Abstract: The main gentic diversity have morphological level,chromosomal level,protein level and DNA levels, etc. The kinds of native chicken in china,study the genentic diversity not only can enhance biodiversity conservation, but the great significance in the origin, evolution, clasification, identification and genetic breeding. Since the 1980s, the rapid development of molecular biology techniques for the deterction genetic diversity provides a more direct and accurate method that directly analyzing DNA sequence changes in the level of detection of animal genetic diversity. DNA analysis method to be the most effective methods of genetic analysis, to avoid the inference based on genotype phenotype of error may arise. Research of the DNA molecular genetic diversity of china native chicken breeds in this paper, excavation the good genes for the native chicken breeds, and provied the reference for the native chicken breeds in molecular breeding and improving.

Key words: chicken; gentic diversity; research progress
