| Research Abstract |
The resistant level against Bursaphelenchus xylophilus was different among P. thunbergii clones. The rooted cuttings from resistant mother trees showed higher survival rate than that from susceptible mother trees after nematode inoculation. The shorter and thinner Pinus thunbergii cuttings tended to show better rooting ability. Although I selected nematode virulence using pine cuttings and seedlings with different resistant level, the resistant level of pines did not affect the virulence of the selected nematodes. Nematode isolates extracted from resistant forest and susceptible forest in Satsumasendai City showed almost the same level of virulence.
