2024 was the final year of the corn grain variety trials. Trial results are shared in the spreadsheet below. See the University of Minnesota Extension's corn resources for more corn production information.

2024 corn grain variety trial narrative
The Minnesota Corn Evaluation Program was conducted by the University of Minnesota Agricultural Experiment Station to provide unbiased information for use by corn growers when they choose which brand of corn to buy and grow. The program was financed in part by entry fees from private seed companies that chose to place their entries for testing.
Test locations
Test zones, locations and maturities are as follows:
- Southern Zone: Lamberton and Waseca
- Central Zone: Rosemount
- Northern Zone: Crookston
Testing procedure
Entries: Seed corn companies choose their entries for each zone. Entries in each trial were based on the relative maturity (RM) provided by the company. The University of Minnesota Corn Testing Committee could also choose entries in each test. All locations tested three replications for each entry.
Presentation of data
Yields are given for individual locations along with yields and harvest moisture contents averaged across locations for 2024. Reported yields are adjusted to 15.5% grain moisture. Entries are ranked within a maturity group by moisture content averaged across locations for 2024.
Identification of traits
Genetic modifications of entries will be identified using generic terms to describe the trait without identifying the specific event for genetic modification. For example Bt will identify genetic modification for corn borer resistance but will not differentiate between the Bt 11 event, the YieldGuard corn borer event or the Herculex corn borer event. Identifiers will be:
- BT = European corn borer resistance
- CRW = Corn rootworm resistance
- Gly = glyphosate herbicide resistance
- LL = Liberty herbicide resistance
- Enlist = 2,4-D choline + FOPS
Least significant difference
The LSD (Least Significant Difference) figures at the bottom of the yield columns in the tables are
statistical measures of variability in the trials. These values may be used to determine whether the difference between any two entries is likely to be a real difference or just natural variation.
If the yield difference between two entries is equal to or greater than the LSD, then one can be confident that the two entries probably differ in yield potential. We show LSD values with a 0.2 alpha level, which means that when two entries differ in yield by the LSD value or more one can be 80% confident that the two entries differ in yield potential.
The higher-yielding one is the better entry from the yield standpoint. If the yield difference between two entries is less than the LSD, the two entries probably do not differ significantly in yield potential.
