SUPERIOR and U. S. ORIGINATED 
U. S.13 A PRIZE WINNER 
In 1989 and 1941 U. S. 13 was in the blue rib- 
bon class. In 1939 and 1941 it took practically 
all of the prizes at the International Livestock 
Exposition. It has an exceptionally fine pedi- 
gree of high producing inbred lines. It was de- 
veloped by the U. S. D. A. 
U. S. 18 is a leader in the heart of the corn 
belt. Record yields prove beyond a shadow of 
doubt that it is a front ranking Hybrid in any 
section where it is adapted. 
Tllinois and Iowa tests show it high in pro- 
duction on different types of soils. It made front 
ranking position on soils of high, medium and 
low productivity. We know of no finer Hybrid 
on rich land. It is a large, deep grained, single 
eared variety. Has a deep golden cclor. Well 
dented kernels, moderately rough. [ias strong 
stalks and roots. Ears hang on wel? although 
it is not difficult to shuck. This is really a 
show type corn. It is one of the softer Hy- 
brids. Popular with cattle feeders.

This is early maturing corn. Grow- 
ers in southern Wisconsin tell us 
Wis. 641 is going to be a leader with 
big corn growers. In 1944 the yields 
exceeded some of the highly adver- 
tised varieties selling for $2.00 to 
$3.00 bu. more money. One grower 
told us Wis. 641 matures under nor- 
mal conditions as early in southern 
Wisconsin, as other Hybrids matur- 
ing in 107 to 110 days. The husks 
tend to open and the ears dry out 
quickly, Is distinguished for long 
sound ears, easy husking and high 
yield. Is an excellent feeding and 
cribbing corn. Is grown just: over 
the line from Illinois. Wis. 641 is 
adapted for planting in southern 
one-fourth part of Wis., northern 
part of Illinois. Also southern Mich- 
igan, northern Indiana, northern 
part Ohio, northern half Pennsyl- 
vania and on east in some latitude. 
Try some of this champion yielder. 

U. S. 13 is adapted over a wide area. In 
Ohio, U. S..13 was the highest yielding Hybrid 
in official state tests in sections:9, 10, 11 and 
12, which are located in the southern half of 
that state. It yielded 101.9 bu. acre against 
80.7 for open pollinated. It also was top rank- 
ing in west central Illinois state test. It 
yielded 24 bushel per acre more than the aver- 
age open pollinated in the same test. 
In the southern half of Iowa in districts 7, 
8, 9, 10, 11 and 12, a chart, taken from 1939 
Iowa corn yield test bulletin shows following 
average yield per acre: U. §. 138, 89.42 bu., 
U. S. 44, 89.19 bu., Illinois 960, 87.29 bu., Iowa 
Supercorn 119H, 87.21 bu., DeKalb 816, 85.87

An Outstanding Hybrid 
for Large Yields 
About 105 to 110 Day Corn 
ae a This variety was originated by the 
Iowa Experiment Station. Is similar 
to the Iowa 939. Is medium early. 
Some call it early. Has three of the 
same inbreds. The other inbred 
makes Iowa 306 an improvement over 
the Iowa 939 which has been a pop- 
ular Hybrid for the past 6 years from 
Iowa to Pennsylvania. Joe Robinson 
of Iowa Exp. Station in charge of 
Hybrid Corn experiments, Hybrid 
Corn inspection for the state, reports 
Iowa 306 is an improvement over 
Iowa 939. It does not have ear drop- 
page like many Hybrids. 
It is a top yielder. Does well on 
different types of soil. Is a softer 
corn than many-Hybrids. Has nice 
shaped ear. Kernels have slight red- 
dish cast on the side. Adapted to 
northern Illinois and Indiana and as 
far south as south central IIl., Ind., 
Ohio and other states on east. 
Price: Flat Grains $7.00 bu.; 
Round Grains $5.25 bu.
