Collection, ex situ conservation and characterization of mangaba (Hancornia speciose Gomes) germplasm in coastal lowland of Northeastern Brazil

Abstract

This study aimed to evaluate the Mangaba Genebank of Embrapa Tabuleiros Costeiros, Brazil, since its implementation in 2006 and characterize the accessions in the reproductive stage. We used 21 descriptors (botanical, morphological, growth, biometric, and physicochemical) to assess mangaba germplasm, as well as the data of enrichment and survival since the genebank implementation. There was a success in the enrichment, maintenance, and diversity of the germplasm evaluated. The results showed a significant difference between the accessions for most descriptors. The fruits presented good quality characteristics both for fresh consumption and processing. Moreover, these results supported the publication of the minimum descriptors for this species by Bioversity International and Embrapa. The knowledge of mangaba variability will subsidize conservation strategies and should encourage future researches on breeding.

Diversity, genetic structure and core collection of mangaba (Hancornia speciosa) genebank

“…Popularly known as mangaba, the species belongs to the Apocynaceae family with a wide distribution in the Neotropics, being reported in Brazil, Paraguay, Bolivia and Peru (Collevatti et al 2018;Fajardo et al 2018). In Brazil, it can be seen from Amapá, in the North, to Paraná, in the South, in different phytophysiognomies associated with the Cerrado and the Atlantic Forest (Silva et al 2021).…”
