Cardeni/ Corn hybrids are evaluated annually at 12 locations in the regular corn variety testing program of the Auburn University Agricultural Experiment Station. In addition, preliminary tests are conducted at 6 of the 12 loca- tions. Entries in the regular tests have been tested one or more years and have performed well in the preliminary tests. Entries in the preliminary tests are experimental or newly released hybrids that may have potential for use in Alabama. If a hybrid is outstanding in the preliminary tests it is is entered in the regular testing program the following year. Severe drouth during most of the 1977 growing season caused reduced yields at all locations. At most locations, moderate to heavy insect populations (primarily armyworms) caused further yield reductions and poor grain quality. It is likely that yields of some hybrids were affected by timeliness of showers in relation to their stage of growth; therefore, the 1977 data should be viewed with caution. However, regional averages over 3 or more years should give a reliable indication of the relative performance of hybrids in the regions indicated. In central Alabama, at Camp Hill, Miilstead, Prattville, Marion Junction, and Camden (non-irrigated), yields were near zero, and data from these locations are not included in this report. Data from the 1976 Corn Variety Report are included and should be used to assist in selecting hybrids for use in central Alabama. Yields from the irrigated variety test at Camden were good, and 1977 yields of this test are included in the report. -Research Associate, Department of Agronomy and Soils. Locations of the tests, cultural practices, and final plant popula- tion are shown in table 1. All entries at a location were treated the same. The experimental design was a split block with 4 replications. Row width was 36 to 42 inches depending on location. At Crossville, Winfield, and Camp Hill, one-row plots 60, 30, and 40 feet long, respectively, were used. At the other locations, 2-row plots were used with row length varying from 20 to 25 feet depending on location. Regional averages for 3, 2, and 1 years in northern Alabama are presented in tables 2, 3, and 4, respectively. Table 5 shows yields by locations, and regional average yields for 1-5 years in northern Alabama. Similar data are given for southern Alabama in tables 10-13. Regional averages for 3, 2, and 1 years (1974-76) in central Alabama are given in tables 6-8. Table 9 shows yields by location, and regional averages for 1-5 years in central Alabama (1972-76). Data from Marion Junction during 1974-76 are given in tables 17-19. As discussed above, 1977 data from non-irrigated central Alabama tests are not included. The performance of corn hybrids grown under irrigation at Camden for 3, 2, and 1 years is given in tables 14-16. This test consisted of 2-row plots 20 feet long. Row width was 36 inches in 1977 and 30 inches in 1975 and 1976. Results of the preliminary tests are given in tables 25-26. The corn variety tests are examined each year for viral and other disease symptoms by Dr. R. T. Gudauskas, Department of Botany and Micro- biology. When disease symptoms indicate that damage may occur, disease ratings are compiled and published in this report. In 1977, due to insect damage and premature dry-down, disease symptoms were masked and meaningful ratings could be taken. Viral disease ratings from the 1976 Corn Variety Report are given in tables 20-24. When comparing hybrids, small differences in yield may not be real differences but may result from variations in the plots and testing procedures. To aid in determining real differences between hybrids a statistical proce- dure, 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, particularly in a year like 1977 when drouth and insect damage greatly affected yields, long term averages from several locations are more reliable than 1-year averages when evaluating a hybrid from an area. Three-year results are considered sufficient to give a good indica- tion of the relative performance 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, All 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 characteristics. All characteristics should be carefully considered when selecting a hybrid. ACKNOWLEDGMENT Appreciation is expressed to the following individuals who furnished information for this report: J. T.

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 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 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 NDM. Commercial and experimental hybrids 30 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 discolored; 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- fourths 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 31 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%, DM - 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. 32 33 Table 20.
