  • Nice to see climate change adaptation research work particularly for crops like Barely,now I am also working on such area and have keen to meet you all the biodiversity experts

  • 1. Alganesh T.,Mehamed Ehsan.D,Kassahun E., Basazin F.,Tesfaye W.S.,Marteen, Imke, Tesema T. and Wilson M.Institute ofBiodiversity Conservation
  • 2. Synopsis•Introduction•Objectives•Methodology•Results•Recommendations
  • 3. IntroductionThe effect of physical feature of EthiopiaChallengesOptions
  • 4. The possible explanations Physical feature of the country
  • 5. Chain mountains 4620 m.a.s.l 120 m.b.s.l
  • 6. • Great Rift Valley ¨µ‹“ c”cKT }^a‹Great Rift Valley
  • 7. Rivers and lakes
  • 8. Arabian seaIndian oceanAtlantic ocean
  • 9. All this situation makes the countryto have diversified ecological zone 862/16

  • 14. oClimate change
  • 15. What we have done ? oEx-situ conservation 60,000 acc. orthodocs seeds 10,000acc. recalsitrant oil crops pulses 7,000 8,000 12% 13% cereals 45,000 75%
  • 16. 39% Other cereals61% Wheat & Barley 26,000 accession of W&B stored
  • 17. Whats not? oIn - Situ Conservation????? oInventory??????????????? 12 community gene banks
  • 18. •Taxonomic classificationWheatFamily :PoaceaeGenus :TriticumOrigin and Domestication o Fertile crescent, domesticated 10,000 years ago BarleyFamily :PoaceaeGenus :Hordeum
  • 19. ObjectivesoTo identify promising adaptive variantsoEvaluate and characterize prommising accessions from gene banks with the participation of women farmersoTo make available & provide access to better-suited crop varieties for targeted local communities to use in adapting to climate change.
  • 20. Materials and MethodsoGenetic materials – 100 Acc of Wheat & 100 Acc of barley (Koka, Ejerie, & Cheffe- 1400,2200 &2450Evaluatorso140 W and 10 couples were selectedoExploited 19 traits for wheat & 16 traits for barley.
  • 21. No of variants found per crop 60No of variants 40 41 55 20 0 Wheat Barley Crop type
  • 22. 41 variants found per2000genotypes of wheat in Koka 10 v excellent performance 17v intermidate EP ISH OT 14v off type

  • 24. ResearchersFarmers selection selection 8v 7v 8V 23v Common variant
  • 25. Comparison made among sitesKoka site Ejerie site 8v 2v 13V 2v
  • 26. How selection criteria affects diversity ? 33v
  • 27. o Math logic :1X + 1X = 2X ,o Diversity logic : 1X + 1X = only 1Xo………………...: 1X + 1Y = 3 = X,xy,YoTherefore ,we have to look always for the unique character
  • 28. Awn roughness farmers preference 15 v RA in Ejerie 16 vsmooth in cheffe 15 vrough in koka
  • 29. Improved varietyLand race
  • 30. Some variants susceptible to head smut
  • 31. Ethiopian seed Custodian
  • 32. Cause & effect of genetic erosion Ik not documented
  • 33. RecommendationsFarmers are a source of valuable information and knowledge. Therefore, it should be documented protected and broad cast their vital indigenous knowledgeWithout a diverse genetic reservoir to draw for further improvement may not be possible, therefore it should be conserve our genetic reservoir.It would be better to encourage farmers to continue to manage a landrace gene pool in evolutionary real time
  • 34. IK Conservatio n Research
  • 35. Relax but respect the ecosystem Thank you
