Abstract
Results of peanut mottle and peanut stripe virus detection studies indicated that peanut seedlots were best handled by extracting nucleic acid from samples of seed slices pooled from rows and columns of seeds arranged in a grid. A portion of these RNA samples were then combined (plate pooled sample) and tested via RT-PCR. This approach could detect one infected seed in a 96-seed sample. The samples from the positive seedlots were then tested to determine the location of the virus-infected seeds. A similar approach with IC-RT-PCR tests of samples from rows and columns ground in buffer failed to produce consistent results. Both the RT-PCR and the IC-RT-PCR approaches were compared to the results with DAS-ELISA tests of the individual seeds. The approach of testing plate-pooled samples followed by row and column sample tests by RT-PCR resulted in faster and most reliable testing of seedlots
