Breeding method of high-yield variety with green (black or yellow) shank and recessive white feather

Abstract

The breeding process of high-yield variety with green (black or yellow) shank and recessive white feather includes the following steps: hybridization between recessive white feather chicken or green (black or yellow) shank and recessive white feather chicken and high-yield brown-shell egg or white-shell egg chicken to obtain F1 generation hybrid individuals; selfing reproduction of F2 generation with the F1 generation and selecting green (black or yellow) shank and white feather chicken W; test crossing green (black or yellow) shank yellow chicken with W, selecting green (black or yellow) shank and pure white feather hem and cock and self-reproduction to produce Y; repeated test cross and selection to obtain recessive white feather chicken individuals; and self-reproduction to expand colony, constitute genealogy and obtain new chicken variety of high-yield variety with green (black or yellow) shank and recessive white feather.

Description

technical field

[0001] The present invention relates to a method for breeding chickens, in particular to a method for cultivating green-legged recessive white-feathered chickens, and also to a method for cultivating black-legged recessive white-feathered chickens, and a method for cultivating yellow-legged recessive white-feathered chickens The method belongs to the field of breeding technology. Background technique

[0002] There are many local chicken breeds in my country, and some of these breeds have the following characteristics: beautiful appearance, yellow or ephedra feathers, cyan, black or yellow shank and beak, tender meat, delicious meat, mellow soup and rich nutrition . At present, in the matching production of native chickens with yellow (hemp) feathers in my country, the female parent's matching line mostly adopts fast and large recessive white feathers imported from abroad, so there are the following problems: (1) the introduction cost is high; (2) it is easy ...

Embodiment 1

[0026] The breeding method of yellow shank recessive white feather chicken, the method comprises the following steps:

[0027] (1) Using the yellow-shank recessive white-feathered chicken isolated from local yellow chicken or Ma chicken to cross with high-yield brown-shell hens to obtain F1 generation hybrid individuals;

[0028] (2) The F1 generation self-breeds the F2 generation; from the F2, the W1 pure white feather chicken with yellow shanks is selected;

[0029] (3) Testcross the pure line of Sanhuang chicken with W1, eliminate the dominant white feather individuals and other colored feather individuals isolated from W1, and select male and female chickens with pure white feathers of yellow shank, and then produce Y1 by self-propagation ;

[0030] (4) The Y1 produced in the above-mentioned step (3) is subjected to test crossing and breeding for (multiple) times according to the method of step (3), and the recessive white feather individuals after the test cross breeding...

[0032] The breeding method of yellow shank recessive white feather chicken, the method comprises the following steps:

[0033] (1) use the yellow-shank recessive white-feathered chicken isolated from the local yellow chicken or Ma chicken to cross with the white-shell layer hen to obtain the F1 generation hybrid individual;

[0034] (2) The F1 generation self-breeds the F2 generation; from the F2, the W1 pure white feather chicken with yellow shanks is selected;

[0035] (3) Testcross the pure line of Sanhuang chicken with W1, eliminate the dominant white feather individuals and other colored feather individuals isolated from W1, and select male and female chickens with pure white feathers of yellow shank, and then produce Y1 by self-propagation ;

[0036] (4) The Y1 produced in the above-mentioned step (3) is subjected to test crossing and breeding for (multiple) times according to the method of step (3), and the recessive white feather individuals after the test cross breed...

[0038] The breeding method of black shank recessive white feather chicken, the method comprises the following steps:

[0039] (1) Using black shank recessive white feather chickens isolated from local yellow chickens or Ma chickens to cross with high-yield brown shell hens to obtain F1 generation hybrid individuals;

[0040] (2) The F1 generation self-breds the F2 generation; from the F2, selects the black shank pure white feather chicken W2;

[0041] (3) Testcross W2 with the pure line of black shank yellow chicken or Ma chicken, and eliminate the dominant white feather individuals and other colored feather individuals isolated from the W2 generation, and select black shank pure white feather individual male and female chickens , and then produce Y2 by self-propagation;

[0042] (4) Y2 in the above-mentioned step (3) is subjected to test crossing and breeding for (multiple) times by the method of step (3), and the black-leg recessive white feather individuals after the test ...
