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 plante 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 2000, the late maturity test compared 23 white hybrids submitted by eight commercial seed producers, and the early test included 2 white hybrids from eight commercial seed producers. Significant performanc differences were found among the entries in both tests for yield and all agronomic traits measured. First- and second-generation European corn bore data were observed at Columbia and Marshall, MO. Corn earworm damage and mold occurrence were obtained from Lubbock, TX, and moisture stress respons swere observed at Halfway, TX. Stewart's wilt reactions were observed at t University of Illinois, and Gibberella ear rot was evaluated at Ottawa and Ridgetown, Ontario, in the early maturity test. Kernel quality evaluations were 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 2000 Late White Food Corn Performance Te included 23 white hybrids and two yellow hybrid checks submitted by eight commercial seed producers. Five white hybrids were new to the test in 2000 0Fourteen locations were planted in the agronomic evaluation. Four white hybrids yielded significantly more than the mean for all entries (159.5 bu/a): Pioneer Brand 32K72 (176.0 bu/a), Pioneer Brand 33T17 (174.2 bu/a), Zimmerman 1851W (174.2 bu/a), and Pioneer Brand 32Y52 (172.7 bu/a). An additional three white hybrids did not differ significantly from the top- yielding hybrid: Vineyard Vx4359W (170.1 bu/a), Zimmerman N71-T7 (167.7 bu/a), and Vineyard V433W (166.9 bu/a). The 2000 Early White Food Corn Performance Test included 24 white hybrids and two yellow hybrid checks submitted by eight commercial seed producers. Six white hybrids were new the test in 2000. Fourteen total locations were planted in the agronomic evaluation. The average yield from 12 Corn Belt locations was 145.6 bu/a. Only one white hybrid yielded significantly more than the average entry: Pioneer Brand 32K72 (165.3 bu/a). Not differing significantly from the highest-yielding hybrid were Pioneer Brand X1128BW (157.8 bu/a), Pioneer Brand 32Y52 (157.4 bu/a), Zimmerman N71-T7 (156.6 bu/a), Pioneer Brand 33T1 (156.2 bu/a), Vineyard Vx4359W (154.6 bu/a), Asgrow RX776W (152.5 bu/a), Vineyard Vx4319W (152.5 bu/a), Zimmerman 1790W (152.1 bu/a), Vineyard V433W (150.6 bu/a), and Pioneer Brand 34P93 (150.6 bu/a).
