SUPERIOR and U. S. ORIGINATED 
U. S. 13 A PRIZE WINNER 
In 1939 and 1941 U. S. 13 was in the blue rib- 
bon class. In 19389 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. 13 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. 
Illinois 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 color. Well 
dented kernels, moderately rough. Has strong 
stalks and roots. Ears hang on well 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, 
State Originated 
MEDIUM SOFT HYBRID 
109 to 113 Day 
It’s medium early. Was originated by the 
state. This Hybrid combination (Ax90) 
(WF9xHy) is known as Indiana 425 in In- 
diana. The inbred lines are all good ones. 
751 is a little later than Wisconsin 
570 described on opposite page. In a test 
made in northern part of Illinois in 1936, 
1937 and 1938, for .an average of three 
years, this was the highest yielding state 
originated Hybrid Corn. A state test made 
at Arlington Heights, Ill., in 1939, Illinois 
751 had a higher yield than other Hybrids. 
It beat other highly advertised Hybrids sold 
by Agents for $7.00 to $7.50 per bushel. In 
Indiana this same Hybrid, under the name 
Indiana 425, for the average of two years, 
1937-38, was the highest in yield of all 
Indiana Hybrids in all loeations in a total 
of 15 experiments at 13 locations. Illinois 
751 produces a large sized well filled ear. 
We suggest this Hybrid for the northern 
one-third part of Illinois, except in counties 
near Lake Michigan. The northern half of 
Indiana and Ohio, and in similar latitudes. 
Try Illinois 751 this year and you will plant 
again next year.

U. S. 13 is, adapted over a wide area. In 
Ohio, U. S. 15 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.

An Outstanding Hybrid 
for Large Yields 
About 105 to 110 Day Corn 
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 Tllinois and Indiana and as 
far south as south central Ill., Ind., 
Ohio and other states on east.
