摘  要：
以湖北省京山县太子山林场管理局马尾松无性系嫁接种子园半同胞8年生子代林为研究对象,在对胸径、树高、枝下高、冠幅和材积等生长因子进行实地调查的基础上进行遗传力分析.结果表明:不同半同胞家系林木各生长因子之间存在极显著性差异,显示马尾松半同胞家系林木间存在较为丰富的遗传变异,具有较大的选育潜力;8年生马尾松半同胞家系子代林树高、胸径和材积的遗传力分别为0.7436、0.6055和0.6500;采用20%的入选率时,筛选出5个优良半同胞家系且入选半同胞家系的材积、树高和胸径遗传增益分别为51.34%、17.45%和22.19%.

摘  要：
Using 8 years old half-sib progenies of Pinus massoniana stand from seed orchard of Jingshan County,Hubei Province as materials,growth factors such as diameter at breast height(DBH),tree height,height under branch,crown diameter and timber volume were measured.Results showed that there were significant differences for growth factors measured among different half-sib progenies,indicating that there were abundant genetic variation among half-sib progenies and potentials for selection.The heritability values of height,DBH and timber volume of 8 years old P.massoniana stand were 0.7436,0.6055 and 0.6500,respectively.Using 20% as selection percentage,5 superior half-sib progenies families could be selected,and genetic gains of timber volume,height and DBH were 51.34%,17.45% and 22.19%,respectively.
