About a Week Earlier Than PIONEER 322 
Pioneer corn breeders are proud to offer Pioneer 353. It’s one of the very 
best all-around Northern corn belt hybrids selected from over 2,000 Pioneer 
experimental hybrids made and tested in northern Iowa, Minnesota, and South 
Dakota during the last seven years. 
COMBINES HIGH YIELD, STIFF STALKS, 
stronc Roots AND EARLY MATURITY 
Pioneer 353 produces extra high yields of sound corn in its adapted area, and stands up 
exceptionally well, having very stiff stalks, and strong roots. In the official 1940 Minnesota Corn 
Yield Trials, Pioneer 353 was the highest yielding corn in Group II (adapted corn) in Nobles, 
Mower, and Winona counties, and third in Group II in McLeod county. In Group I (earliest 
group), it was third in yield in Nicollet county and ranked fourth among 31 corns in Group I 
in Martin county. 
In the Martin County test field, some hybrids were reported as 100 per cent lodged. Pioneer 
353 ranked fifth among 61 hybrids tested for lodging resistance. Pioneer 353 made an equally 
good record for lodging resistance in the Nobles county field, ranking fourth among 58 hybrids.
