The chromosome number is 2n=96, belonging to hexaploid species (2n=6x=96), and the morphological difference is not obvious among the 96 chromosomes. All the chromosomes are metacentric and submetacentric. Relative length ratio of the longest to the shortest chromosomes is 2.10. There is no satellite chromosome in all the 96 chromosomes. The karyotype formula is 2n=96=60m+36sm, the karyotype type is 2B, a higher karyotype evolution.

The cytogenetics of interspecific hybrids among the four cultivated cotton species were studied in this paper and results are as follows: The diploid interspecific hybrid (G. arboreum×G. herbacium) F〓 had a four-chromosome-ring at the meiotic metakinesis. The synapses of tetraploid hybrid (G. hirsutum ×G. barbadense) F〓 was found to be regular, which mainly formed bivalents, sometimes some univalents, multivalents and chromosome bridge.
