| 摘 要： | 通过对26年生柳杉初级种子园自由授粉子代测定分析表明:树高、胸径和材积等主要生长性状在家系间的差异达5%显著水平;并以生长性状值为主要指标,进行速生优良家系选择,从试验林中选择出速生优良家系16个,26年生时树高、胸径和材积的平均遗传增益分别为1.12%、4.46%和7.34%。选择出的优良家系具有生长量大、适应性强的特点,是非常宝贵的柳杉种质资源,推广应用前景较好。

| Abstract: | 26 years old Cryptomeria fortune primary seed orchard open-pollinated progenies test in this paper showed as follows: tree height,DBH,and volume reached 5% difference among families;meanwhile,taking the growth properties values as the main indexes,the fast-growing fine families were selected,through comprehensive comparison,16 excellent families with fast growth and adaptability had been selected,the average genetic gains of tree height,DBH and volume were 1.12%、4.46% and 7.34% respectively.These selected families would had big growth amount,and strong adaptability,it was a very rare Cryptomeria fortune idioplasm resource with wide application prospect. |
