Taking all of the data into consideration, it may be con- 
cluded that no material increase in weight results from fertiliz- 
ing a heterozygous kernel — as in an ordinary dent variety — with 
foreign pollen. On the other hand, altho there is a considerable 
variation between different strains, an approximate average 
increase in kernel weight of about ten per cent may be expected 
from fertilizing homozygous (pure line) kernels with foreign 
dent pollen.
