Genetic Enhancement of Groundnut for Resistance to Aflatoxin Contamination

(Hari D Upadhyaya and F. Waliyar)

Aflatoxin contamination of groundnut seeds, caused by aflatoxin producing fungus Aspergillus flavus, can occur in the field when the crop is growing, during harvesting and curing, and in storage and transportation. Aflatoxin contamination adversely affects quality of groundnut product, health of consumers and hampers international trade. Breeding for aflatoxin resistance has been in progress at ICRISAT and several breeding lines with improved performance for resistance to aflatoxin contamination and high yielding potential have been developed which can help to significantly reduce aflatoxin contamination in farmers’ fields when used with pre- and postharvest management practices. The transgenic resistance against fungal infection and aflatoxin production in combination with conventional breeding efforts may lead to the development of agronomically superior groundnut cultivars that are free of aflatoxin contamination.
