The online publication "Historically Used Vegetables" provides information about 6,998 vegetable varieties, which had been described in seed catalogues, monographs, periodicals, journals, variety lists, descriptions and reports published between 1836 and 1956.
Variety descriptions, cultivation and usage indications as well as illustrations were extracted from these historical sources and are available in this online publication. Furthermore it was examined if seed samples of these varieties are currently conserved in any of the European gene banks (based on the European Search Catalogue EURISCO) or maintained on farm by one of the seed initiatives involved in the project. The identified vegetable species and varieties were divided into the following categories:
Red List: Mentioned in historical sources, not registered any more as official vegetable variety, and seeds are available in genebanks and / or from seed initiatives.
Traditional variety: Mentioned in historical sources and currently listed in the EU common catalogue of varieties. Some of these traditional varieties are listed in the EU common catalogue of varieties as a conservation or amateur variety.
Lost: Mentioned in historical sources, not registered any more as official vegetable variety, and no seed samples could be retrieved. 75% of the varieties examined in the project are considered lost.
The list of indigenous endangered and lost vegetables and traditional vegetable varieties was developed by the Department of Urban Plant Ecophysiology, Humboldt University Berlin. The development took place within the framework of the research project "Extension of the 'Red List of Endangered Local Crops’ to include vegetable varieties” and was funded by the Federal Ministry of Food and Agriculture (BMEL) through the Federal Office for Agriculture and Food (BLE) (grant number 2811HS019).
