Jorge Andrade-Piedra RTB - Annual Meeting
Dec 8th, 2015
Theme 4: Overview – Making available low-cost, high quality planting material for farmers
Theme 4 - Background
• Planting material (seed) of RTB crops is problematic because: – Accumulation of diseases leading to degeneration – Low multiplication rates – Perishable, bulky and expensive
• Local farmer-based seed systems provide more than 95% of the planting materials
• Challenges related to planting material of RTB: – Improve quality and access – Improve dissemination of new varieties
• Long history of interventions, but poor learning from past experiences and lack of conceptual direction
Main progress 2015
• Case studies and framework • Strategy documents • Resistant varieties to combat Moko disease of plantains
in Latin America • Knowledge exchange for multiplication techniques • Impact Network Analysis • New project in Nigeria

In collaboration with Theme 3:
Strategy documents: Potato
Strategy documents: Sweetpotato
VISION: In ten years CIP envisages efficient sweetpotato seed systems which respond to male and female farmers’ demand for access to an adequate supply of quality planting material of preferred and adapted varieties when and where needed. Once accessed, farmers will be able to manage the health status of their planting material by integrating on-farm management tools with strategic seed replacement. These seed systems will be linked to root production for different markets. We recognize that there are diverse agro-ecological and socio-economic contexts where sweetpotato is an important and expanding crop. Therefore, appropriate technologies and pluralistic approaches will serve different, but sometimes overlapping and competing objectives for seed systems. These include: farmers as seed managers, national economic development, fostering entrepreneurship, nutrition well-being; and disaster risk reduction. Different elements of the formal (public and commercial), informal (farmer based) and semi-formal (NGO supported) sweetpotato seed systems, will be integrated depending on context. Synergies will be leveraged with the seed systems for other clonal crops. In the CIP vision, there is no ‘one-size fits all’ solution.
Through RTB, CIAT is collaborating with Bioversity and IITA on introducing hybrids and evaluating them for their agronomic performance; resistance to
diseases, including Moko and Sigatoka diseases; and acceptability to farmers for consumption or agroindustry in Colombia.

Building an Economically Sustainable, Integrated Seed System for Cassava in Nigeria (CBSD and CMD)
S. Walsh
• Proposal for BMGF ($11.6M, 4 years) • RTB as convening platform to formulate and manage the project • Contribution from experts in other RTB crops • Multi-stakeholder approach for designing the project (framework) • On-farm seed management approach not approved by the donor, heavy
reliance on resistant cultivars and clean seed produced off-farm.
Perspectives
• In RTB’s new structure, Theme 4 will be integrated in: • Flagship 2: Varieties and Seed • Cluster LS4: Improving smallholder access to healthy RTB planting
material and new varieties
• LS4 is expected to provide an space for collective learning and reflection. The biophysical and socio-economic perspective are being merged into a single complementary project, so to have a more holistic and integrated approach for improving RTB seed systems.
• Several challenges on the managerial side that should be taken into account:
• The idea of sharing information across regions is exciting, but in practice it is complex and expensive
• Also, the idea of piggybacking into existing projects need to be refined.
• RTB’s seed systems share the same challenges and opportunities, so integration around this subject occurs “naturally”, and our community of practice is active.
