History

The name Pima was applied in honor of the Pima Indians, who helped raise the cotton on USDA experimental farms in Arizona in the early 1900s.
The first clear sign of domestication of this cotton species comes the Early Valdivia phase site of Real Alto on the coast of Ecuador (4400 BC) and from Ancon, a site on the Peruvian coast, where cotton bolls dating to 4200 BC were found. By 1000 BC, Peruvian cotton bolls were indistinguishable from modern cultivars of G. barbadense.
