Research Abstract

For developing the resistant pines to pine wilt disease, we have attempted to clarify the difference between the resistance to the pine wilt disease of pine in Kyushu region as well as the diversity of virulence of the pine wood nematode of that region. After inoculation tests, the average survival rate of pine seedlings collected from Kyushu region were around 16%(8 to 36%). The survival rate was different depending on the region. And the results showed a similar trend of the past. This result was suggested that the resistance ability of pine to that disease was different by the regional pine forest. The pine seedlings derived from higher resistant ability had a higher survival rates in the pine wood nematode strains with relatively strong virulence. This result suggested that using seedlings derived from high resistance varieties reduce the damage of pine wilt disease.
