Safe transfer of maize germplasm

Contributors to this page: CIMMYT, Mexico (Etienne Duveiller, Monica Mezzalama, Eloise Phipps, Thomas Payne, Jesper Norgaard), Independent consultant (Jesse Dubin). IITA, Nigeria (M. Ayodele, L. Kumar).

CIMMYT, as one of the 15 CGIAR centers, has the mandate for care and maintenance of maize germplasm. The Wellhausen-Anderson Genetic Resources Center provides secure, long-term storage for critical maize genetic resources; facilitating their use to solve practical breeding problems; improving knowledge about genetic diversity; developing and assessing complementary strategies for in situ and ex situ conservation; exploring genetic diversity at the molecular level; helping develop global databases on maize genetic resources.

The Plant Genetic Resource Center’s specially designed vaults currently hold some 22,000 samples of maize and teosinte, a wild relative of maize. The Center also maintains a living collection of Tripsacum, a more distant maize relative.

Both CIMMYT and IITA have responsibilities for maize and the information on quarantine regulations and guidelines is presented for both institutions.
