Six peanut cultivars, including both Virginia and Spanish types, were equally infected by Pratylenchus brachyurus as determined by the number of nematodes recovered from shells and pegs. However, lesions were not as conspicuous on pods of Virginia Bunch 67 and Georgia 186-28 as on Florigiant, Early Runner, Argentine, and Starr. Shell tissues of Virginia Bunch 67 and Georgia 186-28 were less sensitive either to the nematodes or to microbial effects, following nematode invasion, or to both.
