Breeding method of new line of high-quality white-feathered black-billed yellow-shank duck

Abstract

The invention provides a cultivation method of new white-feather black-beak yellow-shin high-quality duck variety. The method includes the following steps: 1, conducting expanding propagation on white-feather superior mutation pure line; 2, selecting parents P; 3, allowing male cherry valley ducks and white-feather superior female ducks hybridized in a ratio of 1:10 to obtain generations F1, and selecting and remaining female colored ducks; 4, making white-feather superior male ducks mate with female colored ducks in the generations F1 to obtain generations F2, and selecting and remaining white-feather black-beak yellow-shin ducks high in growth rate; 5, conducting cross mating and fixing, expanding duck flocks and seed selection to obtain the new white-feather black-beak yellow-shin high-quality duck variety. The duck variety retains the characteristics of high meat quality of original khaki-campbell ducks. Due to white feather, slaughtered duck carcasses are more beautiful; beaks are black, accordingly the beaks can be used as marks of the slaughtered ducks and used for unique research on development and utilization of beak color, and the market competitiveness is strong. The cultivation method can be used for building a resource population used for studying the genetic mechanism of the feather color, beak color and shin color of ducks, and the innovative development of high-quality lean meat type duck industry is promoted.

Description

technical field [0001] The invention relates to the technical field of genetic breeding of poultry, in particular to a breeding method for a new strain of high-quality white-feathered black-beaked yellow-shank duck. Background technique [0002] At present, the meat duck market is mainly dominated by large-scale meat ducks, followed by ducks that are used for both eggs and meat. Due to the complex inheritance of the white feather gene of large meat ducks, the molecular genetic mechanism has not yet been clarified, and the F1 generation produced by crossbreeding large meat ducks with shelducks often appears as complex and changeable ducks with yellow beaks and yellow shanks. , affecting the market price. Only the Liancheng white duck in China has the reputation of "medicinal duck". The adult male duck has white feathers all over its body, its beak is flat and bronze-colored, its beak is dark green, and its shanks, webs, and toes are dark brown. , shanks, webs, and toes are ...
