  1. 1. Working together with the Queensland Government Developing drought-adapted sorghum germplasm for Africa and Australia University of Queensland Andrew Borrell & David Jordan Queensland Government B. George-Jaeggli & Simon Hamlet IER, Mali Sidi Coulibaly & Niaba Teme INERA, Burkina Faso Clarisse Barro-Kondombo ARC, Sudan Abdalla Mohamad INRAN, Niger Soumana Souley EIAR, Ethiopia Alemu Tirfessa & Asfaw Adugna KARI, Kenya Clement Kamau
  2. 2. Working together with the Queensland Government Outline 1. Introduction 2. Highlights from the past year 3. Tangible products created by our project 4. Anticipated impact of products on downstream beneficiaries 5. How they will these products be maintained and sustained? 6. Conclusions
  3. 3. Working together with the Queensland Government Crop productivity in water-limited environments is regulated by: Drought adaptation in cereals The ‘stay-green’ trait affects all three processes. a) the extent of water capture by the crop (T), b) the efficiency with which the crop exchanges water for CO2 via transpiration in producing biomass (TE), and c) the fraction of the total biomass that ends up in the grain (HI).
  4. 4. Working together with the Queensland Government What is stay-green and why is it important? There is a high frequency of post-flowering drought in cereal-growing areas world-wide, including north-eastern Australia, central-western India, southern USA and sub-Saharan Africa. Delayed foliar senescence, known as stay-green, is a drought adaptation trait that enhances crop productivity in the field when water is limiting after flowering.
  5. 5. Working together with the Queensland Government Higher yield Increased water use during grain filling Increased water availability at flowering Increased water accessibility (roots) Reduced water use at flowering Higher plant water status Increased growth rate Increased TE Delayed leaf senescence Smaller plant size ‘Low tillering’ mechanism ‘Small leaf’ mechanism Modified leaf anatomy Driving T Driving TE Driving HI Emergent consequences Increased N uptake Increased stem strength
  6. 6. Working together with the Queensland Government Our project aims to a) develop drought-adapted sorghum germplasm for Africa and Australia, and b) provide training in crop improvement for scientists in Africa. Over the past year, our project has expanded to six African countries. Highlights from the past year
  7. 7. Working together with the Queensland Government African partners (Phase 2)
  8. 8. Working together with the Queensland Government Highlights from the past year: Germplasm development Stay-green enriched germplasm is currently being evaluated in six African countries (Mali, Burkina Faso, Niger, Sudan, Ethiopia & Kenya). The germplasm will be phenotyped for phenology, plant height, tillering, stay-green, biomass, grain yield, harvest index and various grain quality parameters.
  9. 9. Working together with the Queensland Government Highlights from the past year: Training Training in Australia for visiting scientists from Mali on sorghum crop improvement (Feb 2012).
  10. 10. Working together with the Queensland Government Highlights from the past year: Training African scientists from our GCP project attended the review of a related ACIAR project on stay- green in Hyderabad (Feb 2013).
  11. 11. Working together with the Queensland Government Highlights from the past year: Training Training in Ethiopia as part of a related BMGF project (April 2013).
  12. 12. Working together with the Queensland Government Highlights from the past year: Visit to Kenya (Kiboko)
  13. 13. Working together with the Queensland Government Training in Australia: February 2014 Four African sorghum breeders will be trained in Australia next February. West Africa • Clarisse Pulcherie Barro-Kondombo (Burkina Faso) • Aissata Mamadou Ibrahim (Niger) East Africa • Mohamed Yousif (Sudan) • Rachael Kamene Kisilu (Kenya)
  14. 14. Working together with the Queensland Government Genomics Simulation Modelling Data management Phenotypic data Integrated information that is better able to address complex quantitative traits Environmental characterisation Enhanced genetic gain Training on linking breeding, molecular & physiological aspects
  15. 15. Working together with the Queensland Government “What if” questions • What type of environments are common in our region? • What type of root architecture would work best in my current environments and management systems? • What combination of variation in root angle and row spacing would give the best yields on average at a particular location? What happens if I plant earlier? • What is the likely variation (risk) associated with growing the best combination? Root angle varies in sorghum germplasm Trait Biology G E M Crop model Historical weather and soil data Management options Crop Simulation Modelling: A Linking Technology
  16. 16. Working together with the Queensland Government Genome Resources: A Linking Technology Root angle varies in sorghum germplasm Trait Biology Genome resources (maps, markers, genes) Breeding program Genotypes and phenotypic data Questions we can answer • Are the genes for root architecture segregating in my breeding program? • Am I selecting for particular root architecture? • Are there other sources of the trait I should look at? • What impact does a particular gene for root architecture have in a specific environment? • Does variation in these genes have different effects in early flowering compared to late flowering genotypes?
  17. 17. Working together with the Queensland Government Product One Title: Backcross-derived lines containing stay-green introgressions. Description: 15 backcross-derived introgression lines (13 lines from F2_R04021-2/PI609084 and 2 lines from F2_R04003-2/PI585749). Use: Diverse drought-adapted germplasm for sorghum breeders to use in Mali, Niger, Burkina Faso, Ethiopia, Sudan and Kenya. Tangible products generated by our project
  18. 18. Working together with the Queensland Government Product Two Title: RIL populations segregating for the stay-green trait. Description: Four RIL populations developed by crossing an elite Australian stay-green female (R931945-2-2) with four male Malian lines (PI585749, PI585750, PI609084 & PI609114) totalling 917 individuals. Use: Mapping population for identifying drought resistance QTLs. Source of drought-adapted germplasm for African sorghum breeders. Tangible products generated by our project
  19. 19. Working together with the Queensland Government Product Three Title: F1 hybrids containing the stay- green trait. Description: Six F1 hybrids based on two Malian males (PI585749 & PI609278) crossed with three elite female parent lines from Australia (A1*9_B010054, A1*F_B963676 & F2_ms3*3_R931945-2-2) that contrast in the level of stay-green. Use: Drought-adapted germplasm for sorghum breeders to utilise. Tangible products generated by our project
  20. 20. Working together with the Queensland Government Impact of products on downstream beneficiaries Diverse drought-adapted germplasm for sorghum breeders to use in Mali, Niger, Burkina Faso, Ethiopia, Sudan and Kenya. It is anticipated that useful varieties will be developed with this germplasm and made available to small-holder farmers via the appropriate delivery pipeline (this will vary from country to country).
  21. 21. Working together with the Queensland Government How will these products be maintained and sustained? The diverse drought-adapted germplasm developed in this project will be incorporated into the various sorghum breeding programs in the six targeted countries. The germplasm will be maintained in the seed-stores from each of the sorghum breeding programs. Seed quality will be sustained by increasing seed on a regular basis. Key drought-adapted lines arising from the germplasm developed in this project could also be stored in centralised high-quality seed banks.
  22. 22. Working together with the Queensland Government Conclusions Drought-adapted sorghum germplasm has been developed for Africa and Australia. It is currently being evaluated in six African countries: Mali, Burkina Faso, Niger, Sudan, Ethiopia and Kenya. African sorghum breeders/physiologists from these countries are undertaking training in crop improvement, focusing on technologies that link genetics, genomics, molecular biology and crop physiology. Drought-adapted germplasm will be incorporated into the various African sorghum breeding programs based on selection by local breeders.
