林木遗传图谱的构建策略及存在的问题

Construction strategies of genetic linkage map of forest trees and existing problems

遗传图谱是开展数量性状基因定位、标记辅助育种以及基因克隆等研究的基础,在理论和育种实践上都具有重要的意义,本文较为详尽地阐述了林木遗传图谱的构建过程,针对林木的自身特点探讨林木遗传图谱的作图策略,同时指出当前林木遗传图谱构建中存在的问题,并对林木高质量遗传图谱构建提出展望。

Genetic linkage maps provide a basic platform in genomic studies and breeding in a variety of ways. Base on the genetic linkage maps, the markers tightly linked to traits of interest were useful for QTL detection, marker-assisted selection（MAS） and marker-assisted cloning. The process of genetic map construction for forest trees was summarized, the strategy in constructing genetic linkage maps of trees according to their characteristics was reviewed, and the existing problems in genetic mapping for forest trees were pointed out. Finally,prospect was made for constructing the high quality genetic map of forest trees.
