“…The fruit length, fruit mass, length-to-width ratio, number of seeds and mass of one seed showed lower P ST values after this variety was excluded from the analysis. This result suggests that the phenotypic variation in these traits may be affected by the taxonomic component, as observed in botanical varieties of Hancornia speciosa Gomes (mangabeira), another fruit species from the Brazilian Savanna (Chaves et al 2020).…”

Hymenaea stigonocarpa (Mart. Ex Hayne), popularly known as jatobá-do-cerrado, is a fruit tree widely distributed in the Brazilian Savanna, has multiple uses and is a promising genetic resource. This study aimed to physically characterize fruits and seeds of H. stigonocarpa, as well as to estimate the phenotypic variability at three hierarchical levels: populations, mother trees within populations, and fruits/seeds within mother trees. Fruits from six mother trees were sampled from each of the 25 natural populations found in the Brazilian Savanna. The morphometric characterization of 742 fruits was carried out by evaluating 10 quantitative traits in fruits and seeds. In addition, comparative analyses were performed between the average values of H. stigonocarpa and the botanical variety H. stigonocarpa var. brevipetiolata. Significant phenotypic variations were noticed at all hierarchical levels. A high phenotypic differentiation among the populations was observed for quantitative traits (fruit mass and size, pulp mass and seed mass), being higher when H. stigonocarpa var. brevipetiolata was included in the analysis.

“…Our results showed a greater morphological similarity between trees belonging to the same botanical variety of mangabeira, according to the classification proposed by Monachino (1945). According to Chaves et al (2020), the quantitative divergence within botanical varieties of this fruit species is mainly due to genetic drift, while the divergence among varieties is due to both drift and divergent selection.…”

Hancornia speciosa is a fruit tree species with potential for exploitation, which makes the adoption of strategies related to its conservation and breeding relevant. Our study aimed to investigate the reproductive phenology, estimate genetic variability, and identify superior H. speciosa genotypes among the accessions that compose the germplasm collection of the Federal University of Goiás, Brazil. Experimental data were obtained from 143 individual accessions. Evaluation of reproductive phenology was conducted on an arbitrary scale of points assigned to trees monthly. Morphological characterization was based on a list of 20 qualitative descriptors and 12 quantitative traits. The dissimilarity between and within botanical varieties and their correlation with the geographic distance of the origin populations were investigated. Analysis of variance components was performed using the Restricted Maximum Likelihood/Best Linear Unbiased Prediction procedure using two linear models. The selection of the ≈ 10% best individual accessions was performed considering genetic and genotypic values. With the exception of H. speciosa var. speciosa, the botanical varieties that compose the germplasm collection showed similar reproductive patterns, with a peak in fruit appearance in August. Morphological dissimilarity was smaller within botanical varieties. Among the botanical varieties, dissimilarity was generally positively correlated with the geographic distance. The adoption of a multivariate selection index procedure enables the prediction of genetic gains, resulting in the selection of genotypes from different similarity groups. Clone selection is the most promising strategy for the improvement of H. speciosa, ensuring a better response to selection in the short term than recurrent selection.

“…Technological products based on the species also followed this trend, and most of them were direct to the potential as food, from the processing of fruits and the development of products, such as liqueurs, cakes, and jellies. It is noteworthy that the studies of the widely distributed populations in the country that investigated the molecular differences among them, and botanical varieties of the species were less frequent (Collevatti et al 2016(Collevatti et al , 2018Chaves et al 2020).…”

Hancornia speciosa Gomes is a fruit and medicinal tree species native to South America, which in Brazil is considered of potential economic value and priority for research and development. We present a map of the state-of-art, including articles, patents, and molecular data of the species to identify perspectives for future research. The annual scientific production, intellectual, social, and conceptual structure were evaluated, along with the number of patent deposits, components of the plant used, countries of deposit, international classification and assignees, and the accessibility of available molecular data. Brazil has the most significant publications (306) between 1992 and 2020. Technological products (29) have been developed from different tissues of the plant. Most of the articles and patents were developed by researchers from public universities from different regions of Brazil. The molecular data are sequences of nucleotides (164) and proteins (236) of the chloroplast genome and are described to identify the species as DNA barcodes and proteins involved in photosynthesis. The compilation and report of scientific, technological, and molecular information in the present review allowed the identification of new perspectives of research to be developed based on the gaps in knowledge regarding the species and perspectives for the definition of future research.
