Seed producers, corn millers, and farmers need agronomic performance data to select white food-grade corn hybrids adapted for growing in specific regions of the United States. Smaller seed companies have benefitted by having their products tested in a much wider area than could be accomplished by the company itself. Late maturity, white food-grade corn performance and grain quality testing has been conducted from 1977 to the present. During 25 years of testing late maturity germplasm, 704 hybrids from public and private sources have been evaluated. Hybrids have been submitted for evaluation by two universities and 54 private companies. For 2001, 10 of 22 entries are new to the test. Early maturity, white food-grade performance and grain quality testing has been done since 1984. During 18 years of testing, 380 hybrids from public and private sources have been evaluated. Hybrids have been submitted for evaluation by three universities and 46 private companies. For 2001, 9 of 21 entries are new to the test. Data on European corn borer tolerance and Stewart's wilt susceptibility are obtained for both tests. Grain quality data provided by the Illinois Crop Improvement Association include test weight, 100 kernel weight, kernel density, kernel size, percentage thins, and percentage horny endosperm. Testing is supported by the North American Millers' Association and participating seed companies.
