Taiwan Black Goat is an important indigenous farm animal in Formosa Island. The conservation population was in Hengchung Branch of LRI since 1987. However, the information of genetic diversity of Taiwan Black Goat was very limited. To study the genetic diversity, a set of 12 microsatellite markers recommended for goat in FAO¡¦s DADIS MoDAD programme were utilized. The study was carried out on 40 animals to generate genotype data. Except ETH10, all the microsatellites were polymorphic with average allelic number 3.8, ranged from 2 to 6 per locus. There were 42 alleles detected in total. The observed heterozygosity of the population ranged from 0.262 to 0.714, and the average observed heterozygosity was 0.483. The expected heterozygosity ranged from 0.357 to 0.674, and the average expected heterozygosity was 0.502. The estimated polymorphic information content (PIC) was 0.434. In 12 markers, ten markers were not highly informative with PIC less than 0.5 and one marker ETH10 had only one allele detected. Therefore, geneticist should be aware of genetic diversity of Taiwan Black Goat.
