In the early years of CGN it was decided not to include the carrot collection from the Centre for Plant Breeding and Reproduction Research (CPRO) in Wageningen and to donate it to HRI (now: Warwick Genetic Resources Unit, University of Warwick) in Wellesbourne. In 1990-1992 about 530 accessions from CPRO were moved to the UK, later on followed by samples collected 1997 and 1999 in Uzbekistan and Kyrgyzstan and some landraces from different origins. At Warwick-GRU these 579 accessions are being well maintained and available for distribution.
In the framework of CGNs initiative to profile as a vegetable genebank, a carrot collection was set up in 2011, initially duplicating some wild carrot accessions from the US collection in Ames, which were not available in Europe. Furthermore some wild carrots from the Netherlands were included. However, the main part will consist of Daucus carota accessions collected in Uzbekistan and Kyrgyzstan in 2015, which will become available after the embargo period of five years has ended, following the rejuvenation by breeding companies. Currently 14 accessions are available for distribution.
Regeneration occurs in netted cages in the greenhouse with about 80 plants. Flies are included to perform the pollinations.
