Results of the Minnesota Corn Hybrid Evaluation Program are presented in this bulletin. The program was conducted by the University of Minnesota Agricultural Experiment Station to provide unbiased information for use by corn growers when they choose hybrids to buy and grow. The program was financed in part by entry fees from private seed companies that chose to enter their hybrids for testing.


TEST LOCATIONS


Test zones, locations and maturities are as follows:

Southern Zone: Lamberton, Waseca and Rochester
Early Maturity Trial - 103 Relative Maturity (RM) and earlier hybrids
Late Maturity Trial - 104 RM and later hybrids

Central Zone: Morris and Rosemount
Early Maturity Trial - 96 RM and earlier hybrids
Late Maturity Trial - 97 RM and later hybrids

Northern Zone: Staples, Rothsay and 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 and enter hybrids 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 2009. Reported yields are adjusted to 15.5% grain moisture. Hybrids are ranked within a maturity group by moisture content averaged across locations for 2009.
 

Identification of Traits

Genetic modifications of hybrids 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 events.

Identifiers will be:
Bt = European corn borer resistance
CRW = Corn rootworm resistance
GLY = glyphosate herbicide resistance
LL = Liberty herbicide resistance
 

Least Significant Difference

The LSD (Least Significant Difference) figures at the bottom of the yield columns in the tables are statistical measures in variability in the trials. These values may be used to determine whether the difference between any two hybrids is likely to be a real difference or just natural variation.

If the yield difference between two hybrids is equal to or greater than the LSD, then one can be confident that the two hybrids probably differ in yield potential. We show LSD values with a 0.2 alpha level which means that when two hybrids differ in yield by the LSD value or more, one can be 80% confident that the two hybrids differ in yield potential. The higher yielding one is the better hybrid from the yield standpoint. If the yield difference between two hybrids is less than the LSD, the two hybrids probably do not differ significantly in yield potential.
