Campbell, K. W., and White, D. G. 1995. Evaluation of corn genotypes for resistance to Aspergillus ear rot, kernel infection, and aflatoxin production. Plant Dis. 79:1039-1045. Resistance of corn (Zea mays L.) hybrids and inbreds to ear rot, kernel infection, and aflatoxin contamination caused by Aspergillus flavus was evaluated following inoculation. Thirty-five F 1 hybrids from crosses of selected inbreds with the susceptible inbreds B73 and/or Mo17 were evaluated for 3 years in Illinois. Fifteen of the F 1 hybrids also were evaluated in Mississippi. Resistant and susceptible inbreds per se also were evaluated for 2 years in Illinois. Inbreds Tex6, Y7, and Mp420, and the F 1 hybrids with these inbreds, consistently had the greatest resistance to Aspergillus ear rot, kernel infection, and aflatoxin production in the Illinois environment. Grain of the F 1 hybrids with these inbreds also had less aflatoxin in Mississippi. Pearson and Spearman rank correlation coefficients indicated that Aspergillus ear rot ratings provided a more accurate estimate of aflatoxin contamination of grain than did kernel infection. From evaluations of the F 1 hybrids and the inbred parents per se, inbreds were identified that may contain alleles for resistance not found in B73 and/or Mo17.
