For information on prices and conditions: List of Services (MATREF services can be found under "Disease testing material").

For other services from the GEVES Pathology Laboratory, please refer to the following sections:

• Disease testing for external clients
• Pathogen detection

• Provide reliable and available reference material for disease resistance tests, including:
  • Controls: susceptible, intermediate, resistant cultivars
  • Differential hosts: for identification of races, e.g. the differential set for Bremia lactucae, in collaboration with the IBEB.
  • Pests and pathogen isolates
• Harmonise reference material (controls, differential hosts, pathogens and pests) between official laboratories and seed companies in order to optimise the consistency of results for resistance assessment when GEVES and INRA check the resistance claims of seed companies.
• Share tasks and costs between network members for validation, maintenance, and distribution of seeds and pathogen strains.

MATREF provides a collection of reference material, managed by database:

Seed material

• Validated as controls in official tests following confirmation of resistance/susceptibility behaviour
• Validated as differential hosts using reference strains
• Tested for germinative capacity by GEVES or seed companies from the network
• Seed health testing: tests for main seed diseases in the European Union
• Stored in an active bank at 4°C and backup bank at -18°C

Pathogen strains

• Controls and differentials validated for aggressiveness and virulence
• Maintained by the official laboratory (GEVES or INRA) or an active bank and stored as a long term back up in 2 secure locations

Distribution of seeds and strains is managed by GEVES. This distribution is free for members of the MATREF network. Control and differential seeds and pathogen strains are also available for non-members; for non-members there is a fee and seed quantity is restricted. Please see the GEVES List of Services for more information.
