Summary:Progress worldwide in breeding groundnuts resistant to seed colonization by Aspergillus flavus and aflatoxin contamination is summarized, and research at ICRISAT 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 mature seeds. Genotypes identified as resistant to in vitro seed colonization by A. flavus were crossed with susceptible cultivars of good agronomic character, and several breeding lines with stable resistance to seed colonization and with acceptable yield and quality were produced. The genetics of inheritance of testa resistance is discussed.
