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 locations each. Smaller seed companies benefitted by having their products tested in a much wider area than could be accomplished by the company itself. In 1999, the late maturity test compared 27 white hybrids submitted by 12 commercial seed producers and the University of Tennessee, and the early test included 26 white hybrids from 12 commercial seed producers. Significant performance differences were found among the entries in both tests for yield and all agronomic traits measured. First and second generation European corn borer data were observed at Columbia and Grand Pass, MO. Corn earworm damage, mold occurrence, and moisture stress responses were obtained from Lubbock, TX Stewart's wilt reactions were observed at the University of Illinois. Kernel quality evaluation was done by the Illinois Crop Improvement Association. These 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 1999 Late White Food Corn Performance Test included 27 white hybrids and three yellow hybrid checks submitted by 12 commercial seed producers and the University of Tennessee. Nine white hybrids were new to the test in 1999. Fourteen locations were planted in the agronomic evaluation. Two white hybrids and one yellow check hybrid yielded significantly more than the mean for all entries (136.9 bu/a): Pioneer Brand X1138AW (159.4 bu/a), the yellow check Pioneer Brand 3245 (153.1 bu/a), and Zimmerman 1851W (150.3 bu/a). One other hybrid did not differ significantly from the top- yielding hybrid in the test: Pioneer Brand 32K72 (148.2 bu/a). The 1999 Early White Food Corn Performance Test included 26 white hybrids and two yellow hybrid checks submitted by 12 commercial seed producers. Five white hybrids were new to the test in 1999. Fourteen total loca- tions were planted in the agronomic evaluation. The average yield from 10 Corn Belt locations was 156.4 bu/a. Two white hybrids yielded significantly more than the average entry: Pioneer Brand X1138AW (174.7 bu/a) and Vineyard V433W (172.5 bu/a). Not differing significantly from the highest-yielding hybrid were Zimmerman 1790W (165.8 bu/a), Pioneer Brand 34P93 (165.1 bu/a), Pioneer Brand 32Y52 (164.4 bu/a), Pioneer Brand 32K72 (164.0 bu/a), Zimmerman 1851W (163.7 bu/a), Zimmerman N71-T7 (161.3 bu/a), IFSI 95-2 (161.2 bu/a), Whisnand 50AW (161.2 bu/a), and Asgrow RX776W (159.9 bu/a).
