Location of aflatoxin‐containing seeds within locks of Aspergillus flavus contaminated bolls was determined. Of the 141 seeds examined from 22 intact locks, 78 exhibited bright greenish yellow fluorescence (BGYF) on the linters. Twenty‐four seeds contained aflatoxins ranging from 0.231 to 151.3 μg of toxin per gram of seed. Twenty‐one of these aflatoxin‐positive seeds had linters exhibiting BGYF, and three had nonfluorescent linters. With one exception, aflatoxin contamination was concentrated in only one or two highly contaminated seeds in the apex half of tight locks, and the rest of the three to five seeds were negative. Explanations for this type of infection are discussed.
