The characteristics of the hybrids listed above are based on comparisons with the average Pioneer hybrid—not on com- 
parisons with the open-pollinated corn or competitive hybrids. For instance, where a hybrid rates ‘Fair’ for “Stiffness 
of Stalk’ in these tables, it would actually rate “Very Stiff” if compared under open-pollinated standards.
