Molecular markers are important tools to study genetic diversity, guiding characterization practices within the genus Capsicum. The objective was to characterize 26 Capsicum spp. genotypes using 13 molecular markers ISSR and 17 SSR. The genetic material for the study came from the collections of Capsicum spp. preserved at the Universidade Federal do Maranhão and the Instituto Federal do Espírito Santo, Campus in Alegre. The polymorphism of primers was analyzed from two dendrograms generated by the hierarchical method UPGMA, and their entanglement was obtained using the Tanglegram algorithm of the den extend package of the R software. The 26 Capsicum genotypes were structured in four and six groups of genetic diversity using the ISSR and SSR primers, respectively. Both markers were efficient to detect diversity among genotypes. No duplicates were found among the genotypes evaluated, showing genetic materials important both for diversity conservation and the development of new Capsicum spp. cultivars.

旨在表征辣椒属的显性与共显性标记。

分子标记是研究遗传多样性的重要工具,指导辣椒属的表征实践。目的是表征 26种辣椒属。使用 13 个分子标记 ISSR 和 17 个 SSR 的基因型。该研究的遗传材料来自辣椒属的集合。保存在阿雷格里校区的联邦大学马拉尼昂州和圣埃斯皮里图联邦学院。通过分层法UPGMA生成的两个树状图分析引物的多态性,并使用R软件的den extend包的Tanglegram算法获得它们的纠缠。26个辣椒分别使用 ISSR 和 SSR 引物在四组和六组遗传多样性中构建基因型。两种标记都可以有效检测基因型之间的多样性。在评估的基因型中没有发现重复,表明遗传物质对多样性保护和新辣椒属的发展都很重要。品种。
