Agromorphological Characterization of Hibiscus sabdariffa L. Collection from Burkina Faso

Abstract

Hibiscus sabdariffa L. or roselle is an important vegetable crop in several African countries. It is rich in vitamins and minerals and is widely used in the diet of local populations in Africa, especially in Burkina Faso. However, up to now, there is no in-depth study describing roselle genetic diversity that has been carried out to assess ecotypes cultivated in Burkina Faso. Thus, this study aims to contribute to providing more insights into Hibiscus sabdariffa genetic variability in Burkina Faso through an agromorphological characterization. For this purpose, a trial was carried out using a Randomized Complete Block Design (RCBD) with three replications. 48 accessions collected from farmers were assessed. Agromorphological data collection involved 12 qualitative and 18 quantitative traits. The qualitative traits analysis showed high variability in leaf, stem, and flower color and shape. Analysis of variance (ANOVA), hierarchical cluster analysis (HCA), and principal component analysis (PCA) were performed using quantitative data. The results indicated significant differences among all genotypes for all the traits measured. The first three axes of the PCA explain 69.62% of the genetic variability. Furthermore, the results showed a high agromophological variability which is structured in three (03) groups. This variability will contribute to the enhancement and genetic improvement of Hibiscus sabdariffa.

Agro-morphological variability and prospects of genetic improvement of Hibiscus sabdariffa L. collections in some central Africa countries

“…The results of the evaluation of morphological and agronomic parameters showed an important genetic variability between the collections studied as also reported by Ouangraoua et al (2022). The height of the plant, as well as the height to the rst branch, which can be considered as indicators of plant Estimated heritability values ranged from 0.52 (IC to 1.0 (DIBF).…”

“…owering as reported by Bandi & Appalaswamy (2014). The study focused on Seven (07) quantitative parameters including plant height (HPL), height to rst branch (HPB), Collar diameter (DCO), number of branches (NB), owering date (DF), date of initiation of ower buds (DIBF) and chlorophyll content (IC) assessed 60 days after sowing according the approach reported by Ouangraoua et al (2022). The 13 qualitative traits concerned morphotype (MPT), leaf colour (CFE), leaf type (TFE), shape of leaf base (FBFE), shape of apex (FAP), colour of petiole (CP), petiole length (LPE), petal colour (CPE), stigma colour (CST), sepal colour (CSE), calyx colour (CCA), capsule shape (FCA), and number of separate lobes (NLS).…”

“…Growers use seed acquisition methods or practices that are widely known and traditionally established. These practices for seed acquisition are observed for various crops such as Abelmoschus esculentus L. (Okra) [10], Amaranthus sp. (Amaranthus) [11] and Hibiscus Sabdariffa L. (Guinea sorrel) [10].…”

“…These practices for seed acquisition are observed for various crops such as Abelmoschus esculentus L. (Okra) [10], Amaranthus sp. (Amaranthus) [11] and Hibiscus Sabdariffa L. (Guinea sorrel) [10]. In these modes of acquisition, the purchase is more common, and this is linked to the fact that the improved vegetable seeds available are generally hybrids, whose the agronomic performance diminishes after three years of use.…”
