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 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 Plainview
- Early Maturity Trial - 105 Relative Maturity (RM) and earlier
hybrids
- Late Maturity Trial - 106 RM and later hybrids
Central Zone: Morris and Rosemount
- Early Maturity Trial - 95 RM and earlier hybrids
- Late Maturity Trial - 96 RM and later hybrids
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 2003. Reported yields are adjusted to 15.5% grain moisture.
Hybrids are ranked within a maturity group by moisture content
averaged
across
locations
for 2003.
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. 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.
