Embodiment 1

[0033] In the present embodiment, the breeding method of the blue-shank recessive white-feathered chicken strain may further comprise the steps:

[0034] (1) Using the Qingshan recessive white feather chicken as the male parent and the white Laihang chicken as the female parent in the Gushi chicken population to perform crossbreeding to produce the F1 generation;

[0035] (2) The F1 generation is self-crossed to obtain the F2 generation, and the F2 generation of green shin and white feather male and female chickens are selected;

[0036] (3) Determination of the genotype of the F2 generation blue-shin and white-feather male and female chickens by AS-PCR method, specifically including the following steps:

[0037] ① Collection of samples

[0038] Take blood from the veins of the chicken wings with green shanks and white feathers selected from the F2 generation, add 1 / 3 anticoagulant, extract blood DNA with proteinase K method, and store the DNA samples in a refrigerator at 4°C...

Abstract

The invention discloses a breeding method for a blue-shank recessive white-feathered chicken strain, and belongs to the technical field of molecular breeding. The present invention adopts the method of molecular-assisted selection to identify the genotype of chicken dominant white feather locus, can quickly determine the genotype of the locus, and produce the blue shank recessive white feather chicken strain with genotype ii, which can effectively avoid test cross selection The tediousness of breeding, shortening the interval between generations, speeding up the breeding process, and reducing the cost of breeding. The blue-shin recessive white-feathered chicken strain bred by the method of the invention has tender meat, delicious meat and high production performance, and can be directly put into production as a commercial chicken, and can also be matched with the green-shin jute feather.

Description

technical field [0001] The invention specifically relates to a breeding method for a blue-shank recessive white-feathered chicken strain, and belongs to the technical field of molecular breeding. Background technique [0002] With the improvement of living standards, people's consumption concept has changed from the quantity type to the quality type. People's requirements for chicken meat quality are also getting higher and higher. Local chickens in my country have the characteristics of good meat quality, but their growth rate is slow and their feed conversion rate is low. Although foreign fast large broilers grow fast and have a high feed conversion rate, their meat quality is poor. In order to solve this problem, crossing foreign fast large broilers with domestic local high-quality broilers can not only improve the meat quality of foreign fast large broilers but also accelerate the growth rate and production performance of local high-quality broilers. However, due to t...
