The European Central Trifolium repens database is maintained by the Genetic Resources Unit at IGER. The Trifolium repens database is both available as a downloadable spreadsheet and searchable on-line at the Internet server of IGER. It contains passport data on 1350 accessions of Trifolium repens stored in 14 European genebanks. The collections contain accessions from 33 countries or regions, 2 of them outside Europe, and include advanced cultivars (533), primitive cultivars (12), wild or semi-wild material (450), breeding or research material (51), botanic garden samples (6) and material of unknown type (298). Seed requests should be sent directly to the holding institutes.
