Embodiment 1

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

[0015] (1) black-feathered quails for cultivating eggs, the breeding method is first to use black-feathered quail mutant males and Korean chestnut-feathered females to crossbreed to produce the F1 generation; then select male and female quails with incomplete black feathers in the F1 generation cross to produce the F2 generation; then select male and female quails with complete black feathers in the F2 generation, perform cross-cross fixation and test crossing, so that the black feathers can be inherited stably, and through population expansion and selection, breed black-feather quail strains for eggs;

[0016] (2) using the yellow-feathered male quail and the black-feathered female quail for laying eggs to crossbreed to produce the first generation of hybrids, that is, the F1 generation;

[0017] (3) On the day when the young quail hatched, the male and female were ide...

Embodiment 2

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

[0025] (1) black-feathered quails for cultivating eggs, the breeding method is first to use black-feathered quail mutant males and Korean chestnut-feathered females to crossbreed to produce the F1 generation; then select male and female quails with incomplete black feathers in the F1 generation cross to produce the F2 generation; then select male and female quails with complete black feathers in the F2 generation, perform cross-cross fixation and test crossing, so that the black feathers can be inherited stably, and through population expansion and selection, breed black-feather quail strains for eggs;

[0026] (2) Using Beijing white-feathered male quail and black-feathered female quail for laying eggs to crossbreed to produce the F1 generation of hybrids;

[0027] (3) On the day when the young quail hatched, the male and female were identified according to the feather...

Embodiment 3

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

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

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 mating method for self-sexing quail for eggs, and belongs to the technical field of quail breeding. Background technique [0002] At present, the main feather color strains 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 form 4 kinds of binary self-sexing lines and 2 kinds of three-way self-sexing lines, which have wide application value in production. After the black feather mutant was found in the Korean quail hybrid population, the genetic mechanism of the black feather mutant gene and the mutation 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) were studied. Studies have confirmed that the gene h controlling the black feather trait is located on the autos...
