ABSTRACT
1. Genetic variation in the chicken MC1R gene was analysed through bioinformatic methods after polymerase chain reaction (PCR) amplification and sequencing of the coding region of MC1R gene from 5 different populations with 4 plumage colours (black, grey plumage with black spots, yellow plumage with black spots, red). 2. A total of 11 novel variations were detected in Hebei chickens, of which 8 were non-synonymous. Allele distribution analysis showed that the wild-type e(+) (Brown Leghorn) allele was mainly found in Hy-Line Brown and Lohmann Brown, the dominant Extended black E(AY220304) allele was mainly found in Hebei chicken with black plumage, whereas the Buttercup (e(bc)) allele was rare. 3. Nucleotide diversity (π) within each colour strain of Hebei chickens (0·0047-0·0052) was significantly greater than that of Hy-Line Brown (0·0024) or Lohmann Brown (0·0043). 4. The results indicate that there is abundant polymorphism in the MC1R gene, especially in Hebei chicken, which was associated with its rich plumage colour diversity.
