Plant Breeding Pipelines in the CCRP

Historical reflections importance from the start of CCRP1

Recent decades of formal crop improvementBreeding plants that can take advantage of fertilizer, irrigation and mechanization Focus on yield, uniformity in a few crops

Increasing privatization & centralization Molecular technologiesLots of other technical innovations

Broader range of cropsParticipatory approaches and other methods innovations

CCRP principles how do they apply to crop improvement projects?

CCRP niche 1: Whom do we serve?Moremarket accessLessmarket accessHigh resource endowmentLow resource endowmentEquityFood security and poverty reductionEnvironmental and social sustainability CCRP niche 2: What crops?International marketsSelf-provisioningCash crop value chainsDiverse local cropsLocal marketsMixedCultural valueNutritional outcomes CCRP niche 3: AEI through CoPGlobalLocalSystemsComponentsPest-resistant germplasm of crop X: genetics and pre-breedingParticipatory selection of desirable and pest-resistant varieties of crop X in location YManaging pest and other risk in location Y
