Certification Is Proof Of Larger Yield 
U.S. 
3 A 
It has an exceptionally fine pedigree of high produc¬ 
ing inbred lines. 
It is a big eared variety. Fields in 1939 produced 
the largest ears of any Hybrid we have ever seen. 
It is a large single eared type. 
Illinois tests showed it high in production 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 not an early variety but a big eared type. 
It is not a flinty corn and has good feeding value. 
As more of the seed becomes available and its great 
qualities better known, it should undoubtedly be¬ 
come an outstanding leader in popularity in the 
sections to which it is adapted. 
U. S. 13 should not be confused with Iowa 13. It is 
an entirely different corn with an almost totally different 
pedigree. The ears are somewhat smooth but deep ker- 
neled and have a bright orange tinge. It responds to 
good soil fertility. U. S. 13 is resistant to bacterial wilt. 
The stalks are strong and grow to medium height. 
U. S. 13 is one of the newer Hybrids, but has been 
making outstanding records. The lines Hy and L 317 
which are two of the inbreds in U. S. 13 are judged by 
many as the best inbreds developed so far. 
There are a few independent growers who apparently 
are marketing this line under private brands and these 
have shown top rank rating in Indiana and Missouri 
tests. In Ohio, the U. S. 13 was the highest yielding 
Hybrid in official State tests in sections 9, 10, 11 and 12, 
which comprise the southern one-third of that State. It 
also was top ranking in west central Illinois State test. 
It yielded 24 bushel per acre more than the average open 
pollinated in the same test.

Certified and 
State Originated Hybrid 
This Hybrid Combination (Ax90) (WF9 x 
Hy) is called Indiana 425 in that State. It 
is significant that both Illinois and Indiana 
are using the same variety. The inbred lines 
are all good ones. This is a little later than 
Wisconsin 570 described in the opposite 
column. In the Northern Illinois test for an 
average of three years, 1936, ’37 and '38, 
this was the highest yielding state originated 
Hybrid. Its time-tested record means some¬ 
thing. 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 locations in a total 
of 15 experiments at 13 locations. Produces 
a good sized ear. 
We suggest this for sections south of the 
northern tier of counties in Illinois, but 
away from Lake Michigan about 30 or 40 
miles. Exceptionally good in north central 
Illinois, Indiana, Iowa and in similar cli¬ 
mates. We are sure you will want to con¬ 
tinue with Illinois 751 once you start grow¬ 
ing it.

A State Originated Hybrid 
of Medium Maturity 
It was originated by the Iowa 
Experiment Station. Is widely 
grown in that state and in Illinois, 
Indiana, Ohio and on East. Has 
proven very popular in north cen¬ 
tral section of Ohio. 
In Illinois, the Iowa 939 Hybrid 
established yields in the north cen¬ 
tral part of the sta^e of 107.3 bushels 
total yield per acre at one station. 
It Showed higher resistance against 
lodging in all tests. Has shown as 
high as 45% increase in yield over 
average open pollinated in central 
Iowa. 
Has nice shaped ears. Kernels 
have a slight reddish cast on the 
side. A softer corn than most Hy¬ 
brids. Fine feeding quality. Adapted 
for northern Illinois with the excep¬ 
tion of the top tier counties. Also 
same latitude in Indiana and north 
central Ohio. We have many testi¬ 
monials from customers who planted 
Iowa 939 last year. We have the 
genuine State Certified stock and we 
recommend it highly.
