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?
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.
