Screening of Germplasm

• Kenya (KARI field site) during 2005 4000, and
  during 2006 10,000
• Ethiopia (EARO field site) during 2005 2000,
  and during 2006 2,000
• Outcome Cultivars, advanced breeding lines and
  other sources of resistance identified in
  materials provided by various countries.
