Breeding objectives for pulp, woodchip and standing wood volume production systems were developed in Eucalyptus urophylla under typical condition in South East China. The relative importance of the traits in breeding objective including volume, wood basic density and pulp yield were calculated. The selection indices for these objectives were also constructed based on selection criteria which included diameter at breast height, tree height, relative bark thickness and Pilodyn penetration. The results showed that volume is a dominant trait in determining the economic benefits in short-rotation species. The important of pulp yield in breeding objective cannot be materialised by selection index as the indirect traits are poor indicators of this trait
