Description
Technical field
The present invention relates to a kind of chicken breeding method, relate in particular to a kind of Japanese instar chickling plumage look that can make accurately from the producing method for seed of other male and female.
Background technology
Since laying hen and meat chicken enter scale and specialized production, laying hen and plant chicken all require to differentiate male and female when an age in days, to alleviate feeding cost in the future.Current male and female discrimination method has two kinds, and the one, anal identification method, the 2nd, utilize plumage speed or plumage look from other.Anal identification method not only requires discriminating personnel to carry out long-term professional training, and labour intensity is large, resolution has varied with each individual, and that height has is low, and misoperation is easily hindered chicken.One Japanese instar chickling male and female is from not having plumage look and plumage speed from other dividing, wherein the most simply, to utilize sex-linked golden feather genes (s) silver color feather genes (S) to carry out plumage look from other the most fast, wherein s and S are allelomorph, and silver color plumage is dominant with respect to golden plumage, but and not exclusively.As shown in Figure 1, its basic principle and flow process are as follows:
Set up two strains being with isozygoty golden plumage and the silver color plumage that isozygotys first respectively, and maternal with silver color plumage system work, golden plumage is to make male parent, and in one age in days offspring, white person is public young, and golden person is that mother is young.
Research shows; because silver color plumage is incomplete dominance to golden plumage; so in the situation that lacking modifier gene; utilize the male and female of gold and silver look feather genes from rate is not high; conventionally can only reach between 90-95%; even lower (Kang Xiangtao etc. 1995, peaceful China 2008), cannot reach the effect that scale utilizes.
Applicant has applied for (application number: 201010183909.7 applyings date: 2010-05-27) disclose a kind of Japanese instar chickling plumage look of making accurately from the producing method for seed of other male and female; the method comprises the following steps: 1) proof gold look Colombia plumage cock and the hybridization of standard variety White Rock, hybridize to obtain F1 pure white feather cock; 2) F1 pure white feather cock backcrosses to public this hen of yellow plumage, and select and remain white plumage black tail cock and Bai Yu black tail hen; 3) silvery white plumage black tail cock and Bai Yu black tail hen are from numerous, and hen stays silvery white plumage black tail person, eliminate golden plumage individual; Cock stays typical Colombia plumage type individual, and carries out being measured with silvery white plumage black tail hen, eliminates the heterozygosis cock that occurs the typical Colombia of non-silvery white plumage type individuality in offspring.4) silvery white plumage black tail hen is mating with red Yufu system or yellow Yufu with golden feather genes, a Japanese instar chickling of producing, and white plumage type is cock, golden yellow plumage is hen; From not other rate, reach 100%.But in this patent, there is a difficult problem, in step 3), cock stays typical Colombia plumage type individual, genotype is iiCoCoSS or iiCoCoSs, and to carry out with genotype be that iiCoCoSW hen is measured, eliminate the individual iiCoCoSs of heterozygosis cock and the iiCocoSS that in offspring, occur the typical Colombia of non-silvery white plumage type individuality, be difficult to obtain the individual iiCocoSS of heterozygosis cock.
