Abstract
The effect of the high-oleate trait of peanut on aflatoxin production was tested by comparing
normal oleic lines with high-oleic backcross-derived lines. Seeds were blanched, quartered, and
inoculated with Aspergillus flavus conidia, placed on moistened filter paper in petri dishes, and
incubated for 8 days. In one experiment, dishes were stacked in plastic bags in a Latin square
design with bags and positions in stacks as blocking variables. High-oleic lines averaged nearly
twice as much aflatoxin as normal lines. Background genotype had no significant effect on
aflatoxin content, and interaction between background genotype and oleate level was not detected.
In a second experiment, dishes were arranged on plastic trays enclosed in plastic bags
and stacked with PVC spacers between trays. Fungal growth and aflatoxin production were
greater than in the first experiment. Background genotype, oleate level, and their interaction
were significant. The mean of high-oleic lines was almost twice that of normal lines, but the
magnitude of the difference varied with background genotype. Special care should be taken
with high-oleic lines to prevent growth of Aspergillus spp. and concomitant development of
aflatoxin contamination.
