Abstract

The invention provides a primer group for culturing homozygous black feather chicken and a method for culturing the homozygous black feather chicken by using the primer group. The primer group comprises a first primer group, a second primer group and a third primer group, wherein the first primer group is used for detecting whether an MC1R gene is mutated or not; the second primer group and the third primer group are used for detecting whether retrovirus is inserted into a TYR gene to cause a recessive white feather gene or not. The culturing method has the advantages that by using the first primer group, the second primer group and the third primer group, and simultaneously detecting the MC1R gene and the TYR gene, the EE (corresponding to the MC1R gene) and CC (corresponding to the TYR gene) gene type black feather chicken are screened out, and are homozygotes, and the recessive white feather gene is removed; the white feature individual will not occur in the filial generation when the primer group is matched with other systems, and the uniformity of the black feather phenotype is ensured; the breeding material of the breeding enterprise can be well protected on the basis of ensuring the product uniformity of the breeding enterprise.
