Original 
Average of pure lines .... 
'Data for pure line parents compiled from Table 14 by including each in the average as often as it occurs in the hybrids. 
The F> hybrids were compared directly with the original corn, and their yields are here corrected to check plat yields, to be comparable with 
the yield of the other corn.
