The crucifer collection exists of more than 40 crop groups. For the major part, 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.
The CGN collection of cruciferous crops includes 1750 accessions. The collection contains cultivars (N=1080), landraces (N=294) and research material (N=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, B. napus, B. carinata and Raphanus sativus. 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). CGN developed the European Brassica Database: ecpgr.cgn.wur.nl/Brasedb/ (Bras-EDB) in the framework of the Brassica Working Group of the European Cooperative Programme for Crop Genetic Resources Networks (ECPGR, Maggioni et al. 1997). The ECPGR Brassica database contains passport data of most of the European Brassica collections.(Van Hintum and Boukema 1993, Boukema and Van Hintum1998, Bas and Menting 2009). As EURISCO (eurisco.ipk-gatersleben.de) is now functioning as the European database of PGR, the Bras-EDB has not been updated and is not on-line searchable since 2019. All data are still downloadable.
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.
