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 principles – how do they apply to crop improvement projects?

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
