Performance of Corn Hybrids in Alabama, 1978
Cliff G..Currier_
/
Corn hybrids are evaluated annually at 12 locations 
in the regular
corn variety testing program of the Auburn University 
Agricultural Experi-
ment Station. Preliminary tests are conducted 
at 6 of the 12.locations.
Entries in the regular 
tests have been tested 
one or more years and have
performed well in the preliminary 
tests. Entries in preliminary tests 
are
experimental and released hybrids that 
are new to_.the Alabama variety tests.
If a hybrid is outstanding in the preliminary 
tests it is entered into the
regular testing program the following year.
Rainfall distribution was poor in northern 
and central Alabama during
the 1978 growing season. In these two regions yields were low except at
Belle Mina. In southern Alabama all locations except 
Monroeville had
average test yields over 100 bushels per acre. 
At Headland a total of 4
inches of irrigation water was applied in three applications during the
month of June to- supplement rainfall. Generally, yield 
reduction was due
to the lack of adequate moisture during the period of highest need for
moisture .by the corn hybrids.
Locations of the tests, cultural practices, and 
average plant popula-
tions are shown in table 1. All hybrids 
at. a location were treated the same.
The experimental design was a randomized 
complete or split block design with
four replications. Row width was 36 to 42 inches 
depending on location.
At Camp Hill, one-row plots 40 feet long were used. 
At all other locations,
two-row plots were used with row length varying from 
18 to 30 feet depending
on location. The target plant population for all tests 
was 22,000 plants per

acre. The seeding rate was 25,300 seeds per acre based on plot size at
each location. At Crossville a higher seeding rate was used for both the
regular and preliminary tests. The target plant population for the irri-
gated test at Camden was 26,000 plants per acre, with a seeding rate of
29,700 seeds per acre. It was apparent that each location had different
amounts of plant survival.
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. Ear rot, earworm damage, size of grain, and luster
of grain were used in rating grain quality. Height of ears was measured fror
the base of the ear to ground level. Husks were rated according to tight-
ness and extension beyond the tip of the ear. Mid-silk data measured the
number of days from planting until one half of the plants in the plot were
showing silks.
Data from the 1975, 1976, and 1978 tests at Marion Junction are given
separately and should be used to assist in comparing hybrids grown under
conditions of high incidence of virus infection. Yields from the irrigated
variety test at Camden were good. The 1978 yields and the 2- and 3-.year
-averages from this test are included in the report.
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 loca-
tion, and regional average yields for 1 to 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 grown and irrigate
at Camden for 3, 2, and 1 years is shown in tables 14, 15, and 16 respectivel
In 1978, this test was sprinkler irrigated on June 30, July 5, 10, and 19.
Approximately 2 inches of irrigation water was applied over this period of
2
time. Performances of corn 
hybrids at Marion Junction for 
3, 2, and 1
years are given in tables 
17, 18, and 19 respectively. 
Results of the
preliminary tests are given in tables 21-23.
The corn variety tests are examined 
each year for viral and other
disease symptoms by Dr. R. T. Gudauskas, Department 
of Botany and Microbiology.
When disease symptoms indicate that 
damage may occur, disease ratings are
compiled and published in this 
report. An introduction and discussion 
of
procedure and results are given, and virus 
infection data from the variety
test at Marion Junction are given in table 
20.
When comparing hybrids, small differences 
in yield may not be large
enough to be considered real differences. To 
aid in determining real
differences between hybrids a statistical procedure, analysis 
of variance,
was performed on the data from each location. 
The L.S.D. (least significant
difference) is given for yields at each location in 1978.
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 
from an area. Three-year
results are considered sufficient to 
give a good indication 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. Then the composite score 
was obtained by subtracting
weighted values for lodging, quality, and ear 
height from this yield. The
value subtracted for each characteristic was 
proportional to the numerical
values shown for the characteristics in tables 
2, 6, and 10.

All 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-
ters. All information should be carefully considered when selecting a
hybrid.

VIRAL DISEASE REACTIONS OF SOME HYBRIDS IN 1978
Robert T. Gudauskas
Department of Botany and Microbiology
I NTRODUCTION
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 prac-
tical control for MCD and MDM. Commercial and experimental 
hybrids and
inbred lines are evaluated yearly to identify resistant 
hybrids of promising
35
sources of resistance to the diseases. Results of evaluations of some
commercial hybrids during 1978 are summarized in this report.
PROCEDURE
Viral disease ratings were made on entries in the corn variety test
at the Black Belt Substation, Marion Junction. 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 discoloration 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 the variety test on the Black 
Belt
Substation are given in table 20. Tests on the Piedmont, Tennessee Valley,
Sand Mountain, and Upper Coastal Plain substations were also examined but
disease incidence was insignificant.
With on exception, MCD and MDM were found in every hybrid in the Black
Belt test. Average incidence of MCD within all hybrids was 55% as compared
to 15% for MOM. Occurrence of both diseases in the same plant was frequently
observed.
36
Hybrids showing relatively greater_ res istance 
or tolerance were apparent.
Under conditions of higher or lower incidence 
of viral diseases many hybrids
would be more or less 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.
