A user-friendly tool to estimate the requirements for Early Generation Sweetpotato Seed (EGS) is now available for use by public sector seed producers. The method was first used in Uganda to estimate the seed requirement by root producers for quality seed of improved varieties; then estimates of the number of basic seed multipliers this will require; and finally, the amount of pre-basic cuttings and tissue culture plantlets to be produced. Results indicate a need to treble the existing pre-basic seed production capacity; decentralize pre-basic screenhouse capacity to get broader national coverage; improve screenhouse design and utilization to increase efficiency and reduce the cost of pre-basic seed production. Scaling EGS production and linkages through the chain will only be successful if there is an expansion in the root markets driving demand for quality seed.
