The crucifer collection exists of more than 40 crop groups. The collection originates from the former Foundation for Plant Breeding (SVP), the Institute for Horticultural Plant Breeding (IVT) and departments of Wageningen Agricultural University (WAU, now part of Wageningen University and Research Centre).
Part of the material was collected in the Netherlands in the framework of the EU project "The collection of landraces of Cruciferous crops in the EC countries" (van der Meer et al. 1984).
Presently, the CGN collection of cruciferous crops includes 1750 accessions. The collection contains mainly cultivars (1080), furthermore landraces (294) and research material (181). Only 14 accessions are documented as wild populations and of 181 accessions the population type is not known. B. oleracea is represented with the highest number of accessions followed by B. rapa, Raphanus sativus, B. napus and B. carinata.
CGN developed the European Brassica Database (Bras-EDB) in the framework of the Brassica Working Group of the European Cooperative Programme for Crop Genetic Resources Networks (ECP/GR, Maggioni et al. 1997). The ECPGR Brassica database contains passport data of most of the European Brassica collections and is updated regularly. (van Hintum & Boukema, 1993, Boukema & van Hintum, 1998, Bas, 2009)..
CGN coordinated a European project on Brassica: "Brassica Collections for Broadening Agricultural Use" including "Characterising and utilising genetic variation in Brassica carinata for its exploitation as an oilseed crop" (RESGEN CT 99 109-112). This project deals with characterisation, evaluation, regeneration and documentation of B. napus, B. oleracea, B. rapa and B. carinata. Results of this project are downloadable via the BrasEDB website.
