陆地棉（Gossypium hirsutum L.）是刺激努力利用所需的多态性标记为基础的育种。G. raimondii和G.植物园和下一代测序（NGS）技术促进了棉花高通量标记技术的发展。遗传多样性、QTL作图和标记辅助选择（MAS）的概念正分别发展为更有效的连锁不平衡、关联作图和基因组选择的概念。本文从以下四个方面对近十年来棉花分子标记技术的发展进行了分析：（i）棉花中可用的低通量和高通量标记技术的比较分析，（ii）棉花可用的野生和改良基因库中的遗传多样性，（iii）鉴定棉花基因组中潜在经济性状的基因组区域，和（iv）基于标记的选择方法。此外，还对标记技术在提高棉花育种效率方面的应用进行了综述。上述基因组学技术和其他几种组学资源的整合有望提高棉花生产力，满足全球纤维数量和质量的需求。
Narrow genetic base and complex allotetraploid genome of cotton (Gossypium hirsutum L.) is stimulating efforts to avail required polymorphism for marker based breeding. The availability of draft genome sequence of G. raimondii and G. arboreum and next generation sequencing (NGS) technologies facilitated the development of high-throughput marker technologies in cotton. The concepts of genetic diversity, QTL mapping, and marker assisted selection (MAS) are evolving into more efficient concepts of linkage disequilibrium, association mapping, and genomic selection, respectively. The objective of the current review is to analyze the pace of evolution in the molecular marker technologies in cotton during the last ten years into the following four areas: (i) comparative analysis of low- and high-throughput marker technologies available in cotton, (ii) genetic diversity in the available wild and improved gene pools of cotton, (iii) identification of the genomic regions within cotton genome underlying economic traits, and (iv) marker based selection methodologies. Moreover, the applications of marker technologies to enhance the breeding efficiency in cotton are also summarized. Aforementioned genomic technologies and the integration of several other omics resources are expected to enhance the cotton productivity and meet the global fiber quantity and quality demands.
