Abstract

Genetic diversity of Chinese native chicken breeds was investigated using protein polymorphism, randomly amplified polymorphic DNA (RAPD), and microsatellite polymorphism. Imported broiler and layer breeds were also included in the analysis. The results from protein polymorphism did not show distinct differences between Chinese native chicken and imported broilers; however, there were small significant differences between these two types of chickens. The results from RAPD indicated that gene diversity within a population was large in Chinese native chickens, intermediate in broilers, and low in layers and that there were small differences between Chinese native chickens and both broilers and layers. A great difference between broilers and layers was observed. Microsatellite polymorphism data showed that genetic diversity was high in the Chinese native chickens and low in layers and that there was a close relationship between Chinese native chickens and broiler but a remote relationship between Chinese native chickens and layers. The wide genetic diversity of Chinese native breeds can meet different requirements of breeding for chicken quality in China.
