Abstract：To quickly find out the variety characteristics of the new resources of Luokeng chicken,in this study,molecular assisted marker technology involving recessive white-feathered(TYR)allele and Z-linked dw allele were performed.Consequently,46 heterozygous recessive white-feathered individuals were detected,the frequency of the heterozygous recessive white-feathered allele in the F0 and F1 generation were 11%and 13.67%,respectively and no Z-linked dw allele individual were detected across 356 samples.Altogether,the potential recessive white-feathered heterozygotes were totally eliminated within one generation,thus laying a foundation for the further genetic protection of Luokeng chicken.
