“…Quality attributes of the core collection (Core) extracted form the whole collection (Whole). CV coefficient of variation, Cri coincidance range for the trait I, VRi variable range for the trait I, VDi variance difference for the trait I, MDi mean difference percentage for the trait i. www.nature.com/scientificreports/ dulcificum confirmed the prominence of long-living species in the Sapotaceae family 72 . The absence of difference of age between home garden trees and those found on farms ruled out the hypothesis that tree age is a driver of tree-traits variation between these two habitats in S. dulcificum.…”

The miracle plant Synsepalum dulcificum is a multipurpose natural sweetener and a promising West African orphan fruit shrub candidate for genetic improvement. Unfortunately, basic knowledge such as phenotypic variation and inheritance estimates required for implementing a breeding program are still lacking. A set of 203 accessions were sampled in two habitats from seven populations spread across the Dahomey Gap (DG) and the Upper Guinea forest (UG) in West Africa. The phenotypic diversity and allometric relationships among functional traits were analysed; the broad-sense heritability was estimated for fruit-traits, and a mini-core collection was developed in the species. Quantitative variation in tree- and fruit-traits was recorded, and multivariate analyses were performed to assess relationships among accessions, whereas heritability was estimated using the coefficient of repeatability. Tree-traits observed in S. dulcificum were more variable than fruit-traits. While habitat-type only affected tree-traits, the provenance population significantly affected both fruit- and tree-traits, with the UG populations outperforming the DG ones. Significant correlations were observed among fruit-traits on one hand, and among tree-traits on the other hand, whereas poor correlations were observed between tree- and fruit-traits. The multivariate analysis grouped accessions in three clusters. Promising individuals for high fruit mass and pulp-dense genotypes’ selection were identified within clusters. Repeatability estimates for fruit-traits ranged from 0.015 (edible ratio) to 0.88 (fruit mass). The Core Hunter algorithm enabled the extraction of 41 individuals as robust representatives of the initial set of 203 accessions, and the mapping of this core collection suggested Dahomey Gap as a centre of diversity of the species. These original findings offer opportunities, not only for the genetic improvement of S. dulcificum, but also for targeted ex-situ conservation in the species.

“…FAO 2005). As also argued by Hegde et al (2017) and Karambiri et al (2017) in this issue, the complementary sets of knowledge shown by different participant groups demonstrate the need to involve the differentiated segments of a community in research on NFTs and natural resources more generally to build on a holistic understanding of the knowledge held locally.…”

Sarawak, Malaysia, is home to a wide range of native fruit tree species (NFTs) that contribute to the livelihoods of rural women and men. Yet, most agricultural research in the area, and elsewhere, has focused on commercial, non-native species, and the economic potential of lesserknown NFTs has often been overlooked. What is more, little attention has focused on research for development tools that can build on the local ecological knowledge of both men and women while supporting forest-based livelihoods and biodiversity conservation. This study contributes to filling this gap by assessing the usefulness and ease of use of a set of participatory tools -Four Cell Analysis, Venn Diagrams, Participatory Value Chain Mapping and Participatory Rapid Market Appraisal -that enable villagers to engage in a genderresponsive learning process supporting livelihood initiatives around native fruit trees. Activities, which focused on mango (Mangifera spp.) and rambutan (Nephelium spp.), were conducted in two villages in Sarawak. Research was carried out within gender and age specific groups, which then came together to share and discuss their findings. Participants evaluated the tools and approach based on their usefulness to the community and their ease of use. Key findings were that women's and men's different yet overlapping knowledge about forest resources was well captured using the four tools. Although each tool generated useful information, the combination of tools was important for painting a fuller picture of ecological, organizational, and marketing aspects related to native fruit trees and the sequence of activities supported local learning processes. Participants found the four tools moderately easy to easy to use, and the process of working within gender and age segregated groups and bringing the groups together promoted freedom of expression within groups as well as inter-group learning.

“…Indeed, the natural and human selections could be at the origin of these groupings. The selection of elite trees based on farmers' preferences would have led to the selection of trees with identical performances from one locality to another (Gwali et al, 2012;Karambiri et al, 2016). Similarly, the allogamous nature of shea tree has been found to cause important gene flow between populations (Vaughan et al, 2007;Abasse et al, 2011).…”

Agromorphological diversity structure of the elite shea trees identified in village lands and conserved in situ in the districts of Bagoué and Tchologo by the shea breeding program of the University of Peleforo Gon Coulibaly (UPGC, Côte d'Ivoire), are not known. In the present study, we characterized the agromorphological parameters of 220 elite shea trees using a set of 12 quantitative traits. The results showed that elite shea trees population has been structured into three morphological clusters or genetic pools that do not overlap with the original geographic areas. Morphological Cluster I contain elite shea trees with small trunk diameters carrying large leaves and producing fewer fruits per tree. Morphological Cluster II consisted of elite shea trees with stronger trunks bearing small leaves and producing a high number of fruits per tree. Morphological Cluster III regrouped elite shea trees of medium trunk diameters carrying medium sized leaves; fruit production level is intermediate compare to preceding groups. The elite shea trees of morphological Clusters II, which are more interesting from an agronomic point of view, can be used as grafting trees for the production of high-yielding grafted plants for farmers in Côte d'Ivoire.
