Overview of research options in PGRDEU

List of crops and crop wild relatives

Which plant species are cultivated in Germany? Which wild plants are of current or potential importance for food and agriculture? PGRDEU provides the answer with the list of plant genetic resources.

Ex situ collections

In which German genebank is seed and planting material of a certain variety conserved? PGRDEU answers this question under "Ex situ collections".

In situ occurrences

Which of the native wild plants have significance for plant breeding? Where does the wild vine or wild celery grow? PGRDEU offers answers in the section "In situ occurrences".

On farm inventory

Who carries out on-farm management in Germany? Where can I find seeds or planting materials of old varieties nearby? PGRDEU helps you with this search!

Genebank material

Many old varieties are conserved in genebanks or by conservation initiatives and sometimes find their way back into wider use. Variety descriptions that reveal characteristics relevant to their reintroduction are helpful in this process.

Historial variety descriptions

Which vegetable varieties were used between 1850 and 1950? How were these varieties described? Answers can be found in the database „Historical variety descriptions“.
