dc.descriptionThe correct identification of Coffea canephora genotypes into the botanical groups Conilon, Robusta and their hybrids is fundamental for breeding strategies aimed at developing and selecting commercial clones; however, genotype discrimination is challenging when based only on morphological attributes. A total of 121 individuals were evaluated from the Incaper Active Germplasm Bank (BAG): 52 Conilon, 33 Robusta, and 36 hybrids (morphological intermediates showing traits of both groups). DArTseq SNPs were filtered, and 1,551 markers were used in the analyses. Cluster analyses revealed three genetic groups: one Robusta (G1) and two Conilon (G2 and G3). AMOVA indicated that 78.49% of the variation occurred among groups and 21.51% within groups. Differentiation was greatest between G1 and G3 (Fst = 0.77), followed by G1 and G2 (Fst = 0.46), whereas G2 and G3 showed lower differentiation (Fst = 0.31). G2 showed high genetic diversity and greater genotypic variability, with three SNP-defined genotypes, suggesting the presence of genetic hybrids. Ten SNPs, located on nine chromosomes and outside genic regions, were validated to discriminate the botanical groups, providing a molecular fingerprinting tool for the characterization of C. canephora germplasm in Brazil.
