The hybrids consisted of two groups, an early group and a late group. The performance of experimental single cross corn hybrids is of considerable interest to individuals and companies interested in developing commercial hybrids. The data presented was believed to be of use to seedsmen and plant breeders interested in development of various types of hybrids adapted to North Dakota or areas with comparable environmental conditions, and of general interest to corn grain producers.North Dakota State UniversityArticle
