A total of 768 molecular markers were developed for (L.) Lam., consisting of 689 simple sequence repeats (SSRs) and 79 single nucleotide polymorphisms (SNPs). All the markers were distributed across the sweet potato genome, averaging 51 markers per chromosome. The markers were tested on DNA samples from five cultivars of , assessing their amplification efficiency and polymorphism. Here we provide the primer sequences tested, their chromosome locations, the analysis including amplicon sizes, and highlight 92 that showed polymorphism between Beauregard and Tanzania. This dataset offers valuable resources for constructing high-resolution linkage maps and facilitates advanced genetic studies and breeding programs in sweetpotato.
总共为甘薯（Ipomoea batatas (L.) Lam.）开发了768个分子标记，其中包括689个简单序列重复（SSR）和79个单核苷酸多态性（SNP）。所有标记均分布在甘薯基因组中，平均每条染色体有51个标记。这些标记在五个甘薯品种的DNA样本上进行了测试，评估了它们的扩增效率和多态性。在此，我们提供了测试的引物序列、它们在染色体上的位置、包括扩增子大小的分析，并突出显示了92个在波瑞加德（Beauregard）和坦桑尼亚（Tanzania）之间表现出多态性的标记。该数据集为构建高分辨率连锁图谱提供了宝贵资源，并促进了甘薯的高级遗传研究和育种计划。
