Embodiment 1

[0156] Example 1 Simplified Genome Sequencing Screening for Species-Specific SNPs / INDELs Markers in Minqing Maojiao Chicken

[0157] (one)

[0158] Samples for sample: including Minqing Maojiao Chicken (20), Jining Hundred Day Chicken (20), Langya Chicken (20), Shouguang Chicken (20), Wenshang Reed Chicken (20), Rugao Yellow Chicken (20), Minqing Maojiao Chicken (20), Taihu Chicken (20), Liyang Chicken (20), Xuhai Chicken (20), Longsheng Phoenix Chicken (20), Langshan Chicken ( 20), Huaibei Maji (20), half male and half female for each breed. 0.5-1.0ml of blood was collected from the wing vein, placed in an anticoagulant tube, and stored at -70°C.

[0159] Genomic DNA was extracted by the CTAB method, and the genomic DNA was digested with restriction enzymes EcoRI and NIaIII, and then sequence adapters were added to construct a small fragment library for GBS simplified genome sequencing.

[0160] In order to check the efficiency of enzyme digestion and facilitate subsequent...

Abstract

The invention relates to an identification method of poultry breeds, and particularly relates to an identification method of the Minqing Maojiao Chicken breed. On the basis of obtaining a group of specific genetic loci of the Minqing Maojiao Chicken through screening, the obtained genetic loci are further subjected to optimizing and screening, the specific loci with high identification rate of Minqing Maojiao Chicken are obtained through screening, and the specific loci obtained through screening can be used for combined identification, so that the accuracy is higher, and the obtained result is more reliable.

Description

technical field [0001] The invention relates to an identification method of poultry breeds, in particular to an identification method of Minqing Maojiao chicken breeds. Background technique [0002] Minqing Maojiao Chicken, commonly known as Minqing Local Chicken, Minqing Local Chicken, Maojiao Chicken, and Phoenix-tailed Chicken, is a dual-purpose local breed. The central production areas of Minqing Maojiao Chicken are Baizhong Town and Bandong Town in Minqing County, Fujian Province. In 2009, "Minqing Maojiao Chicken" was approved by the Poultry Professional Committee of the Ministry of Agriculture and recognized as a breed of livestock and poultry genetic resources; in 2014, "Minqing Maojiao Chicken" was included in the "National List of Animal Genetic Resources Protection". In recent years, with the efforts of all walks of life, the brand of Minqing Maojiao chicken has had a small influence. However, due to the low threshold of breeding technology, other local chicken ...
