Laboratory response of five maize varieties commonly marketed in Bihar Stat
e, India to aflatox:n-producing and -non-producing strains of Aspergillus f
lavus was studied. Despite the small number of samples studied, it was poss
ible to separate the maize genotypes into three groups according to their r
esponse, efficiently producing aflatoxins (good Substrates), no aflatoxins
producing (poor substrates) and ambiguous, depending on the strain used as
the inoculum.
