A study was conducted to establish variations in sweet potato feathery mottle potyvirus concn during storage and determine the best time to index the storage roots to be used for planting. Sweet potato plants from 2 clones were inoculated 20, 75 and 120 d after planting out by shoot grafting with plant material affected with chlorotic dwarf. Storage roots were identified, weighed at harvest and stored at 15-17 degrees C, RH 80-90%.
