Embodiment

[0014] Among the traits involved in the present invention:

[0015] Crested is dominant relative to non-crested, and the dominant trait is controlled by the allele Cr;

[0016] White feathers are dominant over colored feathers, and the dominant trait is controlled by allele B.

[0017] In the present embodiment, the crested white feather duck breeding method is carried out according to the following steps, and its genetic map is as follows: figure 1 :

[0018] (1) Select male ducks with crested feathers (CrCrbb) and Liancheng white ducks (crcrBB) to breed to produce the F1 generation.

[0019] (2) in step (1), select and retain the white-feathered duck (CrcrBb) with the same crested head size to breed from the group, and produce the F2 generation;

[0020] (3) in step (2), select and stay the white-feathered duck (Cr_B_) and the non-crested duck (crcrbb) test cross with colored feathers with the crested character, and the progeny selects homozygous male and female ducks (Cr...

Abstract

The invention belongs to the technical field of poultry breeding and selection, and particularly relates to a crested white-feather duck cultivating method. The method includes the steps that crested colored-feather ducks and non-crested white-feather ducks are used as bases and hybridized to produce the F1 generation; white-feather ducks with the crested character are selected from the F1 generation, and collective reproduction is conducted on the white-feather ducks with the crested character to produce the F2 generation; test cross is carried out on white-feather ducks with the crested character in the F2 generation, homozygous male and female ducks are selected to conduct purebreeding; athwart cross fixation is conducted on the purebreeding group, breeding is closed, individuals with black spots in feather color and small crests are rejected, until all characters are stably inherited, and the new crested white-feather duck strain is cultivated. According to the created crested white-feather duck cultivating method, the crossbreeding means is used, the crested character is guided into the Liancheng white duck group, ducks with high and white feathers at the top are recovered after being previously lost in China, the valuable and rare character of crest is effectively protected, the domestic blank is filled up, and the viewing and admiring requirement of human is met.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, and in particular relates to a method for breeding crested white-feathered ducks. Background technique [0002] With the development of the economy and the improvement of people's living standards, people put forward new goals and requirements for the selection and breeding of duck breeds. In recent years, Europe and the United States have taken the exhibition-type poultry industry as an important part of the poultry industry. National poultry associations such as the United Kingdom, the United States, and Canada have attached great importance to the ornamental or specific traits of poultry. Provide a new landscape. But so far, no new strains or matching strains of ornamental ducks have been selected and bred in China. The crested duck is a mutant discovered by Yangzhou University and Zhenjiang Tiancheng Agricultural Technology Co., Ltd. during the research and development process of r...
