Performance of Corn Hybrids in Alabama, 1976
Emmett L. 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.

VIRAL DISEASE REACTIONS OF SOME HYBRIDS IN 1976
Robert T. 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.
