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.

为了开发抗松材萎蔫病的松材品种，我们试图澄清九州地区松材线虫对松材萎蔫病的抗性差异以及该地区松材线虫毒力的多样性。经接种试验，九州地区采集的松苗平均成活率为16%左右（8 ~ 36%）。存活率因地区而异。结果显示了过去类似的趋势。说明不同区域松林对该病害的抗性存在差异。在毒力较强的松材线虫株系中，抗性较强的松材线虫株系成活率较高。结果表明，利用高抗性品种育苗可减少松材萎蔫病的危害。
