are 6 local chicken breeds in Guangxi listed in the China Poultry Breed Resources List, namely Guangxi Sanhuang Chicken, Xiayan Chicken, Guangxi Ma Chicken (Lingshan Fragrant Chicken and Lidang Chicken), Nan Danyao chicken, Guangxi black-bone chicken (Donglan black-bone chicken and Lingyun black-bone chicken), Longsheng Phoenix chicken. These local breeds in Guangxi have excellent meat and egg quality. Guangxi Sanhuang is a meat-egg variety. The number of chickens raised ranks first in the country for high-quality broilers. The annual production and sales exceed 350 million. The meat is tender and has a strong smell. Nandanyao chicken is a meat and egg variety with excellent cha...
