Abstract
The karyotype of Gossypium bickii Prokh., a wild diploid species originated in Australia, was analysed in this article. The result showed that the karyotype formula of G. bickii was 2n=2x=26=20 m+6 sm and had no satellite chromosome. This further proved the taxonomical position of G. bickii as the only species of G genome in Gossypium.
