  2. 2. WHAT DO WE WANT TO BREED FOR?  High Grain & StrawYield  Quality Grain and Straw  Climate Friendly/Resilient Grain and StrawYield Resistance 2 Biotic Factors Resistance toAbiotic Factors  Erect, Non-lodging Plants Conventional Breeding Non-conventional Breeding 1. Mutation Breeding 2. Intra-species Breeding 3. Biotechnology
  3. 3. WHERE DO WE START?  Very HighVariability inTef Germplasm  KnowledgeThatTef Is A C-4 Plant  Already Established Cross-breeding Technique  Already Established GoodVarieties  Signs that Mutation Breeding Can Contribute  Successful Breeding Results In Other Cereals  Wheat  Rice  Etc
  4. 4. IN THE NATIONAL TEF STRATEGY  BREEDING CHALLENGES  Insufficient priority is given to tef research, resulting in limited institutional and resource capacity  Limited basic research on tef exists to serve as a basis for further exploration  Limited basic research on tef exists to serve as a basis for further exploration  Genetic resource collection and management is insufficient  Tef varieties released so far do not adequately address lodging, biotic/abiotic stress, shattering, food products, etc.  Limited applied research in many areas such as socioeconomics, soil, physiology, food chemistry, crop protection and mechanization  PROPOSED INTERVENTIONS  Enhance institutional system and capacity in financial, human and material capital  Strengthen basic research (physiology, genetics, cytogenetics and genomics) on tef  Strengthen basic research (physiology, genetics, cytogenetics and genomics) on tef  Develop comprehensive genetic resources collection and characterization  Strengthen and accelerate varietal development through breeding /Biotechnology  Enhance applied research in areas such as socioeconomics, soil, physiology, food chemistry, crop protection and mechanization  Strengthen research related to other value chain steps
