Recent decades of formal crop improvement• Breeding plants that can take
advantage of fertilizer, irrigation and mechanization
• Focus on yield, uniformity in a few crops
• Increasing privatization & centralization
• Molecular technologies• Lots of other technical innovations
• Broader range of crops• Participatory approaches and
other methods innovations
CCRP niche 1: Whom do we serve?
Moremarket access
Lessmarket access
High resource
endowment
Low resource
endowment
• Equity• Food security and
poverty reduction• Environmental and
social sustainability
CCRP niche 2: What crops?
International markets
Self-provisioning
Cash crop value chains
Diverse local crops
Local markets
Mixed
• Cultural value• Nutritional outcomes
CCRP niche 3: AEI through CoP
Global
Local
SystemsComponents
Pest-resistant germplasm of crop X: genetics and
pre-breeding
Participatory selection of desirable and pest-resistant
varieties of crop X in location Y
Managing pest and other risk in location Y
Combining resistance + diversity to lower pest pressure
Pest management principles and options
GxE and beyond
• Genotype by environment interaction (GxE)
• GxE G x E x M x S • Option by context
(OxC)
Better understanding of social and biophysical heterogeneity• GIS tools and spatial
skills to support better understanding and utilization of GxE…
• Farmer typologies• Gender analysis• Markets - diversification

Hopes for the workshop
• Ideas and plans for improving breeding programs• Build skills
• For self-critique; critical friendship• For using biodiversity, METs, FRNs
• Deepen understanding and capacity for AEI-oriented PB programs • How can PB improve system performance? • Strengthen awareness of farmers’ roles and rights; breeders’
engagement strategies. Relevance of FRNs.
• Identify key policy issues affecting our work• Build cross-CCRP Plant Breeding Working Group
