Fourteen peanut genotypes (Arachis hypogaea) were evaluated for resistance to Aspergillus parasiticus infection in 1983 and 1984 in rain-shaded field microplots where water stress conditions were simulated, and in unshaded microplots under normal rainfall conditions. A brown color mutant of A. parasiticus (ATCC 24690) was grown on cracked corn and the colonized corn was spread on the soil in each microplot. Soil moisture and soil and air temperature were monitored. Infection of peanut pegs, pods, kernels and tap and fibrous roots was enhanced by low soil moisture. Infection of kernels differed among genotypes; all other tissues were found to be infected at moderate to high frequency and no genotype differences were observed.
Genotypes J-11 and Lampang were characterized as resistant to
