| 摘 要： | 林木遗传图谱是林木遗传学家进行林木遗传改良的重要工具。由于林木生长周期长, 高度杂合, 且多为异交物种, 构建高密度的遗传图谱困难较大。文中对已构建的林木遗传图谱进行总结, 从遗传标记的选择、作图群体的构建和遗传作图策略3个方面综述林木遗传图谱构建的过程, 着重介绍林木遗传图谱构建的特殊之处, 指出作图过程中可能存在的问题, 并对构建高密度的林木遗传图谱进行展望。

| Abstract: | Forest genetic maps are an important component within the forest biologist's toolkit, underpinning forest improvement programs. The estimation of forest genetic maps is a conceptually simple yet computationally complex problem, due to long growth period and high heterozygosis and genetic load of forest trees. At present, some genetic maps of trees have been constructed. This paper reviewed the process of forest genetic map construction, highlighting its uniqueness, and pointed out the problems that might rise in mapping. Finally, prospect was made for constructing the high density genetic map of trees. |
