摘要:

本文评述了群体同工酶基因位点遗传结构研究中的主要度量方法及其在森林树种中的应用概况。群体遗传结构可由单位点和多位点两类参数度量。 文中对这两类度量及其关系分别进行了讨论。阐明了多位点遗传结构的信息对林木改良和资源保存策略的重要意义。

Abstract

The main methods to characterize population genetic structure at isozyme loci and their applications in forest  trees  were  reviewed.The population genetic structure can be characterized by two  sets  of measurable parameters: single-locus measures and  multilocus  measures.These two sets of parameters and the  relationship  between  them  are  discussed.   The  contribution  of  multilocus  associations  to  the development of population genetic structure and  its  implication  for genetic conservation and breeding are elucidated.
