Product development of genetically modified NERICA

  1. 1. Product Development of Genetically Modified NERICA- 4 with Nitrogen-use Efficiency, Water-use Efficiency and Salttolerance traits for Deployment to Farmers in Sub-Saharan Africa P. Addae, J. Mignouna, J.van Boxtel, K. Dartey, J. Lamo, M. Obokoh, M. Tswako Third Africa Rice Congress, Yaoundé, Cameroun 21-25 October, 2013
  2. 2. Constraint to Rice farming: Nitrogen deficiency
  3. 3. Constraint to rice farming: Drought
  4. 4. Constraint to rice farming: Salinity
  5. 5. Mitigations to these constraints • Conventional Breeding - Developing tolerant varieties • Plant Biotechnology - Introducing novel genes into plants to develop tolerant varieties • Role of African Agricultural Technology Foundation (AATF)
  6. 6. Role of AATF • Not for profit organization based in Kenya - Accesses proprietary and non-proprietary agricultural technologies on royalty- free basis - Forms partnerships with public & private institutions globally to develop the technology - Develop the technology with partners - Deploy the technology to small-holder farmers in Sub –Saharan Africa (SSA)
  7. 7. NEWEST RICE PROJECT • Technology Provider: Arcadia Biosciences, USA • Nitrogen Use Efficiency (NUE) - source: Barley • Water-use Efficiency (WUE) - source: Bacteria protein • Salt –tolerance (ST) - source: Rice • Transformation variety: NERICA-4
  8. 8. NEWEST RICE PROJECT Product Development - Efficacy testing of transgenic lines in confined field trials (CFT) - Locations (2): Ghana & Uganda - 8 NUE lines, 8 Isogenic lines and NERICA-4 (control) - Fertilizer rates: 30, 60, 90 Kg N/ha - Two plantings to be done in 2013 - Data collection in progress - NEWEST lines to be planted in 2014
  9. 9. NEWEST RICE PROJECT NUE lines planted with 3 different fertilizer rates of 30, 60 & 90 kg N/ha in Ghana
  10. 10. Acknowledgements • USAID –funding • Arcadia Biosciences – Technology provider • National Agricultural Research Systems (NARS) - conduct CFTs - Crop Research Institute, Ghana - National Agricultural Research Institute, Uganda - National Cereals Research Institute, Nigeria • CIAT - produces transgenic seed for testing
  11. 11. P. Addae - Africa Agricultural Technology Foundation (AATF), Kenya J. Mignouna - Bill & Melinda Gates Foundation (formerly with AATF) USA J.van Boxtel- Arcadia Biosciences, USA K. Dartey - CSIR-Crops Research Institute, Ghana J. Lamo - National Agricultural Research Organization (NARO), Uganda A. Maji - National Cereals Research Institute (NCRI), Nigeria, M. Obokoh - AfricaBio
  12. 12. Constraints on Rice farming • Nitrogen deficiency - Prohibitive fertilizer costs - Unavailable - Losses from the soil • Drought - Climate change - Unpredictable weather patterns - Recurrent • Salinity occurs in coastal & irrigated soils
