Wheat varieties Arthur 71, Coker 747, Coker 6815, Delta Queen, Double Crop, Florida 301, McNair 1813, McNair 1003, and Southern Belle were resistant to the root-knot nematode, Meloidogyne incognita. Sorghum varieties Funk G 421, Funk G 499 BR, Funk G 516 BR, Funk G 522 A, Funk G 522 BR, Funk G 550, Funk G 611, Funk G 623, and DeKalb D 55 were susceptible to M. incognita. All wheat and sorghum varieties tested were nonhosts of the reniform nematode, Rotylenchulus reniformis.
