Embodiment Construction

[0012] (1) Using the positive and negative crosses between normal ducks and crested ducks, and crested ducks and crested ducks, observe the head crest performance and separation ratio of its offspring ducklings.

[0013] Table 1 Separation of offspring of each cross combination

[0014]

[0015] As shown in Table 1, in the hybrid offspring of Crested Duck ♂×Crested Duck ♀, the ratio of crested individuals to non-crested individuals was 1.69:1. There were also 113 unshelled eggs and 113 unshelled eggs. A post-mortem examination revealed 74 exposed deformities, missing part of the skull and abnormal beak. Seventy-four lethal individuals were included in crested individuals. The ratio of crested individuals to non-crested individuals was 2.55:1, which was in line with 3:1 by chi-square test. It shows that the trait is dominantly inherited, and the dominant homozygous is lethal. In the hybrid offspring of Crested Duck♂×Normal Duck♀ and Normal Duck♂×Crested Duck♀, the ratios of creste...

Abstract

The invention discloses a method for breeding ducks in a crested laying duck synthetic line, which comprises the following steps of: (1) hybridizing a pocking-feather crested duck with a normal Jinding duck and selecting the egg-laying index of a crested drake through a family selection method in an F1 generation; and (2) backcrossing a selected excellent crested drake in the F1 generation with the normal Jinding duck, wherein a crested female duck in an F2 generation is used for egg laying and aesthetic enjoyment. The method plays an important role in rescuing rare crested ducks, improving the economic application and ornamental value of the ducks and promoting the breeding of the crested ducks.

Description

Technical field [0001] The invention relates to a breeding method for duck matching lines, in particular to a breeding method for crested laying duck matching lines, and belongs to the technical field of poultry genetic breeding. technical background [0002] my country's duck species are rich in resources, which can be divided into ducks for eggs, ducks for meat, and ducks for combined use according to their economic uses. With the development of economy and the improvement of people's living standards, people will naturally put forward new goals and requirements for duck breeding. In recent years, Europe and the United States have made exhibition-oriented poultry industry an important part of the poultry industry. The poultry associations of the United Kingdom, the United States, Canada and other countries emphasize the ornamental or specific characteristics of poultry. The crested trait as an ornamental trait is currently found in chickens, ducks, and geese. The crested duck...
