As part of the MSU Project GREEEN (Generating Research and Extension to meet Economic and Environmental Needs) and in collaboration with Dave Douches and Julie Winkler our goal is to determine if existing potato cultivars grown in Michigan, which were developed primarily in the late-20^th century, will be impacted by altered CO₂ and temperature conditions anticipated in the mid-21^st century. Our specific objectives are to 1) use modeling techniques to evaluate the future agronomic growing conditions for potato in Michigan based on predictions for mid-century CO₂ concentrations and temperature and 2) utilize controlled growth chamber experiments to determine adaptability of current potato cultivars to climate conditions predicted for 2041-2070. We are currently assessing the physiological, agronomic and genomic responses of commercially grown chip processing cultivars to climate change projected for the mid-21^st century using 3 different climate change model simulations.
