In this study, the correlation between microsatellite marker polymorphism and wool fineness of sunitebactrian camel was analyzed. The results show that, the average effective allele number, heterozygosityand polymorphism information content of 17 microsatellite markers in sunite bactrian camel were 2.8913,0.6205 and 0.5602, respectively. The wool fineness of AB genotype of CMS36 locus was significantlyhigher than that of BB genotype (P<0.05). The wool fineness of AC genotype at YWLL44 locus wassignificantly higher than that of BD, BE and CE genotype (P<0.05). The wool fineness of AA and BCgenotype at YWLL 29 locus was significantly higher than that of AC genotype (P<0.05). The woolfineness of AB genotype at LCA33 locus was significantly higher than that of AC, AD and BC genotype(P<0.05). Therefore, CMS36, YWLL 44, YWLL 29 and LCA33 microsatellite markers can be used inmarker assisted selection of wool fineness of sunite bactrian camel.
