A UNIFORM HYBRID 
for the Northern Corn Belt 
YIELD RECORDS OF PIONEER 370 
IN OFFICIAL 1940 STATE 
YIELD TESTS 
MINNESOTA 
In the official 1940 Minnesota Corn Yield Trials, con- 
ducted by the University of Minnesota, Pioneer 370 
was the highest yielding corn in Group I (Earliest 
Group) in both Nicollet and Winona counties. It was 
the highest yielding corn in Group II (Adapted corn) 
in Lincoln county, and was outyielded in Group II in 
Mower county only by Pioneer 353. Pioneer 370 
ranked very high in lodging resistance. 
MICHIGAN 
In the official 1940 Michigan Corn Yield Tests, con- 
ducted by Michigan State College, Pioneer 370 was 
first in yield in two of the seven test fields. No other 
hybrid had more than one first place position. 
ILLINOIS 
Among 60 hybrids entered in the Northeastern dis- 
trict of the official 1940 Illinois Corn Performance Test, 
Pioneer 370 placed third in earliness and yielded five 
bushels per acre more corn than the average of all 
entries.

@ UNIFORM EAR APPEARANCE 
Beautiful in the Field and Crib 
As you look down the rows in a field of Pioneer 
370, every ear is hanging at the same height, every 
plant looks like a twin to the one just beside it. 
When you pick the ears, they all look alike. A 
growing field of Pioneer 370 or a crib of Pioneer 
370 ears are both beautiful to see. You practically 
never find an ear that has dropped off the stalk, 
and you will like the way Pioneer 370 picks by 
hand. 
There is some tendency for a few of the stalks 
to have two ears instead of one. This may help 
account for its excellent yield record. Pioneer 370 
is only fair for drought resistance, and the ears run 
a little smooth and hard. 
leaves Stay Green While Corn Dents 
The leaves and stalk on this hybrid stay green 
in the fall while the ear ripens. You will be sur- 
prised to find the ear well dented while the husks 
are still green. 
A New tybrid That's Difficult to Produce 
Pioneer 370 gives you outstanding uniformity be- 
cause it is a three-way cross. It is more difficult 
and more expensive to produce than a four-way 
hybrid. Its yield is unusually high considering 
that it matures about ten days earlier than Pioneer 
322 and only slightly later than Pioneer 355.
