[Day 3] Agcommons Quickwin: African Trial Sites

  1. 1. Trial Sites  Cultivar testing is a key element in the process of delivering varieties to farmers  Multi Environment Trials (MET) and GxE analysis have a rich history going back 100+ years  Trial networks for the cereal crops have been especially effective in the past
  2. 2. Trends in MET’s  RENACO [West and Central African Cowpea Research Network], disappeared about 10 years ago when USAID money stopped flowing  IBYAN (International Bean Yield Assessment Network) ended in 1996 for lack of funds  In the 70’s germplasm was novel, more material out there today  Greater quarantine restriction today  Growth of profit-oriented research groups, especially in Asia and LAC  weakening of NARS and IARCs?
  3. 3. “The poor performance of public institutions in disseminating improved varieties to small-scale farmers is broadly accepted, and there is an urgent need to design and test new institutional arrangements …..” World Bank Development Report 2007
  4. 4. Changes since heyday of MET’s  Changes in computing mean better data management today  Computational Biology: Advances in bioinformatics can link site phenotyping to molecular breeding platforms  Computational Geography: Geographic information science and technology  The Internet  Web 2.0
  5. 5. Proposed Pilot Project: Africa Trial Sites Catalogue - Reaching out to farmers, agronomists and plant breeders with spatially efficient, participatory testing networks A catalogue of trial sites, managed and maintained by network community: Melkassa, Ethiopia site
