Statewide Summary Tables
Top Yield Group Summary – Top Yield Group for hybrids across all locations. Some hybrids are not in every trial.
Varieties that were tested in all three regions. If a variety was not tested in all three regions, it has been excluded from these summary tables.
Hybrids for Refuge
This season, there were nine non-BT, Roundup Ready hybrids in the corn OVTs. Below are links to view a comparison of these seven side by side.
