“…These accessions also exhibited reciprocal monophyly based on phylogenetic analysis. This corroborates the phenotypic diversity studies on H. compressa where accessions from Kwale exhibited the highest phenotypic diversity compared to other regions (Omire et al, 2020b).…”

“…There is scanty information on the genetic diversity of doum palm which limits access to its important traits and thus hinders its improvement. Previous diversity studies on H. compressa focussed on accessing the variability of its morphological traits (Omire et al, 2020b). The study identified five morphotypes with accessions from the Kenyan Coastal area being the most heterogeneous.…”

Doum palm (Hyphaene compressa) is a perennial economic plant primarily growing in Kenya’s Arid and Semi-Arid Lands (ASALs). It is heavily relied upon for food, animal feed, construction materials and medicine, making it an ideal plant for resource sustainability. However, the limited information on its genetic resources has hindered its breeding and conservation studies. This study used the genotyping by sequencing approach to identify Single Nucleotide Polymorphisms. These SNPs were further used to assess the genetic diversity and population structure of 96 H. compressa accessions from Coastal, Northern and Eastern ASAL regions of Kenya using two approaches; reference-based and de novo-based assemblies. STRUCTURE analysis grouped the sampled accessions into two genetic clusters (Cluster 1 and Cluster 2). Cluster 1 included accessions from the Northern region, whereas Cluster 2 included all accessions from Eastern and Coastal regions. Accessions from Kwale (Coastal) had mixed ancestry from both Cluster 1 and Cluster 2. These STRUCTURE findings were further supported by principal components analysis, discriminant analysis of principal components and phylogenetic analysis. Analysis of molecular variance indicated greater genetic variation within populations (92.7%) than among populations (7.3%). An overall FST of 0.074 was observed, signifying moderate genetic differentiation among populations. The results of this study will provide information useful in breeding, marker-assisted selection and conservation management of H. compressa.

Background: Hyphaene thebaica is a Palm tree or shrub often with dichotomous branching that is predominantly found in an open wet landscape, riverbeds/flood plains, and around river valleys. This study was conducted to document the ethnobotany of Hyphaene thebaica in the Afar depressions, Ethiopia.Methods: A purposeful sampling method was used to select the informants. A total of 80 informants -20 informants from each district and 15 of them in each district were women. Out of the selected informants 12 of them i.e., three from each district were considered key informants based on the recommendations from the administrators of different hierarchies who are believed to have sufficient knowledge about the plant and communities. The remainder (68 informants) were general informants. Direct matrix ranking was used to rank the preferred use of H. thebaica. Descriptive statistical analysis was performed using OriginPro 2022.Results: Results revealed that H. thebaica has numerous importance as implied by the informants in the Afar communities. These include material culture and Sennan Ari (100%), Doma (45%), and medicinal value (32%). The use preference ranking of the species revealed that material culture and making Sennan Ari were ranked first with 100% of the key informants confirming the information.Conclusions: The present study investigated the indigenous knowledge of the desert Palm, Hyphaene thebaica, and found the plant is multipurpose and is utilized for material culture production, temporary shelter/house (Sennan Ari) making, extraction of an alcohol/liquor, medicinal value, and income-generation. Advancing the material culture production by integrating current knowledge and phytochemical investigation on the alcohol extract and determining its efficacy is recommended.

“…There is increasing interest in doum palm domestication in some of the arid and semi-arid regions of Kenya. The drive for this is the decline in doum palm germplasm resources in these areas due to human interference and biotic stress [ 8 ]. H. compressain situ conservation is found in six protected areas and five ex situ conservation areas globally [ 9 , 10 ].…”

Hyphaene compressa is an economically important palm in Africa. Despite its significant role in the livelihoods of rural communities, the diversity of doum palm is poorly documented and studied. In addition, it has no model descriptor that can aid such studies. Ninety H. compressa accessions collected from Northern, Eastern, and Coastal regions of Kenya were examined to determine the morphological variability of the vegetative and fruit traits of H. compressa and to identify its morphotypes for improvement. A total of 19 morphological characters including seven quantitative and 12 qualitative traits of fruit and vegetative traits were selected. Linear mixed-effects models, principal component analysis, and linear discriminant analyses were used to assess the variation in the morphological traits of doum palm based on the regions. Hierarchical clustering was performed to identify the morphotypes of H. compressa. There was variability in H. compressa morphological traits, particularly at the Kenyan Coast. All seven quantitative traits were able to effectively discriminate doum palm phenotypically p ≤ 0.001 . The 90 accessions clustered into five morphotypes designated as 1, 2, 3, 4, and 5. Morphotype 4 was specific only to the Coastal region. Morphotype 5 had the tallest trees with the biggest fruits and included palms from Eastern and Coastal regions making it the best morphotype for fruit traits. This study will inform the domestication, improvement, and conservation of H. compressa by selecting elite accessions.
