1 2005 New York Hybrid Corn Grain Performance Trials Plant Breeding and Genetics

2 Margaret E. Smith Phone: Associate Professor Fax: Department of Plant Breeding and Genetics College of Agriculture and Life Sciences G42 Emerson Hall Ithaca, NY TO: Persons interested in the grain yield performance of corn hybrids in New York This report includes a summary of our 2005 commercial hybrid corn grain trials. It shows results from 11 locations in New York, divided into the following four maturity ranges: Growing Degree Days Relative Maturity Early GDD Days Medium Early GDD Days Medium GDD Days Long Season GDD Days This report is designed to aid seed company representatives, corn growers, and extension educators in evaluating hybrids for yield capacity, stalk and root strength, maturity, and test weight in various regions in New York. It also provides information for developing ratings for the Cornell Guide for Integrated Field Crop Management. While many hybrids included in this report are widely grown varieties, others are new or experimental hybrids. In considering these tables, remember that this data represents only one year. Test results should be considered over several years before final conclusions are valid. Results gathered over several locations are a better guide than results at any one location. We welcome comments or suggestions for improving this report for your use. Sincerely yours, Margaret E. Smith Department Extension Leader For information on entering hybrids in the 2006 trials, please contact Judy Singer or Margaret Smith at /2006 PB&G Building Strong and Vibrant New York Communities Cornell Cooperative Extension provides equal program and employment opportunities. NYS College of Agriculture and Life Sciences, NYS College of Human Ecology, and NYS College of Veterinary Medicine at Cornell University, Cooperative Extension associations, county governing bodies, and U.S. Department of Agriculture, cooperating.

3 2005 Growing Conditions The 2005 growing season in NY started off cool and dry but then turned hot and dry. A wetter than average period in October made the seasonal rainfall totals appear more like a normal season, but in most cases that is not what the corn crop saw! May was cool and dry throughout the state, with most locations recording about 90 growing degree days below normal for the month and only about one-third to one-half of the normal rainfall. Most corn fields were planted in a timely manner, but most also had a number of late emerging plants due to a combination of dry soil conditions, poor seed-soil contact, and non-uniform moisture that caused some seeds to remain dormant until a passing shower provided moisture for germination. This often resulted in a lot of variation in plant size within a field. We observed some ankle-high corn next to kneehigh corn in early July. The dry conditions right after planting also resulted in weed control failures in a number of fields. The months of June, July, August, and September were hotter than normal. Hot dry times during the early development of the corn crop often made plants shorter than normal. All of our sites received from 105% to 120% of the normal heat for the growing season. This resulted in unusually dry grain at harvest time, with our harvest grain moistures in the high teens or low twenties. The wet conditions in October made timely harvest a challenge in some cases. Despite the erratic summer rainfall in many parts of the state, our state average corn grain yield was a record high 124 bu/a. Local weather data and details about the conditions at each site are provided on the data tables on the following pages. Testing Procedures Regional test locations for 2005 are shown on page iii-. Tests were planted in 1/500 acre plots with three replications per location. All sites were machine planted and combine harvested except Chazy, which was harvested by hand. Plot grain weights, grain moisture percentages, and test weights were measured electronically on the combine for most sites. Grain yields were adjusted to 15.5% moisture for computation and comparison. Test Weight We have again included test weight data (Test Wt). This data was taken during harvest by measurement in a test weight chamber in the weighing assembly on our combine. The figures represent unadjusted test weight measurements of freshly harvested grain. Experience tells us that test weight is influenced by moisture content of the grain (generally the higher the moisture the lower the test weight) and by the genetic potential of the hybrid. This information is presented to be helpful, but farmers should discuss this further with their seed dealers if test weight is important in their marketing plans. The values shown here may or may not reflect the comparative test weights of dry grain. Consider the comparative moisture ratings of the hybrids when looking at test weight values. -i-

4 Yield Moisture Ratio We have included a yield to moisture ratio (Y/M Ratio), which is the grain yield in bu/a divided by the percentage grain moisture. Some breeders use this number as an estimate of hybrid efficiency. Hybrids that show high yields and earlier maturity (lower moistures) have higher Y/M ratios. Standability Ratings We have again used two methods for reporting standability, both assessed at the time of grain harvest. The first method is the "hand push" (Stndability) rating system. The stalks are pushed, by hand, and resistance to pushing and breaking is rated on a scale from 1 to 9. A rating of 9 indicates that stalks have strong resistance against breakage when pushed. Lower ratings indicate less resistance to pushing and more down plants. The second method is based on an actual count of stalks broken (or lodged) below the ear and is expressed as a proportion of the total number of plants in the plot (% Stalk Ldg). CV, LSD, SD We have used three statistics to evaluate the quality of the data from these experiments. The CV (coefficient of variation) is a measure of the amount of uncontrolled variability due to differences in the soil, weather, fertility, etc. Grain yield CVs below 12 are excellent and those 15 and under are good. The LSD (least significant difference) is computed at the 5% level of probability. This indicates that if a difference between two hybrids is larger than the listed LSD, then the odds are at least 95 to 5 (or 19 to 1) that there is true varietal difference between the hybrids, or, as the statisticians say, the difference between the two hybrids is "significant." Farmers who need businessmen's odds more than statistical precision may consider a 10 bu/a grain yield difference sufficient to guide a decision in choice of hybrid. The SD (standard deviation) is the measure used to determine whether the differences between two hybrids are large enough, given the precision of that experiment, to be significant and probably due to true differences between the hybrids.
