Abstract

To cope with pine wilt disease the first resistance breeding program started in western Japan in 1978. In this program, resistant Japanese black pines (Pinus thunbergii) and Japanese red pines (P. densiflora) were selected. Subsequently, their progenies have come into wide use as resistant seedlings. Breeding programs are also carried out in the other parts of Japan and Anhui Province in China, and resistant pines, including Ryukyu pine (P. luchuensis) and Masson pine (P. massoniana), are also being selected. The demand for more resistant pines is increasing. In Kyushu region, second-generation breeding that creates more stable resistant cuttings has been carried out since 2004. Since resistance to the pine wood nematode (PWN) seems to be a polygenic trait, gathering genes in a single cultivar by crossing resistant clones would make resistance higher.
