Nine maize hybrids from the 1994 crop, representing the range of hybrids grown in the U.S. central corn belt, were harvested at high (33–35%) and low (21–22%) moisture contents and laboratory dried at either ambient temperature (about 25°C) or 110°C. Similarly, nine maize hybrids from the 1995 crop were harvested at two different moisture contents and dried using either ambient temperature or 80°C. Both sets of samples were wet‐milled using a 100 g laboratory procedure. Significant differences were observed between hybrids as to the effect of drying air temperature and harvest moisture content on wet‐milling yields. Eight of the 9 hybrids dried at 110°C and harvested at high moisture contents showed significantly lower starch yields (by 7.2–15.1%) when compared to starch yields of the same hybrids dried at 110°C and harvested at low moisture contents. Results also indicated that there is a hybrid‐dependent effect of high‐temperature drying and harvest moisture content at 80°C drying air temperature. Starch yields of some hybrids harvested at low moisture contents are negatively affected if dried at 80°C. However, there were mixed results on starch yields if the hybrids were harvested at high moisture contents and dried at 80°C.
