What is safety duplication

Safety duplication helps to prevent loss due to disasters. It is used to ensure that there are multiple preservation sites for germplasm accessions conserving variability for the global user community, in perpetuity.

Safety duplication serves to:

When should it be used

Sample specifications

To conserve adequate amounts of seed in long-term seed storage.

Minimum sample size

Moisture content

Container specifications

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

Seed packaging method

Specifications of packaging material

Three-ply aluminum foil bags should be used comprising:

Storage specifications

Assigning location codes in boxes

Storage conditions

Shipping method

Should be safe, economical and fast enough to avoid delays and deterioration of seed quality during transfer.

Legal arrangements

Recording information during safety duplication

Each bag has a label containing all the necessary information about its content (photo: CIMMYT)

The following information should be recorded for each step:

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.
