When should it be used

See also the general page on safety duplication procedures, as well the procedures on the safe transfer of clonal germplasm that should be carefully followed.

Cassava germplasm should be duplicated in a systematic way, consistently sharing information and germplasm to optimize the conservation system.

Material should be duplicated in more than one location and/or using more than one method (i.e. in the field and in vitro or tissue culture and cryo).

Sample specifications

Container specifications

To ensure explant viability in the genebank and en route to the users.

Storage specifications

Storage conditions

Shipping method

Legal arrangements

The source centre, host country and importing centre and country policies and practices for germplasm movement for black-box storage must be fulfilled. The documentation listed below should be included to facilitate customs clearance:

IITA, Nigeria has the following procedure:

CIAT, Colombia follows these procedures:

Recording information during safety duplication

The following steps should be taken regularly, due to the short-term duration of conserving clonal crops:

The following information should be kept updated:

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.
