Progress world wide in breeding groundnuts resistant to seed colonization by Aspergillus flavus and &atoxin contamination is summarized, and research at ICRISA I'described. Resistance to A. flavus infection may occur at various levels, but efforts to breed for resistance have concentrated on the utilization of the resistance in the testae of matureseeds. At the International Crops Research Institute for the Semi-Arid Tropics (ICRISA T), genotypes identified as resistant to in vitro seed colonization by A. flavus have been crossed with susceptible cultivars of good agronomic character, and several breeding lines with stable resistance to seed colonization and with acceptable yield and quality have been produced. The genetics of inheritance of testa resistance is discussed. It is important that when breeding for resistance to A. flavus and aflatoxin production, breeders incorporate bther resistance traits.
