Accurate records are kept on Each new hybrid is planted in separate 
every step in DeKalb's exten- rows, and harvested individually. Accurate 
sive breeding program. yield comparisons are made by weighing. 
Out of perhaps 2,000 inbred and hybrid combinations, one out¬ 
standing corn variety may be discovered. First, the new variety must 
pass rigid tests on DeKalb's experimental farms. Next, it must prove 
itself adaptable to soils and growing conditions on hundreds of actual 
proving grounds. Finally, DeKalb puts out thousands of samples 
with farmers and accurately checks yields at harvest time. If the 
new variety measures up to DeKalb's high standards, it is given a 
permanent identifying number and put into commercial production.

DeKalb's research has produced 
many kernel textures ranging all 
the way from hard and smooth 
to soft, rough-dent types. As a 
result, farmers now may choose 
not only varieties adapted to their 
own growing conditions, but also 
the ear and kernel type best 
suited to their methods of feeding. 
Inbreds are planted in January 
on DeKalb's experimental farm 
near the Rio Grande River, in 
Texas -harvested in late May and 
flown by plane to corn-belt breed¬ 
ing plots in time to be planted 
that same spring. By so doing, 
DeKalb develops new inbred 
strains in less time which means 
a greater number of new varieties 
to suit a wider range of needs.
