Title Research on the Aflatoxin Problem in Groundnut at ICRISAT
 
Creator Mehan, V K
McDonald, D
 
Subject Groundnut
 
Description Aflatoxin contamination of groundnuts is a serious problem in most
groundnut producing countries and as such is given high research
priority at ICRISAT. Since 1979, we have concentrated on selecting
cultivars resistant to seed invasion and colonization by
toxigenic strains of Aspergillus flavus, and/or to aflatoxin
production. Resistance to invasion and colonization by A. flavus
of rehydrated, mature seed has been found, and confirmed, in some
cultivars. Such resistance is of value in the event of the stored
groundnuts absorbing sufficient moisture to permit fungal growth.
We have also screened cultivars for field resistance to invasion
of seeds by A. flavus, both under natural conditions and with
inoculum of the fungus added to the soil in the pod zone. Some
cultivars with resistance to seed colonization also showed resistance
to field invasion by A. flavus. None of the cultivars tested
has yet shown complete resistance to aflatoxin production, but
significant differences occurred in amounts of aflatoxin produced
in seeds inoculated with a toxigenic strain of A. flavus.
