Interpretive Summary: Seed producers, white corn millers, and farmers need agronomic performance data to select white seeded corn hybrids adapted for growing in specific regions in the United States. The national performance tests of white hybrids included germplasm in late and early maturity groups and was planted at 14 and 11 locations, respectively. Smaller seed companies benefitted by having their products tested in a much wider area than could be accomplished by the company itself. In 1996, the late maturity test compared 43 white hybrids submitted by 17 producers and the early test included 58 white hybrids from 21 producers. Significant performance differences were found among the entries in both tests for yield and all agronomic traits measured. Kernel quality observations were made by the Illinois Crop Improvement Association. These observations included the quality traits of test weight, kernel weight, kernel size, thins, density, and percentage horny endosperm. A report was published and distributed to the participating state experiment stations, seedsmen, and corn millers and processors.

Technical Abstract: Seed producers, white corn millers, and farmers need agronomic performance data to select white seeded corn hybrids adapted for growing in specific regions in the United States. The 1996 White Food Corn Performance Test included 43 white hybrids, one white and three yellow hybrid checks submitted by 17 seed producers. Fourteen locations were planted in the agronomic evaluation. The overall average for 13 locations with acceptable data was 159.6 bu/a compared to 137.9 bu/a in 1995. Two white hybrids and one yellow check yielded significantly more than the mean for all entries (159.6 bu/a): yellow check Pioneer Brand 3245 (182.4 bu/a), Pioneer Brand 3203W (176.7 bu/a), and Pioneer Brand X1155FW (176.5 bu/a). Zimmerman Z62W (171.3 bu/a), IFSI 90-1 (169.1 bu/a), and Zimmerman Z64W (168.8 bu/a) did not differ significantly from the top-yielding hybrid in the test. The 1995 Early White Food Corn Performance Test included 58 white hybrids and two yellow hybrid checks with entries submitted by 21 seed producers. Eleven locations were planted with 10 of those being in the northern part of the Corn Belt. The overall average for eight northern locations with acceptable data was 142.5 bu/a, up slightly from 133.3 bu/a in 1995. No hybrid was significantly higher yielding that the mean of all hybrids. Twenty-five white hybrids and the two yellow checks could not be differentiated (yielded 142.3 bu/a or more) from the top yielding hybrid: Pioneer Brand X1155FW (157.5 bu/a). Kernel quality observations were made by the Illinois Crop Improvement Association. These observations included test weight, kernel weight, kernel size, thins, density, and percentage horny endosperm.
