Exploitation of Global Genetic Resources in wheat and maize
to address
•Food Security
• Climate change

Mission StatementDevelopment of the genetic and associated
technologies for the exploitation of genetic resources
to empower the global maize and wheat breeder
communities to address the challenges to global food
security including climate change and resource
scarcity (energy, water, nutrient and land).

Targeted Exploitation of Global Genetic Resources
There have been periods in the history of the earth when elevated CO2 and temperature were experienced
Target the genetic resources through FIGS

Biotic StressesMore difficult to predict
Anticipate: changed global distribution, changes in severity, new diseases
Problem or has potential to be a problem
Sufficiency of current R&D
Resistance potentially available in elite material
