| 摘 要： | 对45个油松优树的半同胞子代进行了测定,从中选出8个树高、胸径、材积平均增产18.3%,28.4%和91.7%的优良家系,其遗传增益分别为12.8%,11.9%和30.9%。再从优良家系内选择44株优良单株,其树高、胸径、材积平均增产29.9%,36.9%和128%,预期遗传增益分别为11.7%,15.4%和43.2%,选出的优良单株可用于高世代种子园的营建。 |

| Abstract: | By means of halfsib progency test on 45 families of Pinus tabulaeformis, 8 excellent families were selected whose average height ,breast diameter and volume increased by 18.3%,28.4% and 91.7% with 12.8%,11.9% and 30.9% of genetic gains respectively. 44plus tree were further selected from the excellent families with increases of 29.9%,36.9% and 128% in average height,breast diameter and volume ,and their expectant genetic gains of 11.7%,15.4% and 43.2% respectively. The excellent individual selected can be used in building seed orchard of higher generation. |
