Thurlow and W.C. Johnson 1 INTRODUCTION Corn hybrids are evaluated annually by the Alabama Agricultural Experiment Station in the Regular Corn Hybrid Test and the Preliminary Corn Hybrid Test on a northern, central, and southern regional basis. The Marion Junction, or Black Belt Substation, corn test is used as the prairie soil regional comparison. Entries in the preliminary tests are both experimental and newly released hybrids. If a hybrid is outstanding in the preliminary test, it is entered in the regular corn test the following year. White and early corn hybrids are tested at one location in each region. One regular and one white corn hybrid test are irrigated at Headland in southern Alabama. The locations and cultural practices for the tests are shown in table 1. The tests were designed as a randomized complete block with four replications. Row width was 30 to 36 inches depending on location. Two-row plots were used, with row length ranging from 20 to 30 feet depending, again, on location. The target plant population for the tests was 20,000 plants per acre with a seeding rate of 23,000 seeds per acre. The irrigated tests at Headland were seeded at a rate of 30,000 plants per acre and thinned to 25,000. 'Respectively, Associate Professor and Professor of Agronomy and Soils. Grain yields were adjusted to 15.5 percent moisture and converted to bushels (56 pounds) per acre. Stalks broken or leaning more than 45 degrees were considered lodged. The mid-silk data measured the number of days from planting until one-half of the plants in the plots were showing silks. Bushel test weights are reported as regional averages from this year's data. To aid in determining real yield differences, a statistical analysis of variance is performed on the data from each location. The L.S.D. (least significant difference) and C.V. (coefficient of variation) are given for each location's test. The difference in yield of two hybrids must exceed the L.S. D. value for one hybrid to be considered superior to the others in yield in that particular test. The C.V. is a measure of the variability in an experiment. An increase in its value indicates an increase in the unaccounted variability. The corn hybrid tests are examined for disease incidence each year by R. T. Gudauskas, Professor of Plant Pathology. When virus or other disease symptomn indicate crop damage, disease ratings are compiled and published in this report (page 17). Virus infection data from the tests at Marion Junction, Prattville, Belle Mina, and Winfield are reported this year, tables 9 and 10. Since the performance of hybrids varies with location and year, lorng-term averages from several locations are more reliable than 1-year performance. Three-year regional averages are considered a reliable evaluation of the relative performance of hybrids. The irrigation test at Headland had 13.8 inches of water applied in 11 applications during May, June, and July to supplement the rainfall. Rainfall during June and July was extremely variable in 1990, table 21, which caused corn grain yields to vary by location. 6 A comittee comprised of Department of Agronany and Soils research and extension personnel involved in corn research reviewed the past 3 years of corn hybrid test data to assemble the list of acceptable hybrids on page 35. The recommened hybrids are not all equal in performance. Some are outstanding in one or more characteristics; while others may not be obviously outstanding, they might possess a satisfactory ccmbination of all characteristics. 7 ACKNCWIEDGMENTS Appreciation is expressed to the following supervisory personnel of the outlying units whose quality work makes this a reliable source of information for farmers in their areas.

AlinA ItCln ~rr~ cr~ v VIRAL DISEASE REACTIONS OF SCME HY DS IN 19902 The two most prevalent viral diseases of corn in Alabama are maize chlorotic dwarf (MCD), caused by the maize chlorotic dwarf virus (MCDV), and maize dwarf mosaic (MM), caused by the maize dwarf mosaic virus (MDE). Discovery of MI M in the State dates back to the early 1960's, while MCD has been recognized since 1973. Both diseases probably occur throughout Alabama; however, they generally have been more prevalent and damaging in the northern two-thirds of the State. Symptoms of the two diseases are similar in appearance and sometimes difficult to distinguish. Generally, affected plants are chlorotic or discolored and may be stunted. Leaves of MM diseased plants show an irregular, light and dark green mosaic or mottle; the initial symptom of MCD is a fine, chlorotic streaking over the smallest veins. The causal viruses are spread by feeding activities of insects. MCDV is transmitted by certain leafhoppers, and MEWV is carried by same aphids. Both viruses have similar host ranges among a variety of wild and cultivated grasses. Johnsongrass is an important overseason or reservoir host for the viruses, and MCD and M1M incidence and damage usually are high in corn fields that are heavily infested with johnsongrass. Use of resistant or tolerant corn hybrids and the control of johnsongrass or avoidance of johnsongrass-infested areas are the most practical control for MCD and MDM. Commnercial and experimental hybrids are evaluated yearly to identify resistant hybrids or prciising sources of resistance to the diseases. Results of evaluations of some commercial hybrids during 1990 are summarized in this report. 2Prepared by Robert T. Gudauskas, Professor of Plant Pathology. 17 Procedure Viral disease ratings were made on entries in the corn hybrid test at the Black Belt Substation, Marion Junction, and the Upper Coastal Plain Substation, Winfield. Plants showing symptaos of MCD and/or MDM were counted, and data are reported as percent incidence of the diseases for each hybrid. Results Levels of MCD and MI4M were unusually low in the tests at all locations, as was the case in the general corn crop throughout the State in 1990. The very low incidence of both diseases among and within hybrids at the Prattville and Marion Junction tests, tables 9 and 10, made any comparison of hybrid susceptibility meaningless. Although lower than usual, incidence of both diseases was more general in the tests at the two northern locations. In the test of 49 hybrids at the Tennessee Valley Substation, incidence of MDC ranged from 0 to 10.5 percent and averaged 1.2 percent; incidence of MIM ranged from 0 to 3.0 percent and averaged 0.3 percent. Nineteen hybrids showed no symptoms of either disease. At the Upper Coastal Plain Substation, incidence of MCD ranged from 0 to 5.8 percent and averaged 0.6 percent among the 49 hybrids in the test; that for MEM ranged from 0 to 11.6 percent and averaged 0.7 percent. Twenty-nine hybrids showed no symptm-s of either disease. Hybrids showing relatively greater resistance or tolerance were apparent at both locations. Under conditions of higher or lower incidence of viral disease, hybrids would be expected to retain their relative ranking. When selecting a hybrid, viral disease reactions should be taken into account for areas where the diseases are known or suspected to occur, along with the considerations of yield and other characteristics given elsewhere in this report. 18 Table 9.
