Crop Breeding and Applied Biotechnology, Viçosa, v. 21, n. 2, p. 1-10, abr./jun. 2021.1984-7033http://dx.doi.org/10.1590/1984- 70332021v21n2a32http://www.sbicafe.ufv.br/handle/123456789/12892The state of Espírito Santo is the major producer of Coffea canephora in Brazil. Knowledge of genetic reserves is fundamental to plant breeding. Therefore, the present study characterized and analyzed the genetic diversity of 600 C. canephora accessions from the germplasm bank of Incaper based on 38 traits evaluated in 24-30-month-old plants. Further, the predominant descriptors or traits were identified, and high phenotypic variability was determined. Genetic distances for the grouped (Gower), quantitative, and qualitative datasets were 0.48, 0.61, and 0.92, respectively, with accessions 76 (Conilon) and 407 (Robusta) being the most divergent ones at Incaper. In clustering using the Tocher optimization method, 30 groups were formed, with three accessions introduced from Epamig’s Robusta collection being the most dissimilar ones. Graphical dispersion analysis using the principal coordinate method revealed the predominance of three groups formed by the Robusta, Conilon, and hybrid Robusta × Conilon genotypes.pdfenOpen AccessBreedingSelectionConilon coffeeGenetic divergenceGenetic resourcesCafeicultura::Genética e melhoramentoArtigo
