Adapting crops to increasing atmospheric carbon dioxide locations
Aims

To gain knowledge that will allow the Australian grains industry to maintain productivity by adapting crops and cropping systems to the effects of elevated CO2.

Key messages
  • Elevated atmospheric carbon dioxide (CO2) increases yield of grains, but whether future yields increase depends on rainfall and temperature changes.
  • Wheat grain protein decreases with elevated CO2.
  • Breeding new cultivars will allow adaptation to increasing CO2.
