Abstract: Heterosis is a quicker, cheaper and easier method for increasing plantation production, and heterosis studies can provide the basis for exploitation of valuable hybrid combinations in breeding programs. Growth traits, wood properties, and bark percentage were assessed for 6 × 6 full diallel progenies of E. urophylla in southern China measured at age 4 years. Analysis of variance showed that there were significant differences on all studied traits except dynamic modulus of elasticity among combinations. The mean diameter at breast height, wood basic density, and dynamic modulus of elasticity were 9.40 to 12.20 cm, 0.45 to 0.47 g cm-3, and 5.04 to 5.72 GPa, respectively. The coefficients of variation ranged from 18.18% to 50.43% for growth traits, 9.07% to 55.24% for wood properties and 22.26% to 23.93% for bark percentage. The heterosis estimation on diameter at breast height, wood basic density, and dynamic modulus of elasticity were -24.07% to 18.74%, -14.23% to 9.17% and -25.53% to 16.28%. U22×U56 generally had higher heterosis of growth traits and wood properties through three sites. Same combinations had different original and reciprocal heterosis estimation at two sites even on same traits. The combinations of same parents always had similar original and reciprocal heterosis estimation.
