Abstract: Abstract: 【Objective】The study aimed to assess germplasm of the threatened species Dalbergia odorifera, select families with superior growth traits, and provide a reference for early seedling selection. 【Method】 We investigated and analyzed growth traits(height, diameter at breast height(DBH)and stem volume)in two eight-year progeny tests conducted in Baishengyuan in Yangjiang City and in Zhenhai Forest Farm in Kaiping City, Guangdong Province, and selected superior families based on a statistical genetic analysis of growth traits. 【Result】At eight years, tree height, DBH and stem volume in Baishengyuan were 4.30 m, 6.31 cm, and 0.006 1 m³, respectively, and in Zhenhai they were 4.97 m, 6.07 cm, and 0.007 9 m³, respectively. In Baishengyuan, the phenotypic coefficients of variation in height, DBH and stem volume were 18.37%, 34.39% and 63.93%, respectively, and in Zhenhai they were 18.31%, 32.61% and 60.75%, respectively. Moreover, the individual heritabilities of these traits were 0.22-0.41, and family heritabilities were 0.34-0.54. High genetic correlation coefficients were observed among three growth traits at two sites, with correlation coefficients of approximately 0.9. Significant interactions between genotype and environment were observed for three growth traits. The Type B genetic correlation coefficients were 0.61, 0.53 and 0.51 for height, DBH and tree volume, respectively. We selected 10 families from 45 common families at two sites. At eight years old, the means of height, DBH and stem volume for the selected families were 5.06 m, 7.31 cm and 0.009 2 m³, respectively, which represented an increase above population means by 9.28%, 18.28% and 33.33%, and genetic gains of 3.37%, 6.24% and 12.86%, in each case for height, DBH and stem volume, respectively. Twelve plus trees were then selected from superior families, and showed increased values for average height(53.04%), DBH(73.42%)and tree volume(232.78%). The genetic gains from these twelve plus trees showed increases of 15.57%, 24.60% and 64.07% for height, DBH and tree volume, respectively. 【Conclusion】There were high genetic variations within and among germplasm families of D. odorifera, which provided abundant genetic resources for improvement of the species.
