  1. 1. Objective 5: Cross-crop issues Activity 1: Drought phenotyping = Refining breeder tools Proposed Workplan for Phase II ICRISAT – CIAT – ISRA – Univ North Carolina – NARS of different crops
  2. 2. Background and rationale for that activity No cross specie phenotyping in Phase I but comparative genomics Different crops work on similar traits with different methods Incomplete / unrefined breeder tool box No clear idea of trait value on yield Capacity building (human) on drought phenotyping needed
  3. 3. What traits? Reproduction / partitioning Water use / productivity Jw Water uptake
  4. 4. Proposed sub-Activities Sub-Activity 5: Training Water use / productivity Water uptake Reproduction and partitioning Modeling
  5. 5. How to improve / enlarge / refine the breeder tool box? “Breeder toolbox” SPAD / SLA CID Staygreen CTD Grain number / Grain size Relation with yield Relation with essential processes whose effects can be modeled Prediction of trait / process value on yield More / better tools
  6. 6. (Link with Trait phenotyping + phenot protocols Services of MBP) “Breeder toolbox” SPAD / SLA CID Staygreen CTD Grain number / Grain size
  7. 7. (Link with Trait phenotyping + phenot protocols Services of MBP) “Water uptake” “Water use / “Breeder toolbox” Productivity” High TE SPAD / SLA High mesophyll capacity CID Low Gs Staygreen Stomata sensitivity CTD to VPD Grain number / Pre/post -anthesis Grain size water use “Reproduction / Remobilization”
  8. 8. “Water uptake” “Water use / “Breeder toolbox” Productivity” High TE SPAD / SLA High mesophyll capacity CID Low Gs Staygreen Stomata sensitivity CTD to VPD Grain number / Pre/post -anthesis Grain size water use “Reproduction / Remobilization”
  9. 9. “Water uptake” “Water use / “Breeder toolbox” Productivity” High TE SPAD / SLA “Right” kinetics of High mesophyll capacity water uptake CID Low Gs Staygreen Higher water Stomata sensitivity uptake CTD to VPD Grain number / Pre/post -anthesis Grain size water use “Reproduction / Remobilization”
  10. 10. “Water uptake” “Water use / “Breeder toolbox” Productivity” High TE SPAD / SLA “Right” kinetics of High mesophyll capacity water uptake CID Low Gs Staygreen Higher water Stomata sensitivity uptake CTD to VPD Grain number / Pre/post -anthesis Grain size water use Flower “tolerance” Shorter/longer flower PPI / PHI to water stress to maturity interval SBR / HI “Reproduction / Remobilization”
  11. 11. “Water uptake” “Water use / “Breeder toolbox” Productivity” “Right” kinetics of water uptake ? ? Low Gs Staygreen Higher water ? ? Stomata sensitivity uptake to VPD ? Pre/post -anthesis water use
  12. 12. Does my tool relate to yield?
  13. 13. How does the tool relate to a process?
  14. 14. “Water uptake” “Breeder toolbox” “Right” kinetics of water uptake Staygreen
  15. 15. Testing traits by Crop simulation modeling “Water uptake” “Breeder toolbox” “Right” kinetics of water uptake Staygreen
  16. 16. Probability of yield increase – Trait A 75% Median 25%
  17. 17. Probability of yield increase – Trait B 75% Median 25%
  18. 18. Testing traits by Crop simulation modeling “Breeder toolbox” Trait A Trait B
  19. 19. Testing traits by Crop simulation modeling “Water uptake” “Water use / “Breeder toolbox” Productivity” High TE SPAD / SLA “Right” kinetics of High mesophyll capacity water uptake CID Low Gs Staygreen Higher water Stomata sensitivity uptake CTD to VPD Grain number / Pre/post -anthesis Grain size water use Flower “tolerance” Shorter/longer flower PPI / PHI to water stress to maturity interval SBR / HI “Reproduction / Remobilization”
  20. 20. Outputs to TLII Sub-Activity 5: Training Water use / productivity Water uptake Reproduction and partitioning Modeling Trait value Refined protocols Better pheno- predicted More tools typing data
