Abstract: In this study, the genetic diversity of 232 samples of superfine merino sheep were studied, by using eight microsatellite markers mapped to sheep chromosome 1 and chromosome 3. Allele frequencies(p), mean heterozygosity（H），polymorphisms information content(PIC), and average effective number of alleles（N）were calculated. And various phenoltype including wool fibre diameter（WFD), fibre diameter dispersion（FD-D), wool fibre absolute strength（WAS), wool fibre relative strength（WRS), wool strength disperse(WSD), wool natural length(WNL), wool extend length(WEL) and fibre waviness(FW) were measured in the flock. Correlation analysis of Microsatellite loci with wool phenotype showed: there were great correlation between microsatellite BL-4 and WEL,microsatellite KRT2-13 and WEL（P<0.01）， microsatellite Oarcp43 and WSD（P<0.01），microsatellite Bms1248 and WFD(P<0.01)，the correlation between microsatellite Fcb5 and FW was significant(P<0.05), microsatellite OarDB6 and WAS was significant(P<0.05).
