There are at least 17 indigenous wild cotton species in Australia, including 12 species (K genome) primarily distributed in the Kimberley area. These Kimberley cottons (2n = 2x = 26, KK) showed high pollen compatibility with cultivated tetraploids (G. hirsutum, G. barbadense; 2n = 4x = 52, AADD) when the tetraploids were used as female. The pollination between AD as female and K produced almost the same boll-set as intraspecific crossing, while the reciprocal crosses were unsuccessful.
