White-feather black-beak high-quality duck breeding method

The invention discloses a white-feather black-beak high-quality duck breeding method. The method comprises the following steps: (1) Liancheng white ducks and Cherry Valley ducks (SM3) are selected and subjected to hybridization, such that an F1 generation is obtained; (2) ducks with specific appearance characteristics and qualified weights before egg-laying maturity are selected from the F1 generation, and are subjected to crossing, such that an F2 generation is obtained; (3) ducks with specific appearance characteristics and qualified weights before egg-laying maturity are selected from the F2 generation, and are subjected to crossing, such that an F3 generation is obtained; (4) the selection and crossing procedures are continued to be circulated until all individuals in an obtained Fn generation have the appearance characteristics of white feather, black beak and black feet, and the weights before egg-laying maturity reach 2.2-2.5kg; (5) the Fn generation is adopted as a base population, and F line and M line breeding populations are established; the F line and M line are further selected with a family selection method; (6) the F line is adopted as a male parent, and the M line is adopted as a female parent, and an obtained offspring is the duck provided by the invention. According to the invention, on a basis that local duck advantages are ensured; growth speed is improved; feed conversion ratio is improved; and carcass weight is increased.
