RESULTS

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 entr 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 Lewiston
       Early Maturity Trial - 105 Relative Maturity (RM) and earlier
       Late Maturity Trial - 110 and 115 RM
Central Zone: Morris and Rosemount
       Early Maturity Trial - 95 RM and earlier
       Late Maturity Trial - 100 and 105 RM
Northern Zone: Staples and Rothsay

Testing Procedure

Entries: Each corn seed company could enter up to six hybrids per 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. For this reason, there may be more than six hybrids for a company in a test.

Presentation of Data

Yields are given for individual locations along with yields and harvest moisture contents averaged across locations for 1998. Hybrids are ranked within a maturity group by moisture content averaged across locations for 1998.

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 if the difference between any two hybrids is likely to be a real difference rather than 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. 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.
