Embodiment 1

[0019] (1) The eggs were crossed with incomplete red-feathered male quail and chestnut-feathered female quail of Korean Longseong quail to produce the F1 generation; Quail is a mutant of the red-feathered quail.

[0020] (2) Select chestnut-feather male quail and chestnut-feather female quail from the F1 generation, and self-breed to produce the F2 generation; the quails hatched are female quails and chestnut-feather male quails, and the black-feather female quail accounts for 48.57%. Chestnut feather male quail accounted for 51.43%. Li Hong ratio was 1:1 (P>0.05).

[0021] (3) From the F2 generation, male quails with complete plumage characteristics were selected and crossed with pure-line Chinese yellow-feather female quails to produce F3 generation; F3 generations were all complete plumage quails.

[0022] (4) Perform cross-fixation and test crossing of the selected male quails and female quails with complete feathers, so that the feathers can be inherited stably, colonie...

Embodiment 2

[0024] (1) The eggs are crossed with incomplete red-feathered male quail and chestnut-feathered female quail of Korean Longseong quail to produce the F1 generation; the F1 generation is chestnut-feathered male quail and chestnut-feathered female quail;

[0025] (2) select chestnut-feather male quail and chestnut-feather female quail from the F1 generation, self-breed, and produce the F2 generation;

[0026] (3) Select Chinese yellow-feathered male quail and Korea Longcheng female quail to hybridize, the male quail of the first generation is chestnut-feathered, the female quail is yellow-feathered, and the separation ratio is 1:1, and then the Chinese yellow-feathered female quail obtained with From the F2 generation, the male quail with complete plumage characteristics was selected and crossed to produce the F3 generation;

[0027] (4) Perform cross-fixation and test crossing of the selected male quails and female quails with complete feathers, so that the feathers can be inhe...

Abstract

The invention relates to a method for cultivating a red-feathered egg quail strain. The method comprises the following steps: (1) hybridizing incomplete red-feathered male egg quails with maroon-feathered female quails in Ryongsong, North Korea and producing an F1 generation; (2) selecting maroon-feathered male and female quails from the F1 generation, selfing and producing an F2 generation; (3) selecting female quails with complete red-feathered features from the F2 generation, hybridizing with yellow-feathered male quails and producing an F3 generation; (4) performing cross fixation and test cross on selected complete red-feathered male and female quails to enable the red-feathered quails to be subjected to stable inheritance, group extension and cultivation and cultivating the red-feathered egg quail strain. The method provided by the invention has the benefits that through a ternary hybridization method, the red-feathered egg quails are produced, the survival rate during the brooding period can reach 95 percent or above, the egg laying rate is high, and the red-feathered egg quails have different features as compared with other feather colors of strains; moreover, the red-feathered egg quail strain cultivated by the method can automatically sex with pure strains of Chinese white-feathered quails, and the accuracy rate can reach 100 percent. The method has an important significance in researching quail feather color mutants and disclosing the research and the application of a quail locus.

Description

technical field [0001] The invention relates to a method for cultivating quail strains for eggs, and relates to the technical field of quail breeding. Background technique [0002] Compared with meat quail, egg quail lays eggs earlier and has better egg production performance, and the egg-to-feed ratio is lower than that of meat quail. It has the advantages of fast growth, early maturity, more egg production, less material consumption, and short production cycle. . [0003] At present, the quail strains for eggs in my country are relatively single, and the main feather color strains are Korean Longcheng quail, Beijing white-feather quail and Chinese yellow-feather quail. There are problems such as lack of genetic resources, population degradation and unreasonable structure of production groups. [0004] Feather color is a main feature for distinguishing quail seedlings. According to different color systems, it can be divided into colorless feathers and colored feathers. Col...
