[Research and application of animal genetic marker-assisted selection].

With the development of molecular and quantitative genetics and its related subjects, it made a great progress on the research about animal genetic marker-assisted selection (MAS). There were also some successful examples on the application of MAS to animal genetic improvement. The statistical method which using phenotypic, pedigree and genetic marker information to predict individual breeding values has already been developed. Many achievements were obtained from the researches, which carried on MAS relative efficiency and its affecting factors and selection schemes. The present paper reviewed some progresses of MAS research and discussed some problems about MAS application to animal breeding.
