VARIETIES
Open pollinated
The availability and performance of superior hybrids essentially have made the practical use of open-pollinated corns obsolete. Open pollinated corns often suffer from low yields and poor standability. Four open-pollinated varieties—Early Butter, Reids Yellow Dent, Golden Surprise, and Lancaster Surecrop—were evaluated in Pennsylvania Hybrid Corn Tests. Of 59 county tests, the average yield for the open-pollinated varieties was 82.9 bushels per acre with 29.4 percent down stalks. The average yield of the hybrids was 132.9 bushels per acre with 7.8 percent down stalks—a 50-bushel or 60 percent yield advantage.
