 Kentucky Hybrid Corn Performance Test
1978
By C. G. Poneleit and K. O. Evans
The objective of the Kentucky Hybrid Corn Performance
Test is to provide unbiased performance estimates of hybrid seed
corn sold in Kentucky. Every effort has been made to conduct the
test in an unbiased manner according to accepted agronomic prac- `
tices.
PRESENTATION OF DATA
Complete 1978 data are presented for the normal population
test at each location. Two—year and three—year averages for yield
are included in each of the single—location tables. Readers are
encouraged to consider these multiple year averages and the
averages over locations (Tables 10, 11, and 12) since these are
better estimates of a hybrid’s relative yield ability than data
gathered at one location in one year.
Comparisons between yields or other characters of any two
or more hybrids should be made only with data from one table at
a time. The testing procedures do not provide a suitable compari-
son between a hybrid grown at one location and population with
’ another hybrid grown at a different location and population.

 TESTING PROCEDURE _
SELECTION OF HYBRIDS
The hybrids chosen for testing are those most likely to be
available for sale in 1979. Seed of each commercial hybrid (Table
1) was obtained from the sponsoring company.
Those hybrids grown in the corn virus tests are indicated in
column 2 of Table 1. The hybrid corn companies were asked to
nominate those hybrids known to have virus resistance for inclu-
sion in the virus test.
LOCATION OF TESTS
The map on page 3 shows the location for each test. The
non-virus test sites were selected to represent different agro-
climatic areas of the state where corn is a major crop commodity.
The Henderson and Hodgenville sites are specifically for the
presence of corn virus in diverse areas of the state and should
represent differences in virus populations. The 1976 data for Table
13 are from the 1976 Russellville location.
CULTURAL PRACTICES
The secdbed at each location except Elizabethtown was
prepared by conventional tillage methods. Fertilizer was applied as ’ ’
indicated by soil tests. The test at Elizabethtown was planted in a
fescue sod using recommended no-tillage practices. All test areas
were treated with herbicide and supplemented by l)OS[—ClT1Cl`gCllCC
cultivation when necessary. Except for the virus tests, Furadan
was applied in the row at planting. Table 2 shows the specific
cultural treatment for each location.
EXPERIMENTAL DESIGN
Each hybrid was grown in three separate plots at each loca-
tion to sample uncontrollable variability of soil types, fertility,
and other factors. Annual mean yields presented in Tables 3
through l—l are the average of three replications at that test site
4

 while 2-year and 3-year means are averages of six and nine replica-
` tions, respectively. Means from the 1978 tests are from Random-
ized Complete Block analyses, while previous years’ means are
from analyses of lattice designs.
PLANTING
All plots were planted with a two-row, no-till planter modi-
fied for small plot work. The planter boxes were replaced by
special planting cones which allowed planting of a specified
number of kernels per plot. Each plot consisted of two rows 38
inches apart and 22 feet long. Each normal population, conven-
tional tillage test was planted at the rate of 22,000 kernels per
acre. The normal population, no-till test was planted at 25,000
` kernels per acre. Final stands were expected to be between 19,000
and 20,000 plants per acre if average stand losses occurred.
HARVESTING
All plots were harvested with a modified two-row self-
propelled corn combine. Both rows of each two-row plot were
picked, shelled, and the grain collected in a metal container. The
grain weight and moisture content of each plot were then
measured with a portable scale and moisture meter. Yields were
calculated and adjusted to No. 2 corn at 15.5% moisture. Dropped
ears were not gleaned from the plots. The number of plants were
recorded immediately prior to harvest.
CORN VIRUS
Two corn virus diseases occur in Kentucky: maize dwarf
mosaic virus (MDM) and maize chlorotic dwarf virus (MCD). Both
overwinter in johnsongrass and are usually present as a virus
complex. Preliminary laboratory tests of johnsongrass rhizomes
indicated the presence of MDM and MCD at the Henderson loca-
tion and MDM at the Hodgenville location. During the growing
season, symptoms of MDM and MCD appeared on plants at the
Henderson location but few plants had virus symptoms at the
Hodgenville location.
5

 Visual ratings of virus symptoms were made at the Henderson
location but not the Hodgenville location and are included with
yield and other data in Table 14. Even though the virus did little
apparent damage to the hybrids at the Hodgenville location the
yield data are presented in Table 13 and may be used to compare
the yield potential of these potentially virus-resistant hybrids A
under low-level virus conditions. The virus ratings in Table 14 are
on a 0 to 9 scale. A rating of 0 means that the plants showed no `*
virus symptoms while a rating of 9 means that nearly all plants had
very severe symptoms and would likely produce no grain. Inter-
mediate values represent degrees of virus resistance or suscepti-
bility.
Two virus-susceptible check hybrids were included in the
virus tests. Their average performance is listed in Tables 13 and 14
as Susceptible Cheeks.
NOTES ABOUT THE GROWING SEASON
MAYFIELD:
The Mayfield test was planted on April 28 and harvested on
September 26. Precipitation was above average for the first four
weeks after planting but severe shortages occurred during _]une and
july. Loss of herbicide activity because of the heavy, early rainfall,
drought during the pollination and grain filling period, and heavy _
European Corn Borer infestation contributed to the low yields at `
this location.
PRINCETON:
The Princeton test was planted on May 24 and harvested on
September 28. Except for August, precipitation was relatively
short throughout the growing season. Recorded precipitation
amounts from june through September were 1.21, 2.19,4.23 and
0.4 inches, respectively. Temperatures were relatively high; 23
days of greater than 95°F and four days of more than lOO°I·`.
Weed control was excellent and disease or insect problems were
minimal.
6

 HARTFORD:
, The Hartford test was planted on May 22 and harvested on
October 11. Precipitation amounts for May (22-31), june, july,
August, September and October (1-11) were 1.5, 2.0, 8.7, 4.8, 0.7,
and 1.3 inches, respectively. European Corn Borer and a late
season attack of southern leaf blight (H. maydzis) were observed,
but neither did major damage.
HENDERSON:
The Henderson test was planted on May 30 and harvested on
October 12. Precipitation was adequate during june and early july
but was deficient during the remainder of the growing season.
. High temperatures during the latter part of the growing season
may have affected yields. The plot area was cultivated once and
hand weeded twice to control the large amount of _]ohnsongrass
that was not eliminated by the herbicide treatment.
ELIZABETHTOWN:
The Elizabethtown test was planted no-till on April 17 and
harvested on October 2-4. Cool, dry weather immediately
following planting may have accentuated germination and seedling
emergence problems. Precipitation was adequate for the last half
of the growing season. Minor bird damage was observed but
* disease and insect problems were negligible.
FRANKLIN:
The Franklin test was planted on April 13 and harvested on
October 4 and 5. Precipitation was adequate until mid-july but
deficient thereafter. European Com Borer damage was significant
and caused substantial lodging.
QUICKSAND:
The Quicksand test was planted on May 19 and harvested on
~ October 19 and 20. Growing conditions were good throughout the
entire season. Disease and insect problems were minor although
virus diseases were observed late in the season.
7

 HODGENVILLE: A
The Hodgenville test was planted on june 2 and harvested on
October 25. Precipitation amounts forjune through October were
2.7, 2.2, 8.9, 1.4 and 8.2 inches, respectively. Some damage
caused by European Corn Borer was observed. Although this test
site was selected for the presence of com virus diseases and
infected Johnsongrass was present, development of virus
syrnp toms on the corn plants was minimal.
LEXINGTON:
The Lexington test was planted on May 20 and harvested on
October 16-18. Precipitation amounts for May (20-31),_]une,_]uly, ·
August, September and October (1-18) were 0.8, 2.4-, 4.7, 7.2, 0.9,
and 2.9 inches, respectively. Rain and wind caused heavy lodging
on july 31. Heavy European Corn Borer infestation caused
additional lodging.
