PERFORMANCE OF EXPERIMENTAL CORN HYBRIDS 
IN ILLINOIS, 1960 

By EARL R. LENG, R. J. LAMBERT, M. L. PEASLEY, 
G. L. Ross, and K. E. WILLIAMS* 

ONE OF THE OBJECTIVES OF CORN BREEDERS at the Illinois Agricul- 
tural Experiment Station is to develop improved corn inbreds 
and hybrids for use by seedsmen and farmers of the state. Such 
development requires considerable breeding work and adequate testing 
of performance at a number of locations and for a period of years. 
This bulletin summarizes results of experimental corn hybrid perform- 
ance trials conducted in 1960. The experimental corn hybrids tested 
were selected on the basis of their performance in preliminary tests or 
in advanced tests of previous years. 

In 1960 experimental corn hybrids were tested at twelve different 
locations in the state: Ashkum, Bowen, Brownstown, Carbondale, 
DeKalb, Galesburg, Greenfield, Peoria, Stanford, Urbana, Wolf Lake, 
and Woodstock. The maturity series tested at each location, the soil 
types, the distribution of rainfall during the growing season, dates of 
planting and harvesting, and planting rates per acre are given in 
Table 1. 

MATERIAL TESTED 

A total of 205 corn hybrids, consisting of 109 double crosses, 93 
three-way crosses, and 3 single crosses, were tested in advanced corn 
performance trials in 1960. Most of the hybrids tested were developed 
by corn breeders at the University of Illinois. 

Double crosses tested. Double crosses tested were divided into 
maturity groups, each consisting of a different set of 25 hybrids. The 
groups used were based on the AES (Agricultural Experiment Station) 
maturity series; the groups adapted to Illinois range in maturity from 
"600" in extreme northern Illinois to the "900" group in southern areas 
of the state. For testing purposes, hybrids comparable in maturity to 
those of the AES "800" series were divided into "800" and "850" series. 
The "800 series" hybrids were grown in north-central Illinois and the 
"850 series" in central Illinois. Illinois Station hybrids of comparable 
maturity rating are as follows: 600 series = Illinois 1555 A; 700 series 
= Illinois 3152; 800 series = Illinois 1421; 850 series = Illinois 1570; 
and 900 series = Illinois 1851.

[March, 



Three-way crosses tested. Three-way crosses are useful for evalu- 
ating the combining ability of an inbred line. Thirty-one inbreds 
crossed with three single-cross testers, (WF9 X Oh43), (WF9 X 
B37), and (B41 X Oh7A), were tested at Brownstown, DeKalb, and 
Urbana in 1959 and 1960. The test at Brownstown, however, was 
abandoned in 1960 because of poor stand, so 1959 and 1960 summaries 
are available only for DeKalb and Urbana.

1961] EXPERIMENTAL CORN HYBRIDS 5 

Performance trials of this type are necessary to properly evaluate 
improved corn inbreds. The performance of an inbred in a combina- 
tion with three different single-cross testers is a measure of the com- 
bining ability of the inbred line being tested. Tests at a number of 
locations and for several years more accurately measure combining 
ability than tests for only one year or at one location. 

Availability of material tested. A number of the Illinois Station 
corn hybrids listed in this report are not yet in commercial production. 
The Experiment Station release policy is to make available to the public 
seed of inbred lines that have demonstrated superior performance for 
desirable agronomic characters. Small amounts of seed (up to 100 
kernels) of released Illinois inbred lines are available for a nominal 
fee. Requests for seed of released Illinois inbred lines should be ad- 
dressed to the Department of Agronomy, University of Illinois, 
Urbana, Illinois. Station Bulletin 657 lists the Illinois inbred lines 
released up to and including 1960, and also presents data on some of 
their important agronomic characteristics. Seed of single crosses that 
are used as parents for some Illinois Station hybrids reported in this 
bulletin may be obtained from the Illinois Seed Producers Association, 
Champaign, Illinois. 

FIELD PROCEDURES AND ANALYSIS OF DATA 

Method of planting. All test locations except Carbondale were 
planted with a mounted four-row John Deere tractor planter, slightly 
modified for planting experimental plots. The Carbondale location was 
planted by hand. All locations were planted on land prepared in the 
normal manner for corn. Individual plots were one row 11 hills in 
length. Planting simulated "power check," with a variable number of 
kernels being dropped approximately each 20 inches, depending on the 
planting rate used. All plots were band-treated for weed control with 
Atrazine at a rate of 12 pounds per acre. The plots were not thinned. 

Method of harvest. All plots were harvested with a one-row Ford 
picker-sheller modified to harvest experimental plots. The shelled corn 
from each plot was bagged, weighed, and sampled for moisture using 
a Radson moisture meter. No adjustment was made for dropped ears 
or for ears on broken stalks that were not harvested. 

Field-plot design and analysis of data. The experimental designs 
used for all trials were lattice designs with 3 replications. All field data 
were recorded on mark-sense cards and processed with digital com- 
puters at the University of Illinois. 



6 BULLETIN No. 669 [March, 

MEASURING PERFORMANCE 

All hybrids tested were compared for grain yield, kernel moisture, 
erect plants at harvest, and stand. Data on other agronomic characters 
such as dropped ears, leaf blight reaction, stalk rot, and smutted plants 
were recorded when natural conditions permitted measuring true 
varietal differences. 

Yield of grain. Acre yields are reported as shelled corn containing 
15.5 percent moisture, the upper limit for No. 2 corn. 

Erect plants. A count of erect plants in each plot of an entry was 
taken at harvest time for each location. Only plants leaning at an angle 
of 45 or more or broken below the ear were considered lodged; all 
others were counted as erect. 

Stand. A count was made in late summer at all locations of the total 
number of plants in each plot of a hybrid. The percent stand was 
computed by comparing the actual number of plants in each plot with 
the number of kernels planted. Stand differences may have been caused 
by failure of seed to germinate or by disease, insect damage, cultivation 
injury, or other factors. 

TEST RESULTS 

Results from the tests are summarized in Tables 2 to 13. The fol- 
lowing facts should be considered when comparing the performance of 
hybrids in a test. 

1. Results covering two and three years at a location are more 
reliable than results for only one year. The performance of hybrids 
tested only in 1960 should not be used as a measure of their true ability 
since further testing will be necessary before valid conclusions can be 
drawn. This is true of all hybrids tested at Ashkum, Bowen, Carbon- 
dale, Galesburg, Greenfield, Stanford, Wolf Lake, and Woodstock. 
Results from these tests are not ranked by yield but are listed accord- 
ing to hybrid designation. Two- and three-year summaries are avail- 
able for Brownstown, DeKalb, Peoria, and Urbana, and entries are 
ranked according to yield in these summaries. 

2. Small differences between hybrids do not necessarily indicate that 
one hybrid is truly superior to another. Interpretation of the data and 
comparisons between hybrids are made more meaningful by use of cer- 
tain statistical procedures. One procedure used to compare the differ- 
ence between hybrids is the "Multiple Range Test." 1 Using this 

'DUNCAN, D. B. "Multiple Range and Multiple F Tests." Biometrics 11 (1) 
1-43, 1955. 



1961} EXPERIMENTAL CORN HYBRIDS 7 

statistical test, the difference necessary for significance between two or 
more hybrids can be calculated. Whenever the observed difference 
between two or more hybrids exceeds the amount calculated for that 
range, the two hybrids are significantly different. To find the difference 
necessary for significance the hybrids are first ranked according to 
performance for a particular character. Then the "number in range" 
can be computed by counting the hybrids to be compared and the 
number of hybrids falling between them in performance. For example, 
if hybrids A and E are to be compared and the rank in performance is 
A, B, C, D, E, the "number in range" would be 5. When the "number 
in range" has been determined, the corresponding "difference necessary 
for significance" can be read from the figures at the bottom of each 
table. If the observed difference exceeds the "difference necessary for 
significance," the performances of the hybrids are considered different.
