| 摘 要： | 对布设在安徽祁门县的首批84个枫香子代测定林，分析比较了9年生与3年生两个不同林龄胸径、树高性状的遗传力和遗传增益等参数，并开展了优良家系选择。结果表明不同时期入选的家系名称、数量及名次出现较大差异，大部分家系胸径、树高性状的家系遗传力、单株遗传力及遗传增益等参数估值，表现为随林龄增大而降低。研究结果为枫香良种选育的适宜林龄提供了参考依据。

| Abstract: | Based on data of 84 progenies of firstling forest of Liquidambar formosana located in Qimen County of Anhui Province,basal diameter,tree height,the genetic traits and genetic gain of tree height were analyzed between forest of 9-years-old and 3-years-old,then conducted fine family selection.The results showed that the name,quantity and position of the family of different selected period appeared large differences.Parameter estimation of the most families,such as diameter,the family genetic traits of tree he... |
