| Abstract: |
| Progeny test of Schima superba plus trees was carried out in Meinan forest farm in 2005. Data of individual tree height, DBH and volume were measured in 2012. Results of ANOVA showed that differences among families in all measured traits were significant. According to the magnitude of volume, 4 families were selected and average genetic gain in height, DBH and volume reached 13.7%, 12.8% and 15.8%, respectively. Meanwhile 7 individual tree were also selected, and the average genetic gain were as high as 31.9%, 42.6% and 59.7% in height, DBH and volume, respectively. |
