Using the 80 plus trees＇ seedlings of Fokienia hodginsii, progeny test was built on State-owned Forest Farm of Xikou, Xianyou. Based on the investigation of 5-year-old progeny test, there were very significant differences among families on tree height, tree breast diameter and timber volume which were mainly controlled by genetic factors. Timber volume for families at 5-year-old ranged from 0.000 06 m3 to 0.005 28 m3. Based on the timber volume, 16 superior families such as P004, X004, J006, N001, N002, G018 etc. and 15 superior individuals such as Ei001, Ei002, Ei003, Ei004, Ei005, Ei006 etc. were selected from progeny test. The average tree height , breast diameter and timber volume of 116 superior families at 5-year-old were above 4.10 m, 4.30 cm and 0.004 00 m3 respectively which had average genetic gains above 7.50%, 14.40% and 28.50% respectively. The average tree height, breast diameter and timber volume of 15 superior individuals at 5-year-old were above 5.50 m, 7.00 cm and 0.01190 m3 respectively which had average genetic gains above 22.10%, 40.90% and 101.90% respectively. These superior families and individuals showed good growth traits and could be used for seed orchard and vegetative propagation.
