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 15 and 15 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 1998, the late maturity test compared 30 white hybrids submitted by 12 commercial seed producers and the University of Tennessee, and the early test included 33 white hybrids from 13 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. Stewart's wilt reactions were observed at the University of Illinois. Kernel quality evaluation was don 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 1998 Late White Food Corn Performance Test included 30 white hybrids and three yellow hybrid checks submitted by 12 commercial seed producers and the University of Tennessee. Fifteen white hybrids were new to the test in 1998. Fifteen locations were plante in the agronomic evaluation. Three white hybrids and one yellow check hybrid yielded significantly more than the mean for all entries (155.6 bu/a): Pioneer Brand 3203W (171.9 bu/a), Pioneer Brand X1167BW (171.0 bu/a), Wilson E8051 (170.1 bu/a), and the yellow check Pioneer Brand 3245 (169.5 bu/a). Other hybrids that did not differ significantly from the top-yielding hybrid in the test included Pioneer Brand X1177PW (167.0 bu/a), Whisnand 50AW (166.4 bu/a), Garst N6278W (164.0 bu/a), Novartis N71-T7 (163.4 bu/a), Zimmerman Z64W (162.0 bu/a), Whisnand 51AW (160.4 bu/a), IFSI 95-1 (158.7 bu/a), and IFSI 98-1 (158.4 bu/a). The 1998 Early White Food Corn Performance Test included 32 white hybrids and two yellow hybrid checks submitted by 13 commercial seed producers. Twelve white hybrids were new to the test in 1997. Fifteen total locations were planted in the agronomic evaluation. Three white hybrids yielded significantly more than the average entry: Pioneer Brand X1127FW (204.6 bu/a), Wilson E8051 (192.3 bu/a), and Pioneer Brand X1127DW (188.7 bu/a). Pioneer Brand X1127FW was also significantly higher yielding than any other entry, except for Wilson E8051.
