Commercial cotton species

Commercial cotton fibres, used to manufacture cloth, are derived from the fruit of the cotton plant. The following species are grown commercially:

Noncommercial species

Many varieties of cotton have been developed by selective breeding and hybridisation of the above species. Experiments are ongoing to cross-breed various desirable traits of wild cotton species into the principal commercial species, such as resistance to insects and disease, and drought-tolerance.

Most wild cottons are diploid, but there is a group of five species from America and Pacific islands which are tetraploid, apparently due a single hybridisation 0.5 to 2 million years ago.[2] The tetraploid species are G. hirsutum, G. tomentosum, G. mustelinum, G. barbadense, and G. darwinii.
