Common databases

Portals that collect Plant Genetic Resources information from different sources are a great place to start searching for material.

EURISCO

EURISCO is regularly updated and contains the data of European collections. It also contains phenotypic data for lettuce for various traits (over 100.000 data points). EURISCO does not provide contact information for seed requests. Germplasm availability is not a criterion for uptake in this database.

Genesys

Genesys is a global portal to information about Plant Genetic Resources. It contains almost 4.5 million accessions, with more than 15,000 Lactuca accessions. The European PGR-data are regularly imported from EURISCO into Genesys.

International Lactuca database (ILDB)

The ILDB is not limited to European collections. It contains phenotypic data of the project 'Leafy vegetables germplasm, stimulating use', while it also provides contact details of the collection holders. Although ILDB accessions are supposed to be available upon request, this cannot be guaranteed as this depends on the reliability of the provided information. The ILDB is not updated anymore. The last update was in 2010.
