Abstract: Fat deposition is always the key point of research. Many quantitative
trait loci have been mapped on porcine chromosome 13 at present. In this paper, we introduced quantitative trait loci and candidate genes correlated with fat deposition on this chromosome. We can quest for candidate genes for fat deposition by comparative genomics and positional candidate clone approach in future, and then do linkage analysis or association analysis to check the effects of candidate genes, and apply the study results to animal breeding at last. 

Key words: pig; chromosome 13; fat deposition; quantitative trait locus; candidate gene
