Embodiment 1

[0028] The present embodiment provides a method for cultivating the new strain of the green-footed recessive white-feather dwarf broiler, comprising the following steps:

[0029] (1) 20 genotypes were ccZ idDw Z idDw of green-footed recessive white-feathered normal roosters with 35 genotypes CCZ iddw W's green-footed colored-feather dwarf hens were bred to obtain F1 generation, of which the genotype of the F1 generation rooster was CcZ idDw Z iddw , the number is 63, and the hen genotype is CcZ idDw W, the quantity is 87;

[0030] (2) The F1 generation of roosters and hens are mated to produce the F2 generation, and the genotype of the F2 generation rooster is CCZ idDw Z idDw , CCZ idDw Z iddw , CcZ idDw Z idDw , CcZ idDw Z iddw , ccZ idDw Z idDw and ccZ idDw Z iddw , the corresponding numbers are 45, 52, 86, 90, 50 and 48 respectively, and the hen genotype is CCZ idDw W. CCZ iddw W. CcZ idDw W. CcZ iddw W. ccZ idDw W and ccZ iddw W, the corresponding qua...

Embodiment 2

[0035] (1) 15 genotypes were ccZ idDw Z idDw of green-footed recessive white-feathered normal males with 25 genotypes of CcZ iddw The green-footed heterozygous colored-feather dwarf hens of W were bred to obtain the F1 generation, and the genotypes of the F1 roosters were CcZ, respectively. idDw Z iddw and ccZ idDw Z iddw , the corresponding numbers are 28 and 25, respectively, and the hen genotype is ccZ idDw W and CcZ idDw W, the corresponding quantities are 34 and 39 respectively;

[0036] (2) Select the genotype in the F1 generation as ccZ idDw Z iddw The green-footed recessive white-feathered normal rooster with genotype ccZ idDw W's green-footed recessive white-feather normal hens were bred to obtain the F2 generation, and the genotypes of the F2 roosters were ccZ idDw Z idDw and ccZ idDw Z iddw , the corresponding numbers are 42 and 48, respectively, and the hen genotype is ccZ iddw W and ccZ idDw W, the corresponding numbers are 63 and 61 respectively; ...

Embodiment 3

[0040] The only difference between Example 3 and Example 1 is the number of males and hens for cross, backcross, cross and purebred, and other operations are the same.

[0041] (1) 30 genotypes were ccZ idDw Z idDw of green-footed recessive white-feathered normal males with 48 genotypes CCZ iddw W's green-footed colored-feather dwarf hens were bred to obtain F1 generation, of which the genotype of the F1 generation rooster was CcZ idDw Z iddw , the number is 78, and the hen genotype is CcZ idDw W, the quantity is 109;

[0042] (2) The F1 generation of roosters and hens are mated to produce the F2 generation, and the genotype of the F2 generation rooster is CCZ idDw Z idDw , CCZ idDw Z iddw , CcZ idDw Z idDw , CcZ idDw Z iddw , ccZ idDw Z idDw and ccZ idDw Z iddw , the corresponding numbers are 57, 68, 109, 120, 64 and 61 respectively, and the hen genotype is CCZ idDw W. CCZ iddw W. CcZ idDw W. CcZ iddw W. ccZ idDw W and ccZ iddw W, the corresponding quant...

Abstract

The present invention relates to a method for cultivating a new strain of broiler chicken with green-leg recessive white feathers. The breeding method is to mate a rooster with recessive white feathers with green feet and a dwarf hen with colored feathers to obtain the F1 generation, and the F1 generation The rooster and the hen are mated to produce the F2 generation, and the F2 generation is used to mate with the normal rooster with blue-legged recessive white feathers and the normal-sized hen, and the F2 generation roosters with dwarf hens are selected from the F2 generation with blue-legged recessive white feathers. The hens are mated to obtain the F3 generation, and the green-legged recessive white-feathered dwarf cock and the green-footed recessive white-feathered dwarf hen are used for pure breeding in the F3 generation to obtain the new broiler strain. The new strain of blue-legged recessive white-feathered dwarf broiler fully utilizes the advantages of sex-linked recessive dwarf genes, reduces feed consumption, saves breeding space and improves feed conversion rate. Further, when the obtained green foot recessive white feather dwarf broiler line is mated with roosters of different feather color varieties, the feather color of the offspring is consistent with that of the male line.

Description

technical field [0001] The invention belongs to the field of broiler seed production, and particularly relates to a method for cultivating a new line of dwarf broiler chickens with green-footed recessive white feathers. Background technique [0002] Broiler chickens are the most common poultry species raised by humans. Domestic chickens originate from wild jungle fowls and have been domesticated for at least about 4,000 years, but chicken and eggs did not become mass-produced commodities until around 1800. The rapid growth of broilers is mainly due to the continuous optimization and improvement of chicken breeds. Many domestic and foreign breeding companies and scientific research institutions have long been engaged in the research and selection of broiler breeds, and have continuously cultivated new breeds with excellent characteristics. In recent years, market demand has promoted the development of local high-quality chicken breeding, and a good breeding material is crucia...
