Interpretive Summary: Since the last publication of cotton pedigrees, 283 new upland and ten new pima cultivars have been released. These cultivars were released between 1995 and 2005. This compilation is beneficial to geneticists, applied cotton breeders, and policy makers since it details information needed to calculate genetic diversity, relatedness, and changes in genetic makeup found in growers fields. Gene pools and influential breeding programs can be identified. Pedigree information was obtained from various sources but primarily from the originator or breeder. If the cultivar was filed in the Plant Variety Protection (PVP) office then that becomes a source if needed. Crop Science registrations were also used. Cultivars have been listed under different names at times and we attempted to list the cultivars as listed in the PVP certificate or the Crop Science registration; however, brand names of cultivars did change for some. List of cultivars, experimental designations, PVP numbers, Crop Science registration numbers, year of release, and detailed pedigree information on the parents is given. This information will be useful in tracking how cultivars were developed.

Technical Abstract: From 1995 to 2005, 283 new upland cotton (Gossypium hirsutum L.) and 10 new Pima cotton cultivars have been released. This compilation includes the pedigrees of these as well as the 356 upland and 11 Pima cultivars previously reported. This genetic information can be used by geneticists, applied cotton breeders, and public policy makers. Contributions of various gene pools can be assessed, as well as, the contributions of various public and private breeding programs can be determined. Breeders can identify parents to use in their breeding programs. Genetic diversity and long term germplasm improvement can be examined. One can trace back the parentage of most cultivars several generations and some even to the ancestors. Relative genetic relatedness can be calculated from the pedigrees.
