Six hexaploids of Gossypium involving cultivated tetraploids and diploid species from D and B genomes were synthesised. The morphology of vegetative and floral parts, fertility and mean halo length of the hexaploids are presented. The hexaploids resembled their tetraploid parents in most of the vegetative characters but the flower characters were intermediate. The fertility was variable within the hexaploid and also between the hexaploids. Halo length was fairly high though the wild, lintless diploids had contributed 26 chromosomes to the genome of the hexaploid.
