介绍了林木分子遗传图谱构建中所使用的分离群体和分子标记 ,着重综述了国内外林木遗传图谱研究的现状 ,对已建立图谱的树种的作图情况作了较详尽的总结 . The isolation groups and molecular markers used in the construction of tree molecular genetic map were introduced. The status quo of the research on tree genetic mapping both at home and abroad was reviewed. The mapping of tree species with established maps was summarized in detail.
