Embodiment Construction

[0029] The method for cultivating breeding rabbits with high reproductive performance using the SNP-assisted selection breeding technology of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples.

[0030] The method for cultivating breeding rabbits with high reproductive performance using the SNP-assisted selection breeding technology of the present invention is used to locate and determine the dominant genomes of 10 teats, to cultivate specialized strains, and to establish high-performance meat rabbit matching lines. The method flow is as follows figure 1 shown.

[0031] Select paternal and maternal breeding rabbits with 8 teats and 10 teats respectively. There are 150 female rabbits and 50 male rabbits in each group. There are a total of 400 breeding rabbits in the two groups. Ears of breeding rabbits and their offspring are collected. Organization for gene sequence analysis. Based on this, a new method ...

Abstract

The invention belongs to the technical field of livestock breeding and relates to a method for breeding high-reproductive-performance breeding rabbits based on SNP. The method comprises the following steps that firstly, resource group establishing and character measuring are conducted, wherein 1, resource group establishing is conducted, and 2, character measuring is conducted; secondly, target SNP selecting and whole genome correlation analyzing are conducted, wherein 1, genome SNP finding and whole genome SNP chip customizing are conducted, 2, whole genome correlation analyzing and verifying are conducted, and 3, SNP gathering is conducted; thirdly, a BLUP method is conducted, wherein a marginal effect value is calculated based on the principles of economics, and the animal model BLUP method is used for studying rabbit breeding value comprehensive selecting indexes; fourthly, a new M-BLUP rabbit breeding method is conducted, wherein the genetic effect of significant SNP locuses is estimated, molecule marking and BLUP are combined, and the new M-BLUP rabbit breeding method is established; fifthly, the new M-BLUP rabbit breeding method is used for breeding the high-reproductive-performance rabbits. The SNP assistant selection breeding method is adopted, special strains can be bred, and a high-reproductive-performance meat rabbit matched system can be established.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry breeding, and relates to a breeding method for breeding rabbits with high breeding performance based on SNP. Background technique [0002] Traditional breeding mainly relies on phenotype selection (Phenotype selection). Environmental conditions, gene interaction, genotype-environment interaction and other factors will affect the efficiency of phenotypic selection. For example, the identification of disease resistance is affected by disease conditions, physiological conditions, and evaluation standards; the selection and identification of quantitative traits such as quality and yield are more difficult. The cultivation of an excellent variety often takes 7 to 8 years or even more than ten years. How to improve selection efficiency is the key to breeding work. [0003] The long-term breeding practice has continuously explored the use of genetic markers to improve the selection effic...
