GRM 2013: CGIAR Research Program on Roots, Tubers and Bananas – M Gedil

  1. 1. CGIAR Research Program on Roots, Tubers and Bananas: Overview GCP-GRM 27 September, 2013
  2. 2. A collaboration of: + a wide spectrum research-for-development stakeholders & partners
  3. 3. Banana Plantain Cassava Potato Sweetpotato Yam Other R&T Our crops 200 million farmers depend on RTB crops Buffering role in food systems

  6. 6. • Increased scale • Critical mass of researchers • Greater capacity • Exploit synergies: genuine “win-wins” eg similarities in seed systems and post harvest management To do together what we cannot do separately Program “value added”
  7. 7. RTBs share • Genetic complexity • Lengthy growing season • Vegetative propagation, similar seed systems • Low multiplication ratio • Disease build up • Unrealized high yield potential • Under-investment • Inadequate research and poor dissemination of technological innovations Why Roots, Tubers and Bananas?
  8. 8. Why Roots, Tubers and Bananas?  Bulkiness:  implications for handling, transport, storage, crop hygiene: farm gate processing, proximity to industries  Perishability implications for marketing, utilization, crop management  Insufficient and poor quality planting material  Limited use of improved post harvest handling technologies
  9. 9. Genetic Improvement Challenges 1 Genetics poorly understood 2 Long Breeding cycle* except Potato 3 Flowering/incompatibility 4 High level of heterozygosity 5 Limited Genomic resources 6 Critical mass of researchers 7 High GXE 8 Low Genetic Diversity 9 High post-harvest losses 10 Low multiplacation ratio 11 No private sector interest
  10. 10. Program structure: Integrates 7 Themes Theme 1 Conserving and accessing genetic resources Theme 2 Accelerating the development and selection of varieties with higher, more stable yield and added value Theme 3 Managing priority pests and diseases Theme 4 Making available low-cost, high-quality planting material for farmers Theme 5 Developing tools for more productive, ecologically robust cropping systems Theme 6 Promoting postharvest technologies, value chains, and market opportunities Theme 7 Enhancing impact through partnerships
  11. 11. Theme 1 and 2: Germplasm enhancement Theme 1 Conserving and accessing genetic resources Theme 2 Accelerating the development and selection of varieties with higher, more stable yield and added value Research Outcomes: • Increased Access to, and enhanced use of RTB genetic resources • Increased NARS capacity in breeding, pest and disease mangt, quality seed systems. • Accelerated development of RTB varieties with pro-poor traits by NARs
  12. 12. Novel Component by Theme
  13. 13. Theme 1 Impact Pathway: product lines, products, outcomes, and impacts
  14. 14. Theme 2 Impact Pathway: product lines, products, outcomes, and impacts
  15. 15. PL 1: Breeding tools, strategies, and approaches • Screening tools for nutritional quality: NIRS • Improved flowering of parental lines: phytohormones, flowering genes • Heterosis breeding: heterotic patterns • Inbreeding for RTB improvement: e.g. unravel recessive alleles; reduce genetic load • Accelerated selection schemes and MAS
  16. 16. Biotechnology Tools • Marker-assisted selection • Association mapping • Genomic Selection • Genetic modification • Mutation induction enhanced breeding • Unraveling host-pathogen interaction
  17. 17. PL 2: Trait capture and gene discovery Phenotyping—a crucial and challenging issue • Rapid, accurate, large‐scale phenotyping • Plant architecture – non destructive MRI (CIP-Embrapa) • Drought and heat tolerance • “virtual phenotyping platform.” • Gene Discovery: TILLLing ecoTILLing • Pre-breeding: AB-QTL (introgression); ploidy induction; DH
  18. 18. Complementary projects: capture “value added” Theme Theme name Title Type 1&2 Genetic resources Enhancing Global RTB Productivity through more targeted use of global genetic diversity; Full proposal 2 Development and selection of varieties Multi-centre planning on Banana/Plantain Improvement Planning grant 3 Managing priority pests and diseases Developing tools for describing, quantifying and managing diseases causing degeneration of planting material in RTB Full proposal 3 Managing priority pests and diseases Towards the development of comprehensive strategy for combating Bemisia tabaci – a continuing menace to R&T crops Planning grant 3 Managing priority pests and diseases Building a collaborative, public-private R4D alliance to address BBTV in Sub-Saharan Africa; Planning grant 3 Managing priority pests and diseases Management of critical pests and diseases of RTBs through enhanced risk assessment and surveillance Planning grant 4 Seed systems Developing a proposal for modelling RTB-seed systems: Towards decision support systems for improving seed related investments Planning grant 5 Robust cropping systems Identifying and quantifying yield gaps in RTB crops to devise technologies for increased RTB production Planning grant 7 Impact through partnerships Reaching end user through capacity strengthening and learning: A needs assessment Planning grant 7 Impact through partnerships From rhetoric to reality on gender: Implementing the RTB gender strategy Planning grant 7 Impact through partnerships Partnerships and knowledge sharing for innovation in roots, tubers and banana research for development Planning grant
