Embodiment 1

[0014] The quail self-sex matching method for eggs of the present invention comprises the following steps:

[0015] (1) cultivating black-feathered quails for eggs, the breeding method is to first use the male quails of the black-feathered quail mutants to cross with Korean chestnut-feather female quails to produce F1 generation; Cross to produce F2 generation; then select male and female quails with complete black feathers in the F2 generation, carry out cross-cross fixation and test cross, so that black feathers can be stably inherited, and through group expansion and breeding, breed black-feather quail strains for eggs;

[0016] (2) Utilize yellow-feather male quail and egg-use black-feather female quail to produce hybrid generation, namely F1 generation;

[0017] (3) On the day of hatching, the male and female quails are identified according to the feather color of the F1 generation. The male quail has incomplete black plumage and the female quail has light gray plumage. ...

Embodiment 2

[0024] The quail self-sex matching method for eggs of the present invention comprises the following steps:

[0025] (1) cultivating black-feathered quails for eggs, the breeding method is to first use the male quails of the black-feathered quail mutants to cross with Korean chestnut-feather female quails to produce F1 generation; Cross to produce F2 generation; then select male and female quails with complete black feathers in the F2 generation, carry out cross-cross fixation and test cross, so that black feathers can be stably inherited, and through group expansion and breeding, breed black-feather quail strains for eggs;

[0026] (2) Utilize Beijing white-feather male quail and egg-use black-feather female quail to produce hybrid generation, namely F1 generation;

[0027] (3) On the day of hatching, the male and female quails are identified according to the feather color of the F1 generation.

[0028] Its inheritance pattern is as follows:

Embodiment 3

[0034] The quail self-sex matching method for eggs of the present invention comprises the following steps:

[0035] (1) cultivating black-feather quail for eggs and gray-feather quail for eggs, wherein the breeding method of black-feather quail is to first utilize the male quail of black-feather quail mutant to cross with Korean chestnut-feather female quail to produce F1 generation; then select F1 generation The male and female quails with incomplete black feathers are self-bred to produce the F2 generation; then the male and female quails with complete black feathers in the F2 generation are selected for cross-crossing fixation and test crosses, so that the black feathers can be stably inherited. , cultivating black-feathered quail strains for eggs; the breeding method of gray-feathered quails for eggs is to first use the male quail mutants of black-feathered quails to cross with Korean chestnut-feather female quails to produce F1 generation; The male and female quails are s...

Abstract

The invention relates to five autosexing mating methods for laying quails, which respectively comprise: (1) F1 generation male quails produced by a yellow-feather male quail and a black-feather female quail have incomplete black feather, and female quails have light gray feather; (2) F1 generation male quails produced by a white-feather male quail and a black-feather female quail have incomplete black feather, and female quails have white feather; (3) F1 generation male quails produced by a gray-feather male quail and a black-feather female quail have black feather, and female quails have gray feather; (4) F1 generation male quails produced by a gray-feather male quail and a white-feather female quail have incomplete black feather, and female quails have light gray feather; (5) and F1 generation male quails produced by a white-feather male quail and a gray-feather female quail have incomplete black feather, and female quails have white feather. The autosexing precision of the method reaches 100%; the method can carry out the autosexing on the gray-feather quails and the Beijing white-feather quails in case of cross breeding and reciprocal cross; the method can automatically sex the quails immediately after birth, thereby simplifying the sexing means, reducing the cost and enhancing the efficiency; and the invention fully utilizes the genetic resources of quails in China and enhances the production efficiency of the quail hybrids.

Description

technical field [0001] The invention relates to a matching method for quails used for eggs and belongs to the technical field of quail breeding. Background technique [0002] At present, the main plumage lines in the production of egg quail in my country are Korean quail (wild type chestnut feather), Beijing white feather and Chinese yellow feather. These kinds of feather-colored quail can be composed of 4 kinds of binary auto-sex matching lines and 2 kinds of ternary auto-sex matching lines, which have a wide range of application values ​​in production. After the discovery of the black feather mutant in the Korean quail hybrid population, the genetic mechanism of the black feather mutant gene and the mutant black feather locus (H / h) and the sex-linked feather color locus B / b (albino locus) were successively investigated through hybridization experiments. ) and Y / y (yellow feather locus) interactions were studied. The study confirmed that the gene h that controls the black...
