摘要/Abstract

摘要： 对福建省华安金山林场25年生肉桂人工林的70株初选优树的半同胞子代进行遗传测定,方差分析结果表明,家系间在树高、地径上差异显著,参试的优树子代平均树高、地径分别超过对照家系78.6%、91.5%。通过聚类分析,初步分出5个类群,其中Ⅰ、Ⅱ类中11个家系属早期速生类型,有待于进一步重点观测。

Abstract: The heritability determination of seventy half-sibling progeny of Cinnamomum cassia was made in Jinshan Forest Farm, Huaan County, Fujian province. Analysis of variance revealed significant differences in tree height, DBH within families, and the tree height and DBH of being tested families were 78.6% and 91.5% greater than those of controls respectively. The group 1 and group 2, including 11 families, belong to early rapid growing type, which is necessary for further observation.

Key words: Cinnnamomum cassia, progeny test, genetic analysis
