Alignment with RFA Project addresses following focal topics of RFA (p. 5): • • • • meeting the caloric demands of population growth; improving crop health; adapting crops to climate change; and lessening their footprint on the environment. Drought tolerant line in Uganda Sunflower oil in Serere, Uganda Project Overview Crop Germplasm (Activity 1) • GWAS of drought, salt, flood, nutrient stress - HTP + traditional phenotyping • Mechanistic analyses of stress resistance + • • • • Wild Relatives (Activity 2) • Population genomics of stress resistance - Range-wide sampling of extremophile species - Environmental data (climate, soil, water) Crop + Wild (Activities 3-6) Development & characterization of MAGIC populations (Activity3) Functional analyses of candidate genes (Activity 4) GE3LS – Develop crop yield models (Activity 5) GE3LS – Explore how international treaties impact germplasm use (Activity 6) Anticipated Scientific Outcomes and Deliverables Scientific Outcomes: • System level understanding of abiotic stress resistance • Validation of candidate genes, potential extension to other oilseeds Deliverables: • "Next generation” germplasm resources • Central data mining and analysis resource • Models for predicting yields of resistant sunflower cultivars across Canada • Strategic recommendations for mitigating barriers to R&D caused by treaties Project Team BIOINFORMATICS Burke (U.
