Resistance to Osborne's Cyst Nematode in Selected Nicotiana Species.
Resistance to an undescribed species of Heterodera, Osborne's cyst nematode, was compared in Nicotiana glutinosa, N. paniculata, N. plumbaginifolia and N. Iongiflora. These species were differentially resistant in greenhouse tests as shown by nematode development, the reaction of the invaded roots, and the expression of resistance in interspecific hybrids.
