Abstract: Fungi in the genus Aspergillus produce aflatoxins which are a group of toxic secondary metabolites. Fungal invasion of peanut seed and subsequent aflatoxin production can occur before or during harvest as well as during storage. Because storage proteins comprise a large percentage of the peanut seed, this study attempted to associate protein markers with previously reported aflatoxin-resistant genotypes. Variation was observed among 24 genotypes for electrophoretic banding patterns, but it was not possible to correlate the presence or absence of specific bands with aflatoxin resistance.
