New tools to screen wild peanut species for aflatoxin accumulation and genetic fingerprinting.

ABSTRACT:

Background

Aflatoxin contamination in peanut seeds is still a serious problem for the industry and human health. No stable aflatoxin resistant cultivars have yet been produced, and given the narrow genetic background of cultivated peanuts, wild species became an important source of genetic diversity. Wild peanut seeds, however, are not abundant, thus, an effective method of screening for aflatoxin accumulation using minimal seeds is highly desirable. In addition, keeping record of genetic fingerprinting of each accession would be very useful for breeding programs and for the identification of accessions within germplasm collections.

Results

In this study, we report a method of screening for aflatoxin accumulation that is applicable to the small-size seeds of wild peanuts, in
