Interpretive Summary:

Technical Abstract: Seven peanut (Arachis hypogaea L.) lines containing anti-fungal transgenes and three runner cultivars (Okrun, Georgia Green, and Tifton 8) were evaluated in field plots in Tifton, Georgia, for their levels of post-harvest aflatoxin contamination (PAC) upon colonization by the fungus Aspergillus flavus. Georgia Green demonstrated the highest level of resistance to PAC followed closely by genotypes K24, K34, and Tifton 8. Moreover, genotypes K24 and K34 accumulated significantly less toxin than their parent genotype Okrun. These data confirm that at least two of the transgenic genotypes tested may have useful resistance to A. flavus.
