Interpretive Summary:

Technical Abstract: Current potato seed potato certification relies primarily on visual inspection of potato fields during the growing season followed by post-harvest grow outs for detecting viruses, such as Potato Virus Y. However, because of the emergence of new viruses that do not always display symptoms and a desire for potato seed growers to obtain results earlier, there was a need for improving potato tuber testing. ARS researchers in Ithaca, NY, along with collaborators have been testing a high throughput molecular based diagnostic assay using tubers at harvest. This method of testing is presented as an option to supplement and expedite certification information for a seed lot and facilitate grower decision making. This assay will collectively provide the potato industry with swifter and more accurate seed health data.
