Resistance to aflatoxin accumulation in kernels of maize inbreds selected for ear rot resistance in West and Central Africa.

Thirty – six maize inbred lines selected in West and Central Africa for moderate to high resistance to maize ear rot under conditions of severe natural infection were screened for resistance to aflatoxin contamination using the previously established kernel screening assay. Results showed that more than half the inbreds accumulated aflatoxins at levels as low as or lower than the resistant U.S. Lines GT – MAS : gk or M182. In 10 selected aflatoxin – resistant or aflatoxin 0 susceptible inbreds. Aspergillus flavus growth was, in general , positively related to aflatoxin accumulation. Confirmation of resistance in promising African lines in held trials may significantly broaden the resistant germplasm base available for managing aflatoxin contamination through breeding approaches.
