摘　　要：Cottons are the most important fiber crops in the world.The cotton genus Gossypium has 52 species,including seven allotetraploid species and 45 diploids.Four species were domesticated and remain as crops under cultivation today:the New World allopolyploid species G.hirsutum and G.barbadense(2n=52),and the Old World diploid species G.arboreum and G.herbaceum(2n=26).The primary cultivated species is Upland cotton(G.hirsutum L.),which accounts for more than 90%of global cotton fiber production.Cottons are the most important fiber crops in the world. The cotton genus Gossypiurn has 52 species, including seven allotetraploid species and 45 diploids. Four species were domesticated and remain as crops under cultivation today： the New World allopolyploid species G. hirsutum and G. barbadense （2n = 52）, and the Old World diploid species G. arboreum and G. herbaceum （2n = 26）. The primary cultivated species is Upland cotton （G. hirsutum L.）, which accounts for more than 90% of global cotton fiber production.
