IMPORTANT 
O The iigures under "Yield", "Moisture", "Ear Height", "Root 
Lodging", and "Stalks Standing", are given in percentages oi 
Pioneer 322, in North Central Iowa, and Pioneer 307 in the Southern 
half of Iowa. Both these hybrids are assumed to be 100%. Under 
"Yield’' and "Stalks Standing", those hybrids whose percentages 
are higher than 100% have a higher yield record and have more 
standing stalks than Pioneer 322 in North Central Iowa, and 
Pioneer 307 in the Southern half of Iowa. 
Under "Moisture", those hybrids above 100% are later matur¬ 
ing than Pioneer 322 in North Central Iowa and 307 in the 
Southern half of Iowa. Under "Ear Height", and "Root Lodging", 
those hybrids below 100% have a lower ear height and less root 
lodging than Pioneer 322 and 307.
