The economic importance of Sweden’s forests is velI—known hut the productivity can become even better with improved plants from a good breeding programme. Through the years in Australia, Harry Wu has conducted many large scale research projects that have increased the productivity and quality of plantations of radiata pine (Pi,ius radiata) through genetic improvement. While continuing some of this work in Australia, his main focus in Sweden is how to increase breeding efficiency for Scots pine (Piiiiis sih’cstris) and Norway spruce (Picca ahics), two species with nnich longer rotation periods than the Australian pine.
