Data from: Development of Diversity Arrays Technology markers as a tool for rapid genomic assessment in Nile tilapia, Oreochromis niloticus

The development of genomic markers is described for Nile tilapia, Oreochromis niloticus, using the Diversity Arrays Technology (DArT) genotype-by-sequencing platform. A total of 13 215 single nucleotide polymorphism (SNP) markers and 12 490 silicoDArT (dominant) markers were identified from broodstock of two selective breeding programs [Genetically Improved Farmed Tilapia (GIFT) strain from Malaysia and the Abbassa strain from Egypt]. Over 10 000 SNPs were polymorphic in either strain, and 2985 and 3087 showed strain-specific polymorphisms for the GIFT and Abbassa strains respectively. We demonstrate the potential utility of these markers for rapid genomic screening and use in breeding programs.

本研究以尼罗罗非鱼（Oreochromis niloticus）为研究对象，基于多样性阵列技术（Diversity Arrays Technology, DArT）分型测序平台开发基因组标记。研究从两个选择育种项目的亲本群体中，共鉴定得到13215个单核苷酸多态性（SNP）标记与12490个虚拟DArT（显性）标记，这两个育种项目分别为源自马来西亚的吉富品系（Genetically Improved Farmed Tilapia, GIFT）与源自埃及的阿巴萨品系。两个品系中均有超过10000个SNP标记呈现多态性，其中吉富品系与阿巴萨品系分别包含2985个和3087个品系特异性多态性SNP标记。本研究证实，上述标记可用于快速基因组筛选并应用于育种计划，展现出良好的应用潜力。
