PERFORMANCE OF CORN HYBRIDS IN ALABAMA, 1983
W. C. Johnson and Darrell Williams1
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 north, centra.1, and southern regional basis. The Marion
Junction, or Bl1ack 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 into the regular corn test the
following year. White 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 20-30 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

Soils.

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. All test weight values were adjusted to 15.5 percent
moisture to make comparisons easier.
The corn hybrid tests are examined for disease incidence each year
by Dr. R. T. Gudauskas, Department 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 arereported 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 1983 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 composite rating system was used to assemble a list of acceptable
hybrids. The 3-year regional average grain yield was used as a base
point. The composite score was obtained by subtracting weighted values
for lodging, quality, and ear height from the yield.

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.

VIRAL DISEASE REACTIONS 
OF SOME HYBRIDS IN 
19832
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 (MOM), 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 discoloredand may 
be stunted. Leaves of MDM-diseased
plants show an irregular, light and dark 
green mosaic ormottle; 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 MDM incidence and damage
usually are.high in corn fields that are heavily infested with
johnsongrass.
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

Pathology, and Microbiology.

to the diseases. Results of evaluations of some commercial hybrids
during 1983 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 30), incidence of MDM ranged
from 0-16 percent among hybrids and averaged 4.9 percent for the entire
test; incidence of MCD ranged from 0-14 percent and averaged 3.6 percent
for the test. McCurdy brands 81-34 and 7978, and Northrup King brand
PX95 showed no symptoms of either disease, and incidence of either
disease was less than 5 percent in at least 11 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 should be taken into
account for areas where the diseases are known or suspected to occur,
along with considerations of yield and other characteristics given else-
where in 
this report.
