The research programs of Pro-Maïs are long term programs concerning :
- characterization and preservation of genetic resources
- history of maize biodiversity in the world
- development of new breeding methods
- genetics of maize and its prgenitor teosinte
- domestication and adaptation to Europe
- digestibility of fodder maize
- drought tolerance
These programs are co-financed by the partner breeders on the basis of volunteering.
They are realized in collaboration with INRA stations and laboratories : Montpellier, Le Moulon (UMR de génétique végétale), St Martin de Hinx, Lusignan, IJPB Versailles, Estrée Mons.
