PERFORMANCE OF CORN HYBRIDS IN AIABAMA, 1988
D.L. Thurlow and W.C. Johnson
1
INTRODUrITON
Corn hybrids are evaluated annually by the Alabama Agricultural
Experiment Station in the Regular Corn Hybrid Test and the Preliminary Corn
Hybrid 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.
Corn hybrids were evaluated for maturity and shuck quality at Tallassee using
all 149 of the 1988 entries in the Alabama test; the number of days to silking
and shuck quality ratings are reported in table 19.
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 30 to 36 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 25,000.
iRespectively, Associate Professor and Professor of Agronomy and
Soils.

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.
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 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
variability.
The corn hybrid tests are examined for disease incidence each 
year by
R.T. Gudauskas, Professor of Plant Pathology. When virus 
or other disease
symptoms indicate crop damage, disease ratings are compiled and 
published in
this report (page 17). Virus infection data from the test at Marion 
Junction
are reported this year, table 9.
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.
The irrigation test at Headland had 12.5 inches of water applied in 10
applications during May and June to supplement the 3.8 inches of 
rainfall.
The early corn test at Fairhope was not harvested because of only 
0.4 inch of
rainfall from April 20 through June 2. This was during the tasseling 
and
silking of the hybrids in the early test. The corn yields in north 
Alabama
-6-
locations were also poor due to an extended drought in May, June, and 
July.
The test at Winfield was not harvested and the Belle Mina 
and Crossville tests
were lower than normal.
A committee camprised 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 pages 35-37.
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 REACIONS OF SCOME HYBRIDS IN 19882
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 (MIM), caused by the maize dwarf mosaic virus (MEW~).
Discovery of MIDI in the State dates back to the early 1960's, while MCD has
been recognized 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.
Syrrptoms of the two diseases are similar in appearance 
and srmetimes
difficult to distinguish. Generally, affected plants are chlorotic or
discolored and may be stunted. Leaves of MEM diseased plants show an
irregular, light and dark green mosaic or mottle; the initial synptom 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 MEMV 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 MM 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 control for MCD and MDM.
Commercial and experimental hybrids are evaluated yearly to identify resistant
hybrids or promising sources of resistance to the diseases. Results of
evaluations of some commercial hybrids during 1988 are surarized in this
report.

Procedure
Viral disease ratings were made on entries in the 
corn hybrid test at the
Black Belt Substation, Marion Junction, and the Upper 
Coastal Plain
Substation, Winfield. Plants showing symptoms 
of MCD and/or MEM were counted,
and data are reported as percent incidence of 
the diseases for each hybrid.
Results
In the test of 38 hybrids at the Black 
Belt Substation, incidence of MCD
ranged from 0 to 9.1 percent among hybrids 
and averaged 1.3 percent for the
test; incidence of M[M ranged from 0 to 7.7 
percent and averaged 0.8 percent
for the test, table 9. Twenty-two hybrids 
showed no symptoms of either
disease. Levels of both diseases appeared 
to be much higher in a test of 48
hybrids at the Upper Coastal Plain Substation. 
However, drought effects
confounded symptom expression by the plants and 
precluded accurate estimates
of viral disease incidence at this location.
Hybrids showing relatively greater resistance 
or tolerance were apparent
at both locations. 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 the
considerations of yield and other characteristics 
given elsewhere in this
report.
