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.
