PERFORMANCE OF CORN HYBRIDS IN ALABAMA, 1984
W. C. Johnson and Darrell Williams
INTRODUCTION
Corn hybrids are evaluated annually 
by the Alabama Agricultural
Experiment Station in the Regular Corn Hybrid Test and the Preliminary
Corn Test on a northern, central, and southern regional basis. The
Marion
Junction, or Black Belt Substation, corn test is used as the prairie
soil regional comparison. Entries in the preliminary tests are both
experimental and newly released hybrids. If a hybrid is outstanding in
the preliminary test, it is entered in the regular corn test the
following year. White and early corn hybrids are tested at one location
in each region. One regular and one white corn hybrid test are
irrigated at Headland in southern Alabama.
The locations and cultural practices for the tests are shown in
Table 1.
The tests were designed as 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 ranging from 20 to 30 feet
depending, again, on location. The target plant population for the
tests was 20,000 plants per acre with a seeding rate of 23,000 seeds per
acre. The irrigated tests at Headland were seeded at a rate of 30,000
plants per acre and thinned to 26,000.
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. The mid-silk data measured the number

of days from planting until one-half of the plants in the plots were
showing silks.
Bushel test weights are reported as regional averages from this
year's data. Grain and husk quality ratings are given as a regional
average of the 1984 tests. The ratings were based on a 1 = excellent to
a 5 = very poor system.
The corn hybrid tests are examined for disease incidence each year
by R.T. Gudauskas, Professor of Botany, Plant Pathology, and
Microbiology. When virus or other disease symptoms indicate crop
damage, disease ratings are compiled and published in this report.
Virus infection data from the test at Marion Junction are reported this
year.
To aid in determining real yield differences, a statistical
analysis of variance is performed on the data from each location. The
L.S.D. (least significant difference) and C.V. (coefficient of
variation) are given for each location's 1984 test. The difference in
yield of two hybrids must exceed the L.S.D. value for one hybrid to be
considered superior to the others in yield in that particular test. The
C.V. is a measure of the variability in an experiment. An increase in
its value indicates an increase in the unaccounted for variability.
Since the performance of hybrids varies with location and year,
long-term averages from several locations are more reliable than 1-year
performance. Three-year regional averages are considered a reliable
evaluation of the relative performance of hybrids.
A committee comprised of Department of Agronomy and Soils and
Alabama Cooperative Extension Service personnel involved in corn
research reviewed the past 3 years of corn hybrid test data to assemble
the list of acceptable hybrids on page 26.

The recommended hybrids 
are not all equal in 
performance. Some are
outstanding in one 
or more characteristics; 
while others may not 
be
obviously outstanding, 
they might possess 
a satisfactory combination 
of
all characteristics.

*1= EXECELLENT; 5= VERY POOR
VIRAL DISEASE 
REACTIONS OF SOME 
HYBRIDS IN 19842
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 some-
times difficult to distinguish. Generally, 
affected planti 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 the 
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 MOM incidence and damage
usually are high in corn fields that 
are heavily infested with johnson-
grass.
Use of resistant or tolerant corn 
hybrids and the control or
avoidance of johnsongrass infested 
areas are the most practical controls
for MCD and MDM. Commercial 
and experimental hybrids are evaluated
yearly to identify resistant hybrids 
or promising sources of resistance

of Botany, Plant Pathology,
and Microbiology.

to the diseases. Results of evaluations 
of some commercial hybrids during
1984 are summarized in this report.
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 MDM were counted and data 
are reported as percent incidence 
of the
diseases for each hybrid.
Results
At the Black Belt Substation, 
Table 9, incidence of MDM ranged 
from
0 to 28.2 percent among hybrids 
and averaged 4.8 percent for 
the entire
test; incidence of MCD ranged 
from 0 to 20.8 percent and 
averaged 8.1
percent for the test. DeKalb brand XL-72B showed no symptoms of either
disease, and incidence of either 
disease was less than 5 percent 
irfn at
least 27 other hybrids.
Hybrids showing relatively greater 
resistance or tolerance were
apparent. Under conditions of 
higher or lower incidence of 
viral disease,
hybrids would be expected to 
retain their relative ranking. 
When selecting
a hybrid, viral disease reactions 
whould be taken into account 
for areas
where the diseases 
are known or suspected 
to occur, along with 
the consi-
derations of yield and other 
characteristics given elsewhere 
in this report.
