Yields and Other Agronomic Characteristics of Cytoplasmically Pollen Sterile Corn Hybrids, Compared to Their Normal Counterparts1

  1. Donald N. Duvick2

Synopsis

Synopsis

Performance patterns of several corn hybrids were changed with respect to grain yield, barrenness, tillering and in one instance, root lodging when Texas (T) cytoplasm was substituted for the hybrids' normal cytoplasm. Grain yield and barrenness of another hybrid were affected when USDA (S) cytoplasm was substituted for its normal cytoplasm. The extent and direction of these induced changes were markedly affected by (1) the genotype and (2) the physical environment during the growing season.
