Abstract: In this study, Jinghai Yellow chicken was used to analyze ACVR1 gene polymorphisms by PCR-SSCP and DNA sequencing method. As a result, there was one mutation site(G20190A) in Jinghai Yellow chicken. Three genotypes were detected(AA, AB, BB), and the frequencies of allele A and B were 0.9075 and 0.0925. For the reproductive performance, BB genotype in open weight was significantly higher than AA genotype (P<0.01), however AA genotype in 300 days of age weight was significantly higher than BB genotype (P<0.05). It implied that ACVR1 gene might have a fixed effect on growth and reproductive effect in Jinghai Yellow chicken.

Key words: Jinghai Yellow chicken; ACVR1 gene; polymorphisma
