Performance of Corn Hybrids in Alabama, 1979
Cliff G. Currier1
/
Corn hybrids are evaluated annually at 12 locations in the regular
corn hybrid testing program of the Auburn University Agricultural 
Experiment
Station. Preliminary tests also are conducted at 5 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 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 hybrid tests were initiated
in 1979. Eight white corn hybrids were tested at one location in each region
in 1979.
Rainfall distribution was fair to good depending upon location during
the 1979 growing season. Excellent yields were obtained at Crossville,
Fairhope, and the irrigated test at Headland. All locations, except the
unirrigated test at Headland, had higher test averages than in 1978. Generally,
yield reduction was due to the lack of adequate rainfall during the period of
greatest need for moisture by the hybrids in the test. Data from Monroeville
Experiment Field were not reported due to low and erratic yields. Data from
Camp Hill were not reported due to large differences in plant population
in the plots.
Locations of the tests, cultural practices, and average plant populations
are shown in table 1. 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 42 inches depending on location. At Camp Hill, one-row
plots 40 feet long were used. At all other locations, two-row plots were
1'Research Associate, Department of Agronomy and Soils
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.
The seeding rate was 23,000 seeds per acre at each
location. The target plant population for the irrigated test at
Headland was 26,000 plants per acre, with a seeding rate of 29,700
seeds per acre. Most locations achieved the target 
plant
population.
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, earworn damage, size of
grain, and luster of grain were used in rating grain quality. Height of
ears was measured from the base of the ear to ground level. Husks
were rated according to tightness 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.
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
location, 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 irrigated hybrid test was moved from Camden
to Headland in 1979. Yields from this test were excellent. Results of
the irrigated corn hybrid test at Headland for 1 year are shown in
table 14. In 1979, this test was sprinkler irrigated on May 28, June 1,
6, 12, and 18. Approximately 5 inches of irrigation water was applied over
this period of time. Data from 1976, 1978, and 1979 tests at Marion Junction
are given and should be used to assist in comparing hybrids grown in that area.
Performance of corn hybrids at Marion Junction for 3, 2, and 1 years are
given in tables 15, 16, and 17 respectively, Yields and other characteristics
of white corn hybrids grown at Crossville, E. V. Smith Research Center (near
Shorter), and Headland are given in Table 18. Results of the preliminary
tests are given in tables 20-22.
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 Camp Hill are given in table 19.
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) and C.V. (coefficient of variation) are given for yields at
each location in 1979.
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
characters. All information should be carefully considered when selecting a
hybrid.

VIRAL DISEASE REACTIONS OF SOME HYBRIDS IN 1979
Robert T. Gudauskas
Department of Botany, Plant Pathology, and Microbiology
INTRODUCTION
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 MOM 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. MCOV
is transmitted by certain leafhoppers and MOMY 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 johnsongrass.
Use of resistant or tolerant corn hybrids presently is the most prac-
tical control for MCD and MOM. Commercial and experimental hybrids and
inbred lines are evaluated yearly to identify resistant hybrids of promising
33
34
sources of resistance to the diseases.. Results of evaluations of some
commercial hybrids during 1979 are summarized in this report.
PROCEDURE
Viral disease ratings were made on entries in the corn hybrid test
at the Piedmont Substation, Camp Hill. Plants showing symptoms of
MCD and/or MDM were counted and data are reported as percent incidence of
the diseases for each hybrid.
RESULTS
Evaluations for viral diseases in the hybrid test on the Piedmont
Substation are given in table 19. Tests on the Black Belt, Tennessee
Valley, Sand Mountain, and Upper Coastal substations were also examined
but disease incidence was insignificant.
With two exceptions, MCD and MDM were found in every hybrid in the
Piedmont test. Average incidents of MCD within all hybrids was 7.2% as
compared to 16.7% for MDM. Occurrence of both diseases in the same plant
was frequently observed.
Hybrids showing relatively greater resistance 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.
