Abstract: Single nucleotide polymorphisms (SNPs) of exon 5 of the myostatin (MSTN) gene were detected in the Bian chicken and two reference chicken populations (Jinghai and Youxi chickens) by PCR-SSCP. The relationship with growth traits in the Bian chicken was also analysed. Results showed that there exsited an insretion (TC) in the 8527—8528 bp of the exon 5 of the MSTN gene. Three genotypes (AB, AB and BB) were detected in the Youxi chicken, while the Bian and Jinghai chickens only displayed two genotypes (AA and AB). The allele A was the predominant allele in the three chicken breeds. The least square means analysis showed the differences of body weight between the two genotypes in the Bian chicken were nonsignificant (P>0.05).

Key words: myostatin (MSTN); Bian chicken; PCR-SSCP; growth traits
