VIRGINIA CORN HYBRID TRIALS IN 2002

Performance trials of commercial corn hybrids were conducted at seven locations in Virginia in 2002. One location consisted of an irrigated and a non-irrigated test. Test weights were taken with a GrainGauge manufactured by HarvestMaster and calibrated over six years of testing. A list of the companies participating in the trials is shown above. All hybrids entered in the Virginia trials were those submitted by commercial companies. The locations at which particular hybrids were entered were specified by the company. Companies entering hybrids were charged a fee for each hybrid per location to support the Corn Performance Trials.

All locations except Orange were planted with a Wintersteiger PlotKing 2600. Orange was planted by hand and thinned to the desired population. All locations except Orange were harvested with a Massey-Ferguson 8XP plot combine. Orange was hand-harvested and shelled to obtain grain weights. Yields have been adjusted to 15% moisture.

Yield Differences

Experimental plots vary in yield and other measurements due to location in the field and other factors which cannot be controlled. Statistics given in the tables are intended to help the reader make valid comparisons between hybrids. The magnitude of differences which may have been due to uncontrollable variation has been computed for the data and listed at the bottom of columns as the LSD (.05) (least significant difference with 95% confidence). Differences less than the LSD are assumed not to be real differences with 95% confidence.

Choice of Hybrids

When making hybrid selections it is important to realize that hybrids differ in their performance under different environments. Some hybrids are more adapted to a wide range of environments. Hybrid performance may vary with year and location variations in rainfall, temperature, pests and other environmental variables. In these experiments, many hybrids have essentially the same yield, and great care should be taken in interpreting the results of a single year's tests, especially at only one location. For these reasons it is important, whenever possible, to also look at a hybrid's average across locations when making hybrid selections. Multi-year averages give even greater confidence to hybrid performance decisions. The relative yield tables compare the yield of a hybrid to the average yield of all hybrids in the test. These tables are an excellent summary of yield potential compared to other hybrids.

* Relative yield is calculated by dividing the yield of a hybrid by the average yield of all hybrids of all maturities at that location. A hybrid with a relative yield of 105 was 5% above the average of all hybrids at that location. The value of 105 is not a yield but a value relative to all other yield values at that location. Relative yields are listed in order of descending mean values.

Corn silage trials were conducted at four locations in Virginia in 2002. All hybrids entered in the Corn Silage Variety Trials were those submitted by commercial companies. Companies entering hybrids were charged a fee for each hybrid to support the Corn Silage Variety Testing Program. Company representatives selected the maturity groups into which hybrids were entered. Guidelines are as follows:

VE Very Early <105 days
E Early 105-114 days
M Medium 115-120 days
L Mid/Full Season 120+ days.

Yields are reported as harvested (at the dry matters indicated) and as adjusted to 35% dry matter. Adjusted yields are better for making hybrid comparisons. Hybrids have been ordered by descending yields adjusted to 65% moisture. The least significant differences (LSDs) are an indicator of the amount of variation that was observed across the samples within maturity groups. For each characteristic, we can be 95% sure that two varieties are truly different only if they differ by the amount of the LSD or more. It is recommended that in selecting corn varieties for silage, select first those
