| 摘 要： | 通过对18年生马尾松种子园自由授粉子代测定林生长性状的调查分析,进行优良家系及单株的选择。结果表明,马尾松种子园自由授粉子代在树高、胸径、材积性状上存在显著的遗传变异;利用30%和15%的入选率对参试的2个测定组进行选择,选择出20个速生优良家系,平均材积遗传增益为11.31%;选择出38株优良单株,平均材积遗传增益81.89%。

| Abstract: | Fine family and individual selection were carried out based on analysis of 18-year-old Pinus massoniana seed orchard open-pollinated progeny test stand growth characters.The results showed that there were significant growth differences among heights,dbh,and volume characters of families.Selection rates of 30% and 15% were used to select families for different test groups.20 superior families and 38 superior individuals were selected,finally.Family and individual average volume genetic gain were 11.31% and 81.89%,separately. |
