Bedford, Bragg, Forrest, Hardee Late Selection, Hutton and Jupiter soybeans were tested for their susceptibility to a race 4 population of Meloidogyne incognita from okra in greenhouse studies. Based on gall index and larval population levels, Hutton is highly resistant to this root-knot nematode population, while the remaining cultivars were susceptible. Many well-developed females with eggs were present in the roots of susceptible plants, while few were present in the roots of Hutton. Histological examination of roots of susceptible cultivars showed an average of six thick wall, multinucleated giant cells within parenchyma cells of the vascular tissue. Very few small giant cells were located in the vascular tissue of Hutton around the head of female nematodes.
