Abstract: In order to reveal the genetic variation in Mingguang small-ear pig population and provide the genetic background for its preservation and utilization， 65 individuals sampled from the breed were assayed by using 76 microsatellite loci located on swine′s 19 pairs of chromosomes. A total of 343 alleles were detected， the number of alleles varied from 2 to 9 and the number of effective alleles from 1.223 9 to 4.807 9， giving mean allele number at each locus was 4.513 2±1.205 5 and effective allele number was 3.216 9±0.773 6. The mean observed heterozygosity， expected heterozygosity and polymorphism information content(PIC) in the population were 0.944 2±0.159 5， 0.668 5±0.094 5 and 0.610 3±0.108 3， respectively. The results indicated that the genetic variation was rich in this population.
