摘要: 茶树世代周期长,自交不亲和,遗传组成高度异质杂合,利用常规育种方法培育新品种费时耗力。高质量的茶树遗传图谱,可以用于茶树基因组结构及遗传演化分析、数量性状位点定位、基因克隆,为分子标记辅助育种奠定良好的基础,对于加快茶树育种进程具有重要意义。本文对遗传图谱的构建原理、步骤及目前国内外茶树遗传图谱的研究进展进行简要概述,探讨了目前该领域研究中存在的主要问题,并由此提出加速茶树遗传图谱研究进程的设想。

Abstract: Conventional breeding of tea plant is laborious and time-consuming, due to long generation, self-incompatibility and high heterozygosity. A saturated genetic map is a vital tool in the analysis of genome structure, genetic evolution, QTLs (Quantitative trait loci), gene cloning and MAS (Marker assisted selection), which may provide great potential for accelerating cultivar improvement programme in tea plant. This paper introduced the construction theory and procedure of genetic mapping, as well as research progress and problems encountered by previous workers in genetic map construction of tea plant. Finally, we proposed improved strategies for the construction of genetic map of tea plant.

Key words: Camellia sinensis, genetic map, SSR
