Performance of Corn Hybrids in Alabama, 
1980
Cliff G. Currier
I
Corn hybrids are evaluated 
annually at 12 locations in 
the regular
corn hybrid testing program of 
the Auburn University Agricultural 
Experi-
ment Station. Preliminary tests 
are also conducted at one location 
in
each region. Entries in preliminary 
tests are both experimental and
newly released hybrids that have 
not been tested in the regular 
tests.
If a hybrid is outstanding in the preliminary 
tests it is entered into
the regular testing program the following 
year. White corn hybrids are
tested at one location in each region.
Rainfall distribution was fair to 
poor depending on location during
the 1980 growing season (table 
1). Good yields were obtained at Fairhope,
Brewton, Headland, and Prattville. 
Test yields at other locations averaged
less than 60 bushels per acre. 
Generally, yield reduction was 
due to
the lack of adequate rainfall during 
the period of greatest need for
moisture by the hybrids in the tests. 
All data from the E.V. Smith
Research Center, near Shorter,were not reported due 
to low and erratic
yields.
Location of the tests, cultural practices, 
and average plant popula-
tions are shown in table 2. All 
hybrids at a location were treated 
the
same. The experimental design was 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 varying 
from 18 to 30 feet depending
on location. The target plant population 
for all tests was 20,000 plants
per acre, with a seeding rate of 23,000 seeds 
per acre. The target plant

Soils.
population for the irrigated test at Headland was 26,000 plants per acre,
with a seeding rate of 30,000 seeds per acre. After thinning,imost loca-
tions obtained the target plant population in all plots.
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,and
color of grain were used in rating grain quality. Height of ears was
measured from ground level to the base of the ear. Husks were rated
according to tightness and extension beyond the tip of the ear. The mid-
silk date measured the number of days from planting until one half of
the plants in the plots were showing silks.
Regional averages for 3, 2, and 1 years in northern Alabama are pre-
sented in tables 3, 4, and 5,respectively. Table 6 shows yields by
location, and regional average yields for 1 to 5 years in northern Ala-
bama. Similar data are given for central Alabama in tables 7-10, and for
southern Alabama in tables 11-14. Yields from the irrigated test at
Headland were excellent. Two-and 1-year averages for the irrigated test
are shown in tables 15 and 16,.respectively. In 1980, approximately .1-
inch of sprinkler irrigation water was applied on June 3, 8, 12, 17, July
3, 72 10, 14, and 25. Approximately 9 inches of irrigation water was
applied over this period of time. Data from the test at .Mirion Junction
are given and should be used to assist in comparing hybrids grown in that area.
Performance of corn hybrids at Nharion Junction for 3, 2, and 1 years are
given in tables 17, 18, and 19,respectively. Yields and other characte-
ristics of white corn hybrids grown at Crossville and Headland are given in
tables Z0-21. Results of the preliminary tests are given tables 23-24.
The 1980 results of the preliminary and white corn test grown at the
E.V. Smith Research Center are not shown due to extremely low yields.
The corn hybrid tests are examined each year for viral and other
disease symptoms by Dr.-R. T. Gudauskas, Department of Botany, Plant
Pathology, 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. Virus infection data from the hybrid test at Marion Junction
are given in table 22.
When comparing hybrids, small differences in yield may not be large
enough to be considered real differences. To aid in determining real
differences between yields a statistical procedure, analysis of variance,
was performed on the data from each location. The L.S.D. (least sig-
nificant difference) and C.V. (coefficient of variation) are given for
yields at each location in 1980.
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 rela-
tive performance of hybrids.
A composite rating system was used to determine the list of accep-
table hybrids. The 3-year regional average grain yield of a hybrid was
used as a base point. Then,the composite score was obtained by subtract-
ing weighted values for lodging, quality, and ear height from this yield.
The value subtracted for each characteristic was proportional to the numer-
ical values shown for the characteristics in tables 3, 7, and 11.
All acceptable hybrids are not equal in performance. Some are out-
standing in one or more characteristics. Others may not be outstanding
in any one characteristic, but possess a satisfactory combination of
4
characters. All infonnation should be carefully considered when select-
ing a hybrid,

VIRAL DISEASE REACTIONS OF SOME HYBRIDS IN 1980
Robert T. Gudauskas
Department of Botany, Plant Pathology,
and Microbiology
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 (MVM) caused by the maize dwarf mosaic virus (MDMV).
Discovery of ~MD in the State dates back to the early 1960's, while MCD
has been recognized only since 1973. Both diseases probably occur through-
out 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 NEM-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 iv W is carried by some aphids.
Both viruses have similar host ranges among a variety of wild and culti-
vated grasses. Johnsongrass is an important overseason or reservoir host
for the viruses, and MCD and N M 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 of MCD and MI. Commercial and experimental hybrids are
evaluated yearly to identify resistant hybrids or promising sources of
resistance to the diseases. Results of evaluations of some :corrercial
hybrids during 1980 are summarized in this report.
37
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 4 were counted and data are reported as percent incidence
of viral diseases for each hybrid.
RESULTS
Evaluations for viral diseases in the hybrid test on the Black Belt
Substation are given in table 22. Data given are total incidences of
viral diseases. No attempt was made to separate MCD and MM at the time
of rating. However, MCD was clearly the predominant disease throughout
the test. Tests on the Piedmont, Tennessee Valley, Sand Mountain, and
Upper Coastal Plain substations were also examined, but disease inci-
dence was insignificant.
The incidence of viral diseases ranged from 0-35% among the hybrids
in the test and averaged 11.3% for the entire test. No symptoms of
virus disease were found in Jacques JX227 and Paymaster UC9792, and
disease incidence was less than 5% in several other hybrids.
Hybrids showing relatively greater resistance or tolerance were
apparent. Under conditions of higher or lower incidence of viral
diseases 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 occur, along with consideration
of yield and other characteristics given elsewihere in this report.
