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
The present invention relates to duck supporting is producing method for seed, relates in particular to the producing method for seed of the supporting system of phoenix head dummy egg duck, belongs to poultry genetic breeding technical field.
Technical background
China's duck varieties aboundresources can be divided into egg with duck, meat duck and dual-purpose duck according to its economic use.Along with the raising of expanding economy and living standards of the people, people can propose new target and requirement to the seed selection of duck varieties naturally.American-European in recent years with the important component part of show type aviculture as aviculture.State poultry associations such as Britain, the U.S., Canada very stress appreciative value or the special proterties of poultry.A phoenix proterties is as fancy points; Discovery is all arranged on chicken, duck, goose at present; Tufted duck appears at Britain the earliest, according to " things dark purple pearl " (bright yellow one positive 1591 works were apart from modern existing more than 400 year) record; The tufted duck of " there are high hair, white hair, black bone in the top " is arranged in China, and unfortunate this duck is lost already now.The sky, Zhengjiang City becomes livestock and poultry Co., Ltd in using as a servant with duck production of hybrid seeds process, has found that a small amount of tufted duck is individual, and this is significant with the economic use (ornamental value) that increases duck for saving this rare proterties.And China does not also form the reliable tufted duck seeding technique of a cover as yet at present, and this has also hindered tufted duck greatly and has cultivated process.
Summary of the invention
The object of the invention is to provide a kind of producing method for seed of the supporting system of phoenix head dummy egg duck that can fill the domestic gaps; Through reciprocal cross to normal type duck and phoenix head dummy duck, phoenix head dummy duck and phoenix head dummy duck; Find that the phoenix tau gene is dominant lethals control, is incomplete dominant lnheritance; According to this genetic development and experiment, obtained the producing method for seed of the supporting system of phoenix head dummy egg duck.
The producing method for seed of the supporting system of the said phoenix head dummy of the present invention egg duck, concrete production of hybrid seeds step is following:
(1) chooses numb plumage tufted duck (Aa) and decide duck (aa) hybridization, at F with the normal type gold
1Through family selection method the index of laying eggs of a phoenix drake (Aa) is selected in generation;
(2) with F
1An outstanding phoenix drake (Aa) of selecting and remain in generation is decided duck (aa) with the normal type gold and backcrosses F
2The Dai Fengtou duck is used to lay eggs and view and admire, and can obtain the present invention.
F in the said method step (1)
1An outstanding phoenix drake of selecting and remain in generation is that offspring's annual egg is higher than a phoenix drake of 200.
Use other high laying duckses among the present invention, also can obtain the present invention like Shaoxing duck as material, but the adaptability of Yin Jinding duck is good, therefore preferred gold is decided duck.
The supporting system of phoenix head dummy egg duck that the present invention cultivates not only has certain ornamental value, has increased the economic type of duck, and its egg laying performance is also higher, also saves and developed this rare proterties.

Embodiment
(1) utilize the reciprocal cross of normal type duck and phoenix head dummy duck, phoenix head dummy duck and phoenix head dummy duck, observation is thereafter for the head phoenix head performance of duckling and separate ratio.
Each hybrid combination offspring's of table 1 separation case
Like table 1, in tufted duck ♂ * tufted duck ♀ filial generation, phoenix head individuality is 1.69: 1 with the ratio of no phoenix head individuality; Also occur 113 and do not gone out the shell egg, do not gone out the shell egg to 113 and cut open inspection, found 74 exencephalys; Lack the part cranium, beak is also undesired.It is individual to include 74 deadly individualities in the phoenix head, and phoenix head individuality is 2.55: 1 with the ratio of no phoenix head individuality, meets 3: 1 through Chi-square Test.Explain that this proterties is a dominant inheritance, and dominance is isozygotied deadly.In tufted duck ♂ * normal duck ♀ and normal duck ♂ * tufted duck ♀ filial generation, phoenix head individuality was respectively 0.86: 1 and 0.85: 1 with the ratio of no phoenix head individuality, and Chi-square Test all meets 1: 1, explains, this proterties is autosomal inheritance.
(2) choose numb plumage tufted duck drake (Aa) and decide duck duck (aa) as production of hybrid seeds material with the normal type gold, numb plumage tufted duck comes from the sky, Zhengjiang City and becomes livestock and poultry Co., Ltd, and gold is decided duck and come from Zhenjiang aquatic bird research institute, and both carry out cross experiment.
(3) at F
1Through family selection method (Wang Jinyu, Chen Guohong, 2003, publishing house of Southeast China University) index of laying eggs of a phoenix drake (Aa) is selected in generation; (offspring's annual egg is higher than 200 a) phoenix drake (Aa) of selecting and remain outstanding.
(4) decide duck (aa) with an above-mentioned outstanding phoenix drake (Aa) with the normal type gold and backcross F
2The Dai Fengtou duck be used as egg with and view and admire (Fig. 1), a phoenix drake be used as meat with view and admire (Fig. 2).
Claims (2)
1. the producing method for seed of the supporting system of phoenix head dummy egg duck is characterized in that this producing method for seed carries out according to the following steps:
(1) chooses numb plumage tufted duck and normal type gold and decide duck hybridization, at F
1Through family selection method the index of laying eggs of a phoenix drake is selected in generation, the offspring's annual egg of selecting and remain is higher than a phoenix drake of 200;
(2) with F
1Outstanding phoenix drake of selecting and remain in generation and normal type gold are decided duck and are backcrossed F
2The Dai Fengtou duck is used to lay eggs and view and admire, and promptly gets.
2. the producing method for seed of the supporting system of phoenix head dummy egg duck according to claim 1 is characterized in that: the supporting system of phoenix head dummy egg duck that cultivates contains 75% gold and decides the duck blood relationship.
