PGRDEU does not only provide inventories of plant genetic resources conserved ex situ-, in situ- and on-farm, but also thematic lists on plant genetic resources. The following thematic lists are currently available: List of plant genetic resources in Germany, the Red List of endangered local crops in Germany, and the List of historically used vegetables.
The German PGR list is a comprehensive list of plant taxa (including intraspecific taxa) occurring in Germany with actual or potential value for food, agriculture, horticulture and foresty. The list was compiled within the framework of the national program and contains 3,600 cultivated and wild taxa. It provides use categories for all taxa, where the categories “ornamental” and “breeding” have not been completed yet.
The crop diversity used in agriculture, horticulture, viticulture, and orchards has been declining over the past century not only in Germany but globally. Today, only a small number of crops is economically important and the varietal diversity within crops is often decreasing too.
To draw attention to this situation in Germany and to support measures aimed at conserving and sustainably using plant genetic resources, the Red List of Germany’s endangered local crops was produced. It encompasses all groups of local crops and their varieties, which had had regional significance and had been adapted to local conditions in Germany.
List of indigenous endangered and lost vegetables and traditional vegetable varieties
For the first time in Germany, scientific research was carried out to record the varietal diversity in vegetable crops available between 1836 and 1956 and investigate whether seeds or planting material of these varieties is still available today. The research identified about 7000 old vegetable varieties and species. 75% of this diversity had to be classified as lost, as no seed or planting material could be retrieved any more. The research results are published in the database "Historically Used Vegetables", which also includes about 3000 illustrations.
