Interpretive Summary: Cotton represents the single most important, natural fiber crop in the world. To protect the world-wide economic value of cotton fiber and cotton byproducts, coordinated efforts to collect and maintain cotton genetic resources have increased over the last 100 years. Preserved genetic resources provide a valuable insurance policy against current and future cotton diseases and crop vulnerabilities. Cotton breeders can use these genetic resources to develop new cultivars that overcome emerging crop vulnerabilities. This report provides information on the status and contents of eight major cotton germplasm collections present across the world. Based on the findings of this report, a number of classified cotton species are not maintained in these collections and several are underrepresented and vulnerable to extinction. This report presents several critical challenges and opportunities facing international efforts to enhance and preserve the world’s cotton genetic resources. Multi-national communication and collaboration are essential to protect, secure, and evaluate the global cotton germplasm resources. Without global, collaborative efforts the rarest and most unique cotton germplasm resources are vulnerable to extinction.

Technical Abstract: The cultivated Gossypium spp. (cotton) represents the single most important, natural fiber crop in the world. In addition to its fiber, the oil and protein portion of the cottonseed also represents significant economic value. To protect the world-wide economic value of cotton fiber and cotton byproducts, coordinated efforts to collect and maintain cotton genetic resources have increased over the last 100 years. The classified genetic resources of cotton are extensive and include five tetraploid species in the primary gene pool, twenty diploid species in the secondary gene pool, and twenty-five diploid species in the tertiary gene pool. This report provides information on the status and contents of eight major cotton germplasm collections present across the world. Based on the findings of this report, a number of classified Gossypium species are not maintained in these collections and several are underrepresented and vulnerable to extinction. This report presents several critical challenges and opportunities facing international efforts to enhance and preserve the world’s Gossypium genetic resources. Multi-national communication and collaboration are essential to protect, secure, and evaluate the global cotton germplasm resources. Without global, collaborative efforts the rarest and most unique cotton germplasm resources are vulnerable to extinction.
