V. de  aGenetic diversity in Amburana (Amburana cearensis) accessionsbhierarchical and optimization methods.h[electronic resource]  c2021  aThe evaluation of accessions in a germplasm bank is essential for determining the potential parents in conservation programs, especially for native trees. This study aimed to determine the genetic diversity among 68 Amburana cearensis genotypes from different locations in the state of Pernambuco, Brazil. Their genetic patterns were evaluated by Inter Simple Sequence Repeat (ISSR) molecular markers and genetic divergence was evaluated through multivariate analyses using different clustering methods. The optimization method used (Tocher) was in agreement with all the hierarchical models used, in which clustering of the genotypes occurred similarly, specifically for the accession BB116, which is an important genetic material to be preserved and studied. Among the various hierarchical methods applied, the Average Linkage method exhibited higher discrimination power, allowing identification of a larger number of divergent groups, thus implying wide genetic diversity among A. cearensis accessions.  aNatural resources  aBanco de Germoplasma  aCaatinga  aGenótipo  aImburana de Cambão  aPlanta Medicinal  aAmburana cearensis  aAmburana de cheiro  aÁrvore nativa  aConservação genética  aPlanta nativa1 aCARVALHO, J.
