“…The results were on par with the works of Sivakumar et al, (2002), who reported that the fruit characters of Teak varied among the different locations. Similar variations in fruit traits between the various provenances has been recorded by the authors Ladipo et al, (1996), Atangana, (2010, Tsobeng et al, (2019) and Uma Shankar & Idaiarilin (2012). The results are supported by Munthali et al, (2012), who reported significant variations in fruit weight, length and width between different provenances and opined that the variations are due to environmental and genetic causes.…”

“…The present study observed that there was significant variation between the 16 selected population's in-terms of fruit and tree traits. Similar studies were conducted in all around the world in both annuals and perennials and reported the same kind of variations among the selected population (Atangana et al, 2001;Egbe et al, 2013;Mkwezalamba et al, 2015;Tsobeng et al, 2015;Tsobeng, 2020). Fresh fruits including three wings of phenotypically superior trees contain 75-80% moisture and the size of the fruit is smaller than any species under the taxa, Terminalia.…”

A reconnaissance survey was conducted in Southern Western Ghats, India to identify the wild populations of Terminalia paniculata. From the explorative survey, 16 natural populations from different localities of the study area were identified. Collected 36 fruits from each tree and fruit trait quantification of total 3456 fruits (36 x 16 x 6) from 16 populations were used for the study. Hierarchical clustering of selected populations and correlations among fruit traits and between tree traits and fruit traits visualised using a dendrogram. The results indicated significant differences in fruit traits like fruit fresh mass, fruit large wing length and fruit large wing width. Clustering of fruit characters for all the accessions revealed the genetic relatedness between accessions. It reveals that selected populations of T. paniculata belong to two major clusters and confirms that 16 populations are either adjacent or distant in-terms of fruit traits are independent of the geographical station. The relationship between fruit traits indicates a significant positive correlation between fruit traits ranging from 0.352 to 0.739. Even though fruit traits show significant correlation within, a non-significant and very week correlation was obtained with tree stand-up traits except tree girth with fruit large wing length (21.4 %).

“…This is likely to increase the magnitude of the differences observed in tree-traits between these two habitats. Information on tree age is rarely reported in studies tackling phenotypic diversity in perennial fruit trees [69][70][71] . In this study, the age estimates for S. www.nature.com/scientificreports/ Figure 9.…”

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.
