Abstract: A systematic study made in Linhai on wood properties of paper pulpwood of 17 new clones and other 3 clones as a control shows that the fiber length in the trunk of these 20 clones ranges between 0.966 0 and 1.143 0 mm , which has met the standard laid down by the International Timber Society for the fiber of middle rank and the specific gravity of the trunk is from 0.318 8 to 0.368 2 gcm-3 ;that the fiber length of branches ranges from 0.63 to 0.78mm and their specific gravity is from 0.344 2 to 0.400 8 gcm-3 ;that each clone differs from the other in timber properties either significantly or most significantly ;and that both fiber length and specific gravity have a relatively high genetic repetition (0.473 7 ~ 0.833 3).Genetically speaking , DBH is moderately in negative correlation between timber properties .Such 4 clones among 17 new clones as 367 , 366 , 370 and 351 are very prominent in growth and wood properties , their growth and wood properties being superior to those of Populus deltoides cv . 'Lux' that is best in pulping at present .Therefore , these four clones are a top choice for establishing a short-rotation forest armed at producing paper pulpwood and fiber wood .
