| Descrição: | The objective of this work was to study by different methods of multivariate analysis the genetic divergence of forty genotypes of conilon coffee of the Coffee Genetic Improvement Program of the Capixaba Institute of Research - Incaper. In the analysis of dissimilarity, evaluated by the generalized distance of Mahalanobis, the genotypes most dissimilar were ES 318 and ES 01 in Sooretama, and ES 309 and ES 315 in Marilândia, Those most similar were ES 330 and ES 336 in Sooretama and ES 324 and ES 333 in Marilândia. In the study of clustering by the technique of Tocher, the genotypes were distributed in ten groups in Sooretama and five in Marilândia. In both locations there was good agreement in the disposition of the genotypes,in amount of genetic divergence, when the hierarchical nearest neighbor method and the method of Tocher were used. We verified good genetic divergence among the clones for the differents biometric methodologies studies. The results obtained, associated to the main agronomic characteristics evaluated, were important for the strategies addressing genetic improvement through sexual and asexual reproduction and propagation. The clones ES 01, ES 308, ES 309, ES 311, ES 321, ES 327, ES 328, ES 329, ES 330 and ES 337 are promising clones to be maintained and used in the Program of Improvement. |
