The breeding method of silkiefowl black bone new lines
Technical field
The present invention relates to a kind of breeding method of silkiefowl black bone, relate in particular to a kind of breeding method of silkiefowl black bone new lines.
Background technology
Silkiefowl black bone is a kind of outstanding chicken kind that originates in China, it has advantages such as outward appearance is beautiful, the bodily form is unique, meat meat flavour deliciousness, strong, the good raising of premunition, be the germ plasm resource of China's preciousness, but because the new lines of this kind is few, how sell, thereby caused the loss of germ plasm resource with purebred form.
Summary of the invention
The object of the present invention is to provide a kind of breeding method of silkiefowl black bone new lines.
For achieving the above object, technical program of the present invention lies in adopting a kind of breeding method of silkiefowl black bone new lines, this method may further comprise the steps:
(1) utilizes the supporting system of modern brown shell layer,, produce F1 generation with the silkiefowl black bone mating with golden gene (sex-linked gene);
(2) F1 produces F2 generation for male and female autocopulation;
(3) at the F2 silkiefowl black bone individuality that selection has red (jute) plumage feature in generation;
(4) utilize the male and female chicken with the middle feature of step (3) to carry out traversed by and fix, make it genetic stability, by expanding the group, test cross identifies that red (jute) plumage silkiefowl black bone new lines is promptly cultivated in seed selection.
Gene in the supporting system of modern brown shell layer with golden gene described in the step (1) can be A system, B system, AB system with golden gene.
Simultaneously, technical program of the present invention lies in adopting the breeding method of another kind of silkiefowl black bone new lines, this method may further comprise the steps:
(1) with the supporting system of modern brown shell layer,, produces F1 generation with the silkiefowl black bone mating with silver color gene;
(2) F1 produces F2 generation for male and female autocopulation;
(3) at the F2 silkiefowl black bone individuality that selection has white plumage feature in generation;
(4) utilizing in the step (3) the selected male and female chicken that goes out to carry out traversed by fixes, expand the group, A system, B system or AB by having the silver color gene in the supporting system of modern brown shell layer are that the male and female chicken carries out test cross therewith, identify, seed selection can be cultivated the white-feather silky chicken new lines with the heredity of silver color stable gene.
Gene in the supporting system of modern brown shell layer in the step (1) can be C system, D system, CD single cross system or China's native chicken breed with silver color gene.
Technical program of the present invention also lies in adopting a kind of method that forms a complete production network of silkiefowl black bone new lines, this method may further comprise the steps:
(1) utilizes the local yellow pockmarked feather chicken of the supporting system of modern brown shell layer or China,, produce F1 generation with the silkiefowl black bone mating with the golden gene that isozygotys;
(2) F1 produces F2 generation for male and female autocopulation;
(3) at the F2 silkiefowl black bone individuality that selection has red (jute) plumage feature in generation;
(4) utilize the male and female chicken with the middle feature of step (3) to carry out traversed by and fix, make it genetic stability, by expanding the group, test cross identifies that red (jute) plumage silkiefowl black bone new lines is promptly cultivated in seed selection;
(5) with the supporting system of modern brown shell layer,, produce F1 generation with the silkiefowl black bone mating with silver color gene;
(6) F1 produces F2 generation for male and female autocopulation;
(7) at the F2 silkiefowl black bone individuality that selection has white plumage feature in generation;
(8) utilizing in the step (7) the selected male and female chicken that goes out to carry out traversed by fixes, expand the group, A system, B system or AB single cross by having the silver color gene in the supporting system of modern brown shell layer are that the male and female chicken carries out test cross therewith, identify, seed selection can be accompanied the white-feather silky chicken new lines that brings out the heredity of silver color stable gene;
(9) cock of red (jute) plumage silkiefowl black bone of being cultivated with step (4), hen mating in the white-feather silky chicken of being cultivated with step (8) with silver color gene can be produced the new supporting system of required silkiefowl black bone.
The supporting system of modern brown shell layer with golden gene described in the step (1) can be modern laying hen A system, B system, AB single cross system with golden gene; The supporting system of modern brown shell layer that has the silver color gene in the step (5) can be C system, D system or CD single cross system with silver color gene.
Technical program of the present invention also lies in adopting the breeding method of another kind of silkiefowl black bone new lines, this method may further comprise the steps:
(1) utilizes the local yellow pockmarked feather chicken of the supporting system of modern brown shell layer or China,, produce F1 generation with the silkiefowl black bone mating with golden gene;
(2) F1 produces F2 generation for male and female autocopulation;
(3) at the F2 silkiefowl black bone individuality that selection has red (jute) plumage feature in generation;
(4) utilize male and female chicken to carry out traversed by and fix, make it genetic stability with the middle feature of step (3), by the expansion group, test cross, red (jute) plumage silkiefowl black bone new lines is promptly bred in seed selection;
The cock of red (jute) plumage silkiefowl black bone new lines of (5) being cultivated in the optional step (4) hybridizes with China purebred silkiefowl black bone, produces the silkiefowl black bone that the male and female chicken is red (jute) plumage.
The supporting system of modern brown shell layer described in the step (1) can be modern laying hen A system, B system, AB single cross system with golden gene.
Advantages such as the outward appearance that the silkiefowl black bone new lines of utilizing method of the present invention to cultivate has not only kept original silkiefowl black bone to have is beautiful, the bodily form is unique, meat meat flavour deliciousness, strong, the good raising of premunition, and by importing the gene of different cultivars chicken, made full use of this outstanding variety source, cultivated red (jute) plumage silkiefowl black bone new lines and had the white-feather silky chicken new lines of silver color stable gene heredity with golden gene.Cock with red (jute) plumage silkiefowl black bone new lines with golden gene is formed a complete production network with the hen with white-feather silky chicken new lines of silver color stable gene heredity, in its young generation, can be according to automatical sexing on feather color, cock is white plumage, and hen is reddish yellow fiber crops plumages.Cock can be used as the direct marketing of commodity meat chicken, and hen both can be used as the commodity meat chicken and sold, and also can be used as layer chicken and produces black-bone chicken egg.In addition, utilize the purebred silkiefowl black bone of cock and China of red (jute) plumage silkiefowl black bone new lines that breeding method of the present invention cultivates to hybridize, can also produce the silkiefowl black bone that the male and female chicken is red (jute) plumage, thereby greatly enrich the silkiefowl black bone germ plasm resource of China.
