Resumo: This study aimed to evaluate the genetic dissimilarity among sweet potato genotypes using morphological and molecular descriptors. The experiment was conducted in the Olericulture Sector at Federal University of Jequitinhonha and Mucuri Valleys (UFVJM) and evaluated 60 sweet potato genotypes. For morphological characterization, 24 descriptors were used. For molecular characterization, 11 microsatellite primers specific for sweet potatoes were used, obtaining 210 polymorphic bands. Morphological and molecular diversity was obtained by dissimilarity matrices based on the coefficient of simple matching and the Jaccard index for morphological and molecular data, respectively. From these matrices, dendrograms were built. There is a large amount of genetic variability among sweet potato genotypes of the germplasm bank at UFVJM based on morphological and molecular characterizations. There was no duplicate suspicion or strong association between morphological and molecular analyses. Divergent accessions have been identified by molecular and morphological analyses, which can be used as parents in breeding programmes to produce progenies with high genetic variability.

O experimento foi conduzido no Setor de Olericultura da Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM) avaliando-se 60 genótipos de batata-doce. Na caracterização morfológica, utilizaram-se 24 descritores. Na caracterização molecular, utilizaram-se onze primers microssatélites específicos para batata-doce, obtendo-se 210 bandas polimórficas. A diversidade morfológica e molecular foi obtida por matrizes de dissimilaridade baseando-se no coeficiente de coincidência simples e índice de Jaccard, para dados morfológicos e moleculares, respectivamente. A partir destas matrizes foram construídos dendrogramas. Houve grande variabilidade genética entre os genótipos de batata doce do banco de germoplasma da UFVJM, tanto pela caracterização molecular como morfológica. Não houve suspeita de duplicata nem associação entre a análise molécular e morfológica. Foram identificados acessos divergentes pelas análises moleculares e morfológicas, os quais são indicados como genitores para compor programas de melhoramento a fim de obter progênies com alta variabilidade genética.Editora da Universidade Estadual de Maringá (Eduem)2019-08-23T20:15:45Z2019-08-23T20:15:45Z2017-12info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfANDRADE, E.
