Dataset on the qualitative characteristics of roselle varieties (Hibiscus sabdariffa L.)
Abstract
Roselle (Hibiscus sabdariffa L.) is a worldwide known species of great importance due to its medicinal properties and pleasant flavor. In Paraguay, it is used as an alternative crop by family-run farmers; however, the varieties used in the country are unknown, so no information is available on this crop. The qualitative characterization would collect knowledge serving as a basis for the registration of varieties produced in Paraguay. In addition, such data are useful for future genetic improvement programs considering this crop. The present work was carried out at the Multidisciplinary Center for Technological Research and the experimental farmland of the Faculty of Agricultural Sciences of the National University of Asuncion, during the years 2022 and 2023. The main objective was to carry out a morphological characterization of four Roselle varieties: Ana Delia, Benito, Dogo, and Creole. The design consisted of completely randomized blocks, with four treatments (varieties) and four replications; each experimental unit (block) was composed of 24 plants, distributed in four rows; 12 plants, selected from the central rows, were harvested for the evaluations. Stem color, leaf shape, leaf margin, rib color, petiole color, flower color, calyx color, calyx sepal opening, capsule shape, capsule color, capsule anthocyanin coloration, and pubescence level were evaluated. The results demonstrate qualitative differences between the varieties, which help to compare and classify them for a better variety selection.
