Abstract: The genetic polymorphism of Yangxian artificially reared 43 crested ibises (Nipponia nippon) was firstly investigated by RMAPD (random microsatellite amplify polymorphic DNA) marker. The results showed that RMAPD was more stable and polymorphic than RAPD. 2147 bands were amplified by 12 pairs of primers,of which 93 bands had polymorphisms. The band sharing frequency and the genetic diversity index were 0.718 and 3.664, respectively, indicating that the genetic structure of crested ibis population was simple and poor genetic variations existed in crested ibis population in Yangxian. It is imperious to protect the genetic diversity of crested ibis population.
