Analysis on main properties of 10-years Pinus massoniana at provenance seedling seed orchard established at Washan Forest Center of Quanjiao, Anhui province resulted that mean height, DBH and single volume of 17 tested provenances increased respectively 7.6%, 11.95% and 35.45% than that of the control of Qianshan provenance, that of 4 provenances from low hilly areas of Hunan and Jiangxi increased 10.52%, 16.15% and 50.34% than that of the control of Qianshan provenance, and that of 3 provenances form Guizhou high plateau (including Wuling Mountainous area) increased 10.8%, 13.3% and 43.17% than that of the control. Crown size and thickness of provenances from central plains was larger than that from the northern China, but primary seed bearing was higher than that from the northern China and the control. Analysis of variance demonstrated that evident or very evident difference existed among different provenances of height, DBH, volume, crown size and thickness, fruit quantity. Relative analysis indicated that main increment increased with decrease of altitude while fruit quantity increased with the increase of altitude.
