Abstract: Brown spot disease is one of important diseases on Poms elliuttu,P. taeda,P. tunbergti in south China. Resistance selection of slash pine to brown spot disease has been made since 1982. 122 disease resistance phenotypes of slash pine were selected in heavy infected plantations in Fujian and Jiangxi provinces and 3 ha disease resistance cutting orchards were established by grafting with those phenotypes. Further screening by natural infection and artificial inoculation were conducted and 62 clones with high resistance were obtained. A seed orchard about 4 ha with disease resistance clones of slash pine was established in Fujian province.
