The potential economic impact of Guinea-race sorghum hybrids inMali: A comparison of research and development paradigms uri icon

abstract

  • Rural Malians depend on sorghum as a staple food. Despite long-term investment in sorghumimprovement, achieving major gains in sorghum yields has posed challenges. We assessed thepotential economic impact of the first Guinea-race sorghum hybrids developed and diffused usingparticipatory plant breeding with decentralised, farmer-based seed systems. We compared thisapproach to formal plant breeding with a centralised, state-managed seed system ? the sole approachpursued in Mali prior to 2000. To incorporate risk, we augmented the economic surplus model byapplying Monte Carlo sampling to simulate distributions of model parameters. A census of sorghumvarieties in 58 villages of the Sudanese Savanna served as the adoption baseline. Our findingsindicate that research on sorghum hybrids with the new approach is a sound investment. Public andprivate actors need to continue investing in innovative ways to expand the sorghum seed system. Thesensitivity of results to the price elasticity of supply suggests commercialisation opportunities
