In-Vitro Determination of Kernel Resistance to Aspergillus flavus and Aflatoxin Accumulation in Groundnut

The study determined the level of resistance to Aspergillus flavus and to accumulation of aflatoxins in potential new breeding sources from ICRISAT Mali and in locally adapted groundnut genotypes commonly grown by Ugandan farmers. Genotypes were significantly different in their responses to A. flavus and to aflatoxin accumulation at P<0.001. Locally adapted genotypes that had both low A.flavus and accumulation of aflatoxins included Serenut 4, AGRA 99044 and erudu red, while AGRA 99033, Serenut 2, acholi white and red beauty had the highest levels of A.flavus and aflatoxin accumulations. High level of variations in the genotypes can be further used for genetic studies in order to establish effective and efficient breeding strategy for resistance to A.flavus and to the accumulation of aflatoxins in Ugandan lines.
