This manual describes the yam in vitro genebanking process set up by IITA.

Within the last 3 years, this process has been successfully used to duplicate over 1000 accessions of yam from field to in vitro culture. Research is still going on to optimise yam in vitro genebanking, especially at meristeming level. The manual also describes minimum requirements in terms of equipment and consumables for yam in vitro propagation and genebanking.

Compilation by: Dominique Dumet, Abigael Adeyemi, and Omena Ojuederie

Intended use:

Best practice reference manual for genebank staff.
Provide the frame for further development of ISO normalization (quality control of in vitro germplasm) for yam gene banking.
Support capacity building in in vitro culture and gene banking. This manual is accessible on the IITA website and available in hard copy (upon request).

Intended users: Genebank managers, supervisors, and staff and trainees
