Seed il Pieked 
PIONEER hybrid seed corn picking 
starts early in the fall . . . usually about 
September 15th . . . long before the first 
damaging freeze occurs. 
Only female ears from the detasseled 
rows are picked for seed . . . the self- 
pollinated corn on male or pollen rows, 
harvested later, is never used as hybrid 
seed. 
During the busiest part of processing 
season, about 15,000 bushels of hybrid 
seed is picked and delivered daily to 
PIONEER corn plants. 
ABOVE—POLLEN (MALE) ROWS LEFT STANDING 
LEFT—SEED GOES DIRECTLY TO SORTING BINS 
To eliminate the dangers of heating, 
PIONEER hybrid seed corn is delivered 
to the processing plants on the same 
day it is picked. PIONEER takes every 
precaution to safeguard its customers 
against inferior seed corn . . . for only 
choice, quality seed produces higher 
yielding, money-making corn crops. 
ONLY DETASSELED (FEMALE) ROWS ARE HARVESTED
