Abstract

The Eucalyptus species are widely distributed in the temperate zone in the southern hemisphere and used as a raw material of pulp in Asian-Oceania region. The paper manufacturing industry has particularly high expectations to this tree because it has superior growth property and pulp quality. Since 1991, Oji Paper has been advancing the overseas forest plantation business for securing the forest resource and to protect the environment.<BR>Forestry Research Institute of Oji Paper has been studying the improvement of the productivity of Eucalyptus plantation in Australia. We have already isolated a lots of plus tree candidates which were selected by growth characteristics (height, diameter, etc.) from several plantation sites. We carried out the wood quality analysis of the candidates. The results of the analysis showed that there were great differences of basic density and pulp yields among the candidates, and suggested that it is very important to improve not only growth but also wood quality for the plantation business and paper manufacturing. Therefore, we have been progressing the Eucalyptus breeding project to improve the wood quality of the candidates. Our breeding project has two approaches. One is the conventional breeding method and the another is the molecular breeding method using the regulatory genes of wood quality. We report our current status of the project.
