摘要：

The objective of this study was to evaluate genotypes toward the identification of superior West Indian Cherry (Malpighia emarginata L.) parents that produce high-performing progenies. Parents clones were evaluated in a completely randomized design with three replications and each plot consisted of three plants. Fourteen genotypes of West Indian Cherry were characterized in Londrina, PR, Brazil. Nine quantitative characters of bigger agronomic interest were used for determination of genetic distance and identification of similar groups among the genotypes. The grouping by the method, based on Mahalanobis generalized distance, made it possible to organize the 14 genotypes in three groups. The genetic divergence based on a key agronomic character (level of vitamin C) allowed to recommend the cross as of the following genotypes: amarela mole (group III) with genotypes PR AM, N000 18, PR 17, PR 16, Eclipse, AM 22 and Dominga all of them group I.
