Abstract: To identify the genes that potentially influencing the phenotypic characteristics variation of wild animals was the main objective of evolutionary genetics related research. Coat color was one of the optimum models that were commonly used in investigation of genetic mechanism associated with formation of animal coat traits. In this study, genetic typing test of 62 wild boars with varied coat traits was conducted by using Illumina pig 60 k SNP chips. Based on the SNP typing results, the genes associated with the variation of wild boars coat traits were identified by genome-wide association study(GWAS). We found 6genome variation areas associated with wild boars coat traits, locating in SSC1(ALGA0001794,ASGA0006416), SSC2(ASGA0011559), SSC6(H3GA0018683), SSC7(ASGA0035535)and SSC14(ASGA0060641), respectively. The most significantly correlated SNP was found in SSC1 and located in the region of 27 899 596-27 899 696 bp(P =2.96 ×10^-5). Six susceptibility gene loci associated with coat color traits of wild boars were preliminarily identified, which provides a basis for the genetic mechanism associated with formation of varied coat color traits of wild boars.
