Research will be implemented within 5 components, each focusing on delivering technological, marketing, and institutional innovations that will contribute to the following primary outcomes:

• Yam Component: Yam seed system actors in Nigeria and Ghana adopt innovations that result in more efficient and economically viable high-quality seed delivery of market-preferred varieties to smallholder farmers by 2027.
• Banana Component: Economically viable banana seed systems are established by seed system actors in Ghana, Nigeria, Rwanda, Tanzania, and Uganda through the application of novel or improved innovations to tissue culture, macro propagation and nursery enterprises that deliver market-preferred varieties to farmers by 2027.
• Sweetpotato Component: Sweetpotato seed system performance is improved through technological, marketing, and institutional innovations that deliver timely, affordable quality seed of market-preferred varieties to actors in the Eastern Region of Uganda and the Lake Zone of Tanzania by 2027.
• Cassava Component: Cassava seed system actors in Nigeria, Tanzania and Rwanda adopt innovations that increase the cost efficiency, volume and seed quality of improved varieties delivered to smallholder farmers by 2027.
• Cross-cutting Component: Seed system actors in Nigeria, Tanzania, and Uganda validate common approaches to technological, marketing, and institutional innovations for vegetatively propagated crop seed systems that provide models for wider scaling for VPC seed delivery across Africa by 2027.
