Preface

In this research report, the results of the 2000 corn performance trials are presented. Corn performance trials were conducted at six locations throughout Georgia (see map below) and two locations in Florida in 2000. Short-season, mid-season, and full-season hybrids were planted at Tifton, Plains, and Midville in the coastal plain region, at Griffin in the Piedmont region, at Calhoun in the limestone valley region, at Blairsville in the mountain region, and at Quincy and Jay in the panhandle region of Florida. High oil corn hybrids were tested at Tifton and Plains. Hybrids used for silage were evaluated at Tifton, Griffin, Calhoun, and Blairsville, Georgia, and at Quincy, Florida. Preliminary experimental hybrids were tested at Tifton only.

At each site all plots within a maturity group were seeded at the rates specified and not thinned, and the populations at harvest are included in the tables. Information concerning fertilization and cultural practices used in each trial is included with the tables. Grain harvesting was done with a small plot combine, and yields were adjusted to 15.5 percent moisture. Since data averaged over several years indicate a hybrid's yield potential better than data from only a single year, average yields over several years are included in this report.

The least significant difference (L.S.D.) at the 10 percent level has been included in the tables to aid in comparing hybrids. If the yields of any two hybrids differ by the L.S.D. value or more, they can be considered different in yield ability. Bolding is used in the performance tables to indicate hybrids with yields statistically equal to the highest yielding entry in the test. The standard error (Std. Err.) of an entry mean is included at the bottom of each table to provide a general indicator of the level of precision of each experiment. The lower the value of the standard error of the entry mean, the more precise the experiment.

Producers of hybrid seed corn are invited to enter their hybrids in the Georgia performance trials. Most hybrids entered are commercially available in Georgia, but a few experimental hybrids are also entered. Entry of a hybrid in these trials does not imply endorsement or recommendation by the University of Georgia College of Agricultural and Environmental Sciences.

This report is one of four publications presenting the 1999-2000 performance of agronomic crops in Georgia.

The Season

The 2000 corn season was hot, dry and early. Open weather in March and April allowed planting to progress a week ahead of average, although in many areas soil moisture was below normal. By mid-April, dry soils were a concern across the state. Planted acreage was estimated at 400,000. May was extremely dry. Tasseling and silking were ahead of average. By mid-June, more than 50 percent of the crop was in poor condition. Late June rains gave some relief from heat, but soil moisture levels remained below normal over much of the state. Drought conditions continued through July and August. The irrigated crop was generally good, but more than normal irrigation was needed. Some areas experienced water shortages and long periods of very high temperatures at critical development stages. Dryland crop results depended on spotty rainfall. Grain quality as well as harvest and storage insects were increased problems in some areas.

The drought conditions of 1998-1999 continued through the 2000 season. Rainfall at the six Georgia and Quincy, Florida, corn variety test sites is listed below. Total seasonal rainfall remained below normal for the season for the third consecutive year.

Of the 400,000 planted acres, only 340,000 were harvested at an estimated yield of 100 bushels per acre. The total production for the 2000 season was a 10 percent increase over 1999.

Mid- and Full-Season Corn Hybrid Performance, 2000, Irrigated Quincy, Florida

A mid- and full-season corn hybrid performance trial was conducted at this location during the 2000 growing season. However, high temperatures, disease, drought, and stand loss caused considerable variation in performance among plots within the test. Yields ranged from near 100 to 138 bushels per acre. After careful analysis and review of the data, it is the opinion of the editors that the results of this trial may not accurately reflect the performance potential of all test entries. Since this data could potentially be misleading if used in making decisions concerning hybrid selection, we have chosen not to present them in this publication. Results from this test will be provided upon request.

A short and a mid- and full-season corn hybrid performance trial was conducted at this location during the 2000 growing season. However, high temperatures, disease, drought, and stand loss caused considerable variation in performance among plots within the test. Yields ranged from 19 to 40 and from 33 to 57 bushels per acre for the short and the mid- and full-season, respectively. After careful analysis and review of the data, it is the opinion of the editors that the results of this trial may not accurately reflect the performance potential of all test entries.

Short and Mid-Season
A short and mid-season corn hybrid performance trial was conducted at this location during the 2000 growing season. However, high temperatures, disease, drought, and stand loss caused considerable variation in performance within the tests. After careful analysis and review of the data, it is the opinion of the editors that the results of this trial may not accurately reflect the performance potential of all test entries. Since this data could potentially be misleading if used in making decisions concerning hybrid selection, we have chosen not to present them in this publication. Results from this test will be provided upon request.

INSECT SCREENING RESULTS

Evaluation of Corn Hybrids for Resistance to Insects and Other Traits

N. W. Widstrom

Environmental conditions in Georgia during the 2000 growing season were favorable for buildup of insect populations large enough to cause damage to corn. Generally, this damage is greatest in late-planted corn left in the field for an extended period past maturity.

It is recommended that hybrids resistant to insects be planted. These hybrids are presently the only economical means, in late plantings, for the reduction of damage by corn earworm, fall armyworm, maize weevil, and pink scavenger caterpillar. Consult your local county agent and/or extension entomologist for additional control recommendations for other insects.

Percent yield losses attributable to all insects for individual hybrids varied from 0.5% to 6.6% and are reflected by VG, G, F, P, and VP ratings in the tables. Hybrids in the tests sustained average yield losses of 3.0%, and 3.9% in the full and mid-season, and short-season hybrid tests, respectively. The mean level of overall yield loss for all tests was 3.6%. Of the total loss, about 41% was attributable to ear injury by the corn earworm, 56% to the pink scavenger caterpillar, and 3% to the maize weevil. Losses to the pink scavenger caterpillar and maize weevil are based on damage by multiple generations of these insects as the corn dries in the field. Timely harvest will substantially reduce losses to these two insects.

Evaluations for resistance to corn earworm and fall armyworm, maize weevil, and pink scavenger caterpillar are given for hybrids in the tables following. Lettered ratings refer only to relative resistance to insects and are not indicative of yield. Thus, a hybrid rated poor for resistance to insects might possibly be among the highest yielders and vice-versa. See the yield data in other tables for this information.

Husk tightness ratings were assigned using a scale of 1 to 5, in which 1 = very loose and 5 = very tight. No average rating was less than 2.0 or greater than 4.0; therefore, only loose, medium, and tight ratings are given in the tables.

Both the hybrid tests (full and mid-season, and short-season) were planted April 26, 2000. Plantings were delayed in 2000 due to dry field conditions and cooler than normal temperatures. Plots were thinned to 20,000 plants per acre. Ratings for overall insect damage were completed during October.

Data for this section were compiled by J. M. Cook, J. C. Mullis, and C. A. Pearl of the United States Department of Agriculture, Agricultural Research Service, Insect Biology and Population Management Research Laboratory, and Georgia Coastal Plain Experiment Station, Tifton, Georgia.

1 L = loose husks, M = medium-tight husks, T = tight husks. 2 Overall resistance to insect injury evaluations were made on the basis of total percent damage to the ear by one or more of the following insect categories: corn earworm and fall armyworm, maize weevil, and pink scavenger caterpillar. Ratings were made on a scale from very good to very poor, where VG = very good, G = good, F = fair, P = poor, and VP = very poor.
