Genetic Resources at (WARDA) Africa Rice Center


3 pillars of our genetic resources activities

    • Germplasm collection
    • Genetic resources conservation & management
    • Genetic resources utilisation


G.R. Collection

Germplasm collection

•  Started in mid 1960's in west Africa


•  1964-1990: Bénin, Burkina , Cameroon , Chad , Cote-d'Ivoire, Gambia , Ghana , Guinea-Bissau , Liberia , Mali , Nigeria , Senegal , Sierra-Leone and Togo .

•  2000: WARDA

•  Germplasm collected : Oryza glaberrima

Oryza sativa

Oryza longistaminata

Oryza barthii

Oryza stapfii

G. R conservation & management

Ex-situ & In-situ conservation

•  Long & Medium -term storage

•  Germplasm characterisation/Evaluation

•  Gene bank management

•  Documentation and publication

•  Biodiversity and indigenous knowledge

•  Capacity building of NARS

•  Regional and international collaboration

Genetic resources utilisation

•  Increasing diversity through pre-breeding

•  Germplasm exchange and utilization through Networks

Research Challenge 1.1

•  How best should existing genetic resources be used to develop rice varieties that best fit or better optimize farmers' existing production systems and are acceptable to both producers and consumers?

  •  Breeding activities to develop new genetic material will be supported by continued investment in capacity and facilities for the conservation and management of genetic resources


Promoting ex situ conservation and use of GR

Research to understand diversity

o Full Characterization (morph. Molecular)

o Full Evaluation (genetic value)

o Genetic diversity studies

o G x E studies (INGER-Africa)

Seed technology /physiology Research to improve conservation and management

o Seed dormancy,

o Seed production environment,

o Seed drying

o Optimum seed storage conditions


Promoting in situ conservation and use

Research to understand

Farmers' knowledge

Biodiversity and environment management

o Impact of modern varieties on biodiversity

o Within and between population variability

o Population evolution, structure

o Genetic erosion

o Species distribution

o Socio-economic determinants.

GIS applications

o Turn genebank data into knowledge

o A nalyze the distribution of species as a tool to determine geographic, ecological and/or genetic patterns.

o Enhance data quality of accessions by providing or verifying locational data (geo- referencing) of collection sites.

o Effective use of germplasm in designing a crop improvement program

How to make GRU activities more visible?
