A Tennessee population (TN-79) of the soybean cyst nematode Heterodera glycines reproduced well on Bedford and Nathan, soybean cultivars resistant to SCN race 4. TN-79 also reproduced well on Essex, Lee, Pickett 71, and PI 88, 788 and moderately well on PI 87,631-1, J74-87, and Forrest. Soybean PI 89,772 and 90,763, cultivar Peking, and breeding lines D72-8927 and J74-88 were resistant to this population. TN-79 reproduced on soybean differentials similarly to SCN race 5 reported in Japan and a Minnesota population.
