This manual might be interesting or useful for readers to see how operations at the genebank of the International Maize and Wheat Improvement Center (CIMMYT) are conducted.

In 2004, CIMMYT restructured its research programs into six new global and ecoregional programs. One of these, the Genetic Resources Program, is now home to CIMMYT’s maize and wheat germplasm banks. This new organizational structure indicates the high importance and visibility that CIMMYT places on our role as custodians of maize, wheat, and related species genetic resources.

One of the first priorities of the program was to update the operations manual for the germplasm banks. The result of this effort is this publication, the Wellhausen-Anderson Genetic Resources Center Operations Manual. The policies and procedures outlined in the manual represent those currently being used in the introduction, evaluation, maintenance, regeneration, and distribution of genetic resources at CIMMYT. By following these procedures, CIMMYT ensures that the genetic resources entrusted to it in its germplasm banks are available to the world and that they maintain their genetic integrity while under CIMMYT’s custodianship.

The Genebanks

The 11 CGIAR genebanks currently conserve 730,000 of cereals and grain legumes, forage crops, tree species, root and tuber crops, bananas and crop wild relatives.
