Abstract: PCR and direct sequencing methods were used to analyze the entire mtDNA D-loop in Baiyi Black chicken and Xingyi Bantam. The D-loop of Baiyi Black chicken and Xingyi Bantam was 1231 bp,there were 26 variational sites, including 12 transitions and 14 transversions. The nucleotide composition of Baiyi Black chicken was A 27.096%, T 33.628%, G 13.117%, C 26.159%, and A 26.916%, T 33.409%, G 13.387%, C 26.288% of Xingyi Bantam. The genetic distance between two partridges was 0.0379. According to the calibrated rates of molecular evolution, they speciated about 1.9 million years ago.

Key words: Baiyi Black chicken; Xingyi Bantam; mtDNA D-loop; genetic diversity
