Ora-pro-nobis is a PANC (unconventional food plant) that meets the concept of “healthy foods”, due to its high nutritional value, presence of fibers and mainly proteins. This condition raises expectations for an increase in its consumption due to the growing search of the population for a healthier diet. Therefore, generating information about the genetic diversity of ora-pro-nobis materials becomes an important strategy to support future generations of technologies that will contribute to the expansion of this plant's cultivation. Therefore, the objective of this work was to carry out the structural, nutrient and molecular characterization of ora-pro-nóbis accessions that make up the germplasm bank of the Department of Agronomy Center of Agricultural Sciences and Engineering, Federal University of Espírito Santo (CCAE- UFES). For the variables of structural components (fibers, proteins and chlorophyll) and nutritional (N, P, Ca, Mg, Cu, Mn, Fe, Zn) a completely randomized design (DIC) was assumed, with four treatments (genotypes) and five repetitions to carry out the analysis of variance. For molecular analysis, markers of the type ISSR (Inter Simple Sequence Repeat) were used and the data submitted to similarity analysis by Jacard's coefficient and grouped by the grouping method of unweighted arithmetic means (UPGMA). The LAV-UFES 01 genotype stood out for having higher P and Cu content; LAVUFES 02 higher K, fiber and protein content; LAV-UFES 03 higher Mn and chlorophyll content; LAV-UFES 04 higher Ca, Mg, Fe and Zn content. It was considered that the studied genotypes are similar in terms of structural characteristics and nutrient content. There was no formation of groups by the UPGMA method, demonstrating that the genotypes have high genetic similarity.
