Abstract
Methods of evaluating corn (Zea mays) stalk quality at or near anthesis and stalk rot susceptibility following inoculation were examined for 3 yr to identify those most effective in predicting premature death of plants and stalk lodging in multiple environments. Stalk quality measurements, including rind puncture, rind thickness, stalk push test, pith density or pith moisture, and susceptibility to the stalk rotting fungi Stenocarpella maydis and Colletotrichum graminicola, were determined on eight single-cross hybrids grown in Urbana, Illinois. Data on premature death of plants and lodging were collected from the same hybrids grown near Urbana in 1984 and at 16 locations throughout the midwestern United States in 1985 and 1986 [...]
