Resumo(s)
Pine wilt disease (PWD) is caused by the endoparasitic nematode Bursaphelenchus xylophilus, or pinewood nematode (PWN). This disease is a serious environmental problem in Eastern Asia and Southwestern
Europe. In Iberian Peninsula, it severely affects maritime pine (Pinus pinaster Ait.) forests. Despite the high susceptibility of P. pinaster to PWD, heritable resistance has been observed in selected half-sib families after
PWN inoculation, showing that the implementation of breeding programs for PWD resistance is a viable and valuable strategy for managing this disease.
