C. Johnson and Darrell Williams 1 INTRODUCTION Corn hybrids are evaluated annually by the Alabama Agricultural Experiment Station in the Regular Corn Hybrid Test and the Preliminary Corn 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 36 to 40 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 plants per acre and thinned to 25,000. Grain yields were adjusted to 15.5 percent moisture and converted to bushels (56 pounds) per acre. Stalks broken or leaning more than 45 1 Respectively, Professor and Research Associate (resigned) of Agronomy and Soils. -l - 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. Grain and husk quality ratings are given as a regional average of the 1984 tests. The ratings were based on a 1 = excellent to a 5 = very poor system. The corn hybrid tests are examined for disease incidence each year by R.T. Gudauskas, Professor of Botany, Plant Pathology, and Microbiology. When virus or other disease symptons indicate crop damage, disease ratings are compiled and published in this report. Virus infection data from the test at Marion Junction are reported this year. 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 1984 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 45 value indicates an icrease in t he unacctet: cr variabiitv. Since the performance of hybrids varies with location anc year, long-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. -2- A committee comprised of Department of Agroncmy and Soils and Alabama Cooperative Extension Service personnel involved in corn research reviewed the past 3 years of corn hybrid test data to assemble the list of acceptable hybrids on page 26. The recommended 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 combination of all characteristics. -3- ACKNOWLEDGMENTS Appreciation is expressed to the following station superintendents and their staffs.

Vi 1W f OO i ------------- - - -- - - - - - - - - - - - - - - N) VIRAL DISEASE REACTIONS OF SOME HYBRIDS IN 1985' 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 (MDM), caused by the maize dwarf mosaic virus (MDMV). Discovery of MDM in the State dates back to the early 1960's, while MCD has been recognized only 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 MOM-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 MDMV is carried by some 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 MOM incidence and damage usually are high in corn fields thaz are hea~iy infested ih Use of resistant or tolerant corn hybrids and the control or avoidance of johnsongrass infested areas are the most practical controls for MCD and MOM. Commercial and experimental hybrids are evaluated yearly to identify resistant hybrids or promising sources of resistance prepared by Pobert T. Gudauskas, Professor and Acting Head of 3otany, Plant Pathology, and Microbiology. to the diseases. Results of evaluations of some commercial hybrids during 1985 are summarized in this report. Procedure Viral disease ratings were made on entries in the corn hybrid test at the Black Belt Substation, Marion Junction. Plants showing symptoms of MCD and/or MOM were counted and data are reported as percent incidence of the diseases for each hybrid. Results At the Black Belt Substation, incidence of MDM ranged from 0-6.1 percent among hybrids and averaged 2.1 percent for the entire test, table 9; incidence of MCD ranged from 0-29.4 percent and averaged 9.6 percent for the test. AgraTech brand GK850 showed no symptoms of either disease, and incidence of either disease was less than 5 percent in at least 11 other hybrids. Hybrids showing relatively greater resistance or tolerance were apparent. 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 gciven elsewhere in this recort. -14- TABLE 9.9 INCIDENCE OF VIRAL DISEASES IN PEGULAR CORN HYBRIDS TEST, MARION JUNCTION, AUGUST 2. 1985 1 Brand name Hybrid Maize chiorotic Maize dwarf dwarf mosaic AgraTech AgraTech Asgrow/O'Gal d DeKalb DeKalb DeKaib FFR FFR FFR Funk's Funk's Funk's Funk's Golden Harvest Golden Harvest Jacques McCurdy McCurdy Northrup King Northrup King Asgrow/O's Gold Asgrow/O's Gold Pioneer Pioneer Ring-Around Stauffer Sunbelt Sunbel t Todd Todd Z-; ilme rma n 7Z irmerma n 850 900 RX 404 DK 789 T 1230 DK 689 815 955 929 W G-4733 G-4779 W G-4734 G-4858 H-2660 W XC 918 .8400 84 AA 8150 PX 95 PX 87 33,44 5509 3147 3187 1502 S 7759 1802 1860 EX 810 E;4/' 82 0 7 1 - 27 '( 0 1.1 15.7 8.3 13.0 8.6 15.7 15.9 21.2 8.8 25.4 13.7 3.4 29.4 1.6 15.7 4.7 1.0 8.5 0 6.5 1.8 18.9 8.9 6.8 15.9 0 .0 0 0 2,0 5.8 4.0 5.8 27 3.1 2.1 100 2.9 0 4.99 1.*0 0 1.0 2.8 1.9 3.9 2.6 .9 .8 2.2 2.0 4o6 ,8 ,8 0 NI r(~lr rz~r~\l W1~I1 1l / -,-------------------- IRANOtNAM l-BIiYOi$RD3-YR. 2-YR. 1985 3-YR. 2-YR. 1985 IIIOSILK 1(SY - 1--------IiD: -MiA:? ------ ----------- WLtiLI hW..
