A study was made to determine the effect of foreign or unrelated pollen on the yield of corn (Zea mays L.) when a difference either in endosperm type of in heterozygosity is involved. The problem has been attacked from the standpoint of acre yields, individual plant yields, and the differences in weight between pure and hybrid kernels on the same ear.

To study the differences of endosperm composition on yield, a late commercial strain of Stowell’s Evergreen sweet corn (su su) was secured. It was pollinated by ordinary field-run Hogue Yellow dent corn (Su Su) frown at the Nebraska Experiment Station for several years. In the starchy types, two inbred strains and one hybrid strain were used as female or pistillate parents and Hogue Yellow dent again as the foreign pollen parent.
