Accomplishments
1. Similar genetics will support productivity gains and climate resilience in maize. Continued increases in maize productivity will be needed to support increasing demand. Changes in climate will require maize hybrids with different characteristics to maintain and increase productivity. Researchers in Ames, Iowa, used a modeling approach to predict how maize hybrids might need to be changed in response to changes in climate. The changes in hybrid characteristics needed to sustain increases in productivity were found to be very similar to the changes needed to sustain increases in the current climate. This research is significant because it demonstrates that similar breeding approaches and genetics will enable us to sustain productivity increases in the face of a changing climate which will inform breeders on how to adapt breeding programs for future genetic gain.
