Abstract

The genus Desmanthus presents wide ecogeographical distribution and complex taxonomy. Desmanthus pernambucanus (L.) Thellung, popularly known in Brazil as Jureminha, is a leguminous species native to the Northeast region of Brazil, which stands out by its high protein content, resistance to droughts, and by presenting no toxicity to animals. The objective of this work was to evaluate the genetic diversity of 15 progenies from the Commonwealth Scientific and Industrial Research Organization (CSIRO; Australia), through germplasm exchange for enrichment of the Desmanthus genebank of Embrapa Tabuleiros Costeiros, in Nossa Senhora das Dores, SE, Brazil. Fifteen ISSR markers were used, from which 8 were selected. The progenies identified as 242, 245, 246, 255, and 268 were the most genetically distant, and the most recommended to be introduced to the genebank.
