In this paper,chromosomal karyotype of Abaga horse was studied by using the fibroblast cells culture method and conventional chromosome analysis techniques.The karyotyping of Abaga horse has been analyzed by standard and G- banding technique.The results showed that the diploid chromosome number of Abaga horse was 2n = 64.The chromosome karyotypes of male and female horse were 64,XY and 64,XX.The chromosome 1-13 is metacentric-submetacentric autosome;chromosome 14-31 is acrocentric autosome.Chromosome X is the second longest submetacentric chromosome and Y is the smallest acrocentric chromosome.Moreover,each chromosome of Abaga horse has some unique patterns of its bands,and there are some differences with the reported Araba horse. This is the first report of G- banding karyotype of Abaga horse in China.The karyotype generated in this study will provide the fundamental information for equine cytogenetics and diagnosis of genetic disease in Arab horses.
