CardernI / Corn performance tests were conducted at 12 locations by the Auburn University Agricultural Experiment Station in 1976. These tests are conducted annually to determine the relative performance of many hybrids offered for sale in Alabama and to furnish unbiased information which growers may use to evaluate hybrids. They are designed to compare hybrids in an area and are not intended to measure absolute yielding potential of a hybrid. Rainfall distribution was good in northern and southern Alabama during the 1976 growing season, and excellent yields were obtained in these areas. Yields of several hybrids exceeded 190 bushels per acre at Fairhope. Cen- tral Alabama yields were reduced by drought at all locations except Camp Hill. Location of the tests and cultural practices used are shown in Table 1. Lime and fertilizer were applied in adequate amounts as indicated by soil tests. Chemical and/or mechanical weed control practices were employed as needed. A split block experimental design with four replications was used at all test locations. Grain yields were adjusted to 15.5 percent moisture and converted to bushels (56 pounds) per acre. Stalks broken below the ear or leaning more than 45 degrees were considered lodged. Ear rot, earworm damage, size of ear and grain, and luster of grain were considered in rating ear and grain quality. Height of ears was measured from ear base to the ground level. Husks were rated according to tightness and extension beyond the tip of the ear. Regional averages for 3, 2, and 1 years in northern Alabama are pre- sented in tables 2, 3, and 4, respectively. Table 5 shows yields by location I/Research Associate, Department of Agronomy and Soils. and regional average yields for 1-5 years in northern Alabama. Similar data are given for central Alabama in tables 6-9, and for southern Alabama in tables 10-13. The performance of corn hybrids planted in 30-inch rows and irrigated at Camden for 3, 2, and 1 years is shown in tables 14, 15, and 16 respectively. In 1976, this test was furrow irrigated on June 16, and 24; and July 2, 13, and 23. Approximately 2 inches of water was applied at each irrigation. Performance of corn hybrids at the Black Belt Substation, Marion Junction, for 3, 2, and 1 years is given in tables 17, 18, and 19 respectively. A new section entitled Viral Disease Reactions of Some Hybrids in 1976, is included in this report. This section was compiled by Robert T. Gudauskas, G. W. Karr, Jr., and Clauzell Stevens, Department of Botany and Microbiology. An introduction and discussion of procedure and results are given, and data from several locations are presented in tables 20-24. This section will be of particular interest to growers in areas where viral diseases occur. At several locations preliminary tests were conducted to evaluate newly released and experimental hybrids. Results of these tests are given in tables 25-27. If a hybrid is outstanding in these preliminary tests it is included in the regular testing program the following year. When comparing hybrids, small differences in yield may not be real differences but may result from variation in the plots and testing procedure. To aid in determining real differences between hybrids a statistical pro- cedure, analysis of variance, was performed on data from each location. The L.S.D. (least significant difference) is given for yields at each location. Since performance of hybrids may vary from year to year and location to location, long term averages from several locations are more reliable than 1-year averages when evaluating a hybrid for an area. Three-year results are considered sufficient to give a good indication of the perfor- mance of hybrids. A composite rating system was used to determine the list of acceptable hybrids. The 3-year regional average grain yield of a hybrid was used as a base point. The composite score was obtained by subtracting values for lodging, quality, and ear height from its yield. The value subtracted for each characteristic was proportional to the numerical value shown for the characteristics in tables 2, 6, and 10. Hybrids that have an exceptionally good record for 2 years in the regular test was included on the acceptable list with a conditional notation. However, data from 3 or more years are normally used in evaluating hybrids. All of the acceptable hybrids are not equal in performance. Some are outstanding in one or more characteristics. Others may not be outstanding in any one characteristic but possess a satisfactory combination of charac- teristics. All characteristics should be carefully considered when selecting a hybrid.

Gudauskas, G. W. Karr, Jr., and Clauzell Stevens Department of Botany and Microbiology INTRODUCTION Presently, 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 MDM-diseased plants show an irregular, light and dark green mosaic or mottle; the initial symptom of MCD is a fine, chlorotic streaking over smallest veins. The causal viruses are spread bey 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 MDM incidence and damage usually are high in corn fields that are heavily infested with johnsongrass. Use of resistant or tolerant corn hybrids presently is the most practical control for MCD and MDM. Commercial and experimental hybrids 29 and inbred lines are evaluated yearly to identify resistant hybrids or promising sources of resistance to the diseases. Results of evaluations of some commercial hybrids during 1976 are summarized in this report. PROCEDURE Viral disease ratings were made on entries in corn variety tests at six locations. Plants showing symptoms of MCD and/or MDM were counted and data are reported as percent incidence of the diseases for each hybrid. Average disease severity for each hybrid was calculated from ratings of individual plants on a 1-9 scale, where 1 - no visible symptoms, 2 = upper two or three leaves chlorotic or discolored; no stunting, 3 = all leaves above ear chlorotic or discoloted; no stunting, 4 = general chlorosis or discoloration above ear; some stunting, 5 = general chlorosis or discolora- tion above the ear; plants stunted and ear reduced in size, 6 =upper three- foiths of plant chlorotic or discolored; plants stunted and ear reduced in size; 7 - entire plant chlorotic or discolored and stunted; small ear, 8 = entire plant chlorotic or discolored, stunted; no ear produced, 9 = plant dead; no ear. RESULTS Evaluations for viral diseases in variety tests on the Black Belt, Piedmont, Tennessee Valley, and Upper Coastal Plain substations are given in tables 20-24. Tests on the Main Station and Sand Mountain Substation were also examined but disease incidence was insignificant. Highest overall disease incidence and severity occurred in the test on the Black Belt Substation; average incidence and severity for all hybrids 30 were 59% and 3.26, respectively. Incidence of MCD and MDM was not separated at this location. Virus ratings were made on the first planting of the test which was not harvested because of poor stand and damage to viral diseases; yield data are from the second planting. Viral disease reactions were comparatively lower at the other locations. Average incidences of the two diseases were: Piedmont Substation, MCD - 14.5%, MDM - 5.9%; Tennessee Valley Substation, MCD - 12.8%, MDM - 11.3%; Upper Coastal Plain Substation, regular variety test, MCD - 29.4%, MDM 5.8%; preliminary variety test, 23.4%, MDM - 4.6%. Hybrids showing relatively high resistance or tolerance were apparent at each location. Under conditions of higher incidence of viral diseases many hybrids would be more susceptible but should retain their relative ranking. When selecting a hybrid, viral disease reactions should be taken into account for areas where the diseases occur, along with consideration of yield and other characteristics given elsewhere in this report. 31 32 Table 20.
