Inventory and history of the CIRAD cotton (Gossypium spp.) germplasm collection
2006
Dessauw, D. | Hau, B.
The CIRAD Cotton Germplasm Collection was founded in 1978 through the pooling of a number of working collections. It is one of the largest collections in the world representing genetic variability in the genus Gossypium L. In 2005, it contained 3070 accessions, including 1696 cultivars and 1374 wild and ancestral types, covering five tetraploid species and seven diploid species. The two main cultivated cotton species, G. hirsutum L. and G. barbadense L., accounted for 68% and 15% of the accessions, respectively. The cultivars originated from around a hundred countries, and the ancestral species accessions were collected during expeditions conducted between 1980 and 1988. Part of the ancestral type collection (894 accessions) was assembled with funding from IBPGR (now Bioversity International), and these accessions were handed over to CIRAD for conservation, assessment and release.
