Abstract: The genetic map of jujube is a vital tool in marker assisted selection. High-density genetic map of jujube is beneficial for analysis of genetic evolution and QTLs. In order to study map-based cloning of genes important agronomic traits and accelerate breeding of jujube. The research progress of genetic map of jujube in China and abroad is summarised in this paper, including the design of parents combination, identification of real filial generation, construction of mapping population, construction of genetic map and QTLs, Additionally, we analyzed the problems encountered by previous workers and proposed improved strategies. It will lay a foundation for prediction candidate genes of agronomic trais and molecular assisted selection breeding of jujube.

Key words: jujube, genetic map, QTL

摘要: 枣遗传图谱是枣树分子辅助育种的重要工具之一。高质量的枣遗传图谱在遗传演化分析、QTLs基因定位等研究中发挥了重要作用。为开展图位克隆重要农艺性状基因、加快枣育种进程,本文简要概述了目前国内外枣遗传图谱的研究进展,包括设计亲本组合、真实子代鉴定、构建作图群体、遗传图谱构建和相关QTL定位研究等方面,进一步探讨前人研究存在的问题并提出相关解决措施,为开展筛选农艺状候选基因和枣分子辅助育种研究奠定了理论基础。
