Abstract: In order to select materials with fast growth, sound wood quality and high fructification for advanced generation seed orchards of Pinus massoniana, the fructification, wood basic density and 2year investigation of the growth status of progenies from 139 plus trees of 19yearold P. massoniana in western Fujian province were conducted. Results showed that there were significant differences among all the traits studied. Seventy one excellent families were selected by the integrated assessment method, they had average tree height 131 m, average DBH 214 cm, average individual volume 0229 9 m3, average individual fructification 546 cones and average wood basic density 0391 1 g/cm3. Sixtynine plus trees were further selected from the excellent families, they had average tree height 1596 m, average DBH 293 cm, average individual volume 0.467 4 m3,average individual fructification 113 cones and average wood basic density 0.387 0 g/cm3.
