Inheritance of resistance to aflatoxin production in the cross between corn inbreds B73 and LB31.

The inheritance of resistance to aflatoxin production in corn was studied following inoculation in progeny derived from the cross between the susceptible inbred B73 and the resistant inbred LB31.  Generation mean analysis showed that additive and dominant gene action were important for resistance to aflatoxin production.  Potence ratios indicated dominance for resistance.  Aflatoxin values of the F-1 generation were significantly lower than the calculated midparent values, indicating dominant gene action favouring resistance.  Results indicate that selection for resistance to aflatoxin production in progeny derived from the cross between B73 and LB31 should be effective.
