About
Gossypium hirsutum, also known as upland cotton or Mexican cotton, is the most widely planted species of cotton in the world. Globally, about 90% of all cotton production is of cultivars derived from this species. In the United States, the world's largest exporter of cotton, it constitutes approximately 95% of all cotton production. It is native from Mexico to Ecuador and northeast Brazil, the Leeward Antilles in the Caribbean and the Pacific (Fiji, Marianas, Polynesia and Revillagigedo Islands).
It is believed that Gossypium hirsutum was created when a wild Mexican cotton species mixed with the wild African species Gossypium herbaceum around 5–10 million years ago, producing a hybrid species with four pairs of chromosomes (totaling 52 chromosomes) via polyploidy.
