The objective of this work was to evaluate the genetic divergence between 32 clones of three clonal varieties of conilon coffee, to identify the most dissimilar for the establishment of programs of directed crosses. Genetic divergence was evaluated by multivariate procedures: generalized Mahalanobis distance, the grouping optimization method of Tocher and the technique of canonical variables. Seven characteristics were evaluated in one trial conducted in Marilândia, ES, Brazil. Genotypes ES 92, ES 25 and ES 22 are the most divergent; the last two are the most appropriate for crossing and to obtain hybrids of improved performance by using genetic divergence for good productive performance.

O objetivo deste trabalho foi avaliar a divergência genética entre 32 clones de café conilon (Coffea canephora Pierre ex Frohener) componentes de três variedades clonais melhoradas, com vistas à identificação dos mais dissimilares, para o estabelecimento de programas de cruzamentos dirigidos. A divergência genética foi avaliada por procedimentos multivariados: distância generalizada de Mahalanobis, método de agrupamento de otimização de Tocher e técnica de variáveis canônicas. Sete caracteres foram avaliados em experimento conduzido em Marilândia, ES. Os genótipos ES 92, ES 25 e ES 22 são os mais divergentes, sendo os dois últimos os mais indicados para cruzamento com os demais, tendo em vista aliarem divergência genética a um bom desempenho produtivo.
