Resumo: | This work was carried out at Epamig-CTZM experimental area in Oratórios, MG, during the summer of 1999, in order to evaluate the genetic divergence among 51 sweet potato clones from different Brazilian regions. A randomized complete block design with three replications was used. Each plot consisted of three rows of 3.0 m with the plants in the spacing of 1.00 x 0.25 m. The evaluations were done in five competitive plants located within an area of 2,0 m2 in the central row. Genetic divergence, based in 25 characteristics, was estimated by the Mahalanobis generalized distance and by two grouping methods, the Tocher’s grouping and the hierarchical nearest neighbor. Large genetic variability was detected among the clones, which were then grouped into seven heterotic clusters by the two methods. There was good agreement in the formation of the groups for the two methods. The occurrence of small genetic distances among some clones and the inclusion of more than a clone into a specific group indicate that it might be occurring duplication among the evaluated genotypes might be occurring |

Utilizou-se o delineamento de blocos ao acaso, com três repetições. As parcelas foram constituídas por três fileiras de 3,0 m, com plantas no espaçamento de 1,00 x 0,25 m, sendo considerada parcela útil 2,0 m2 da fileira central. As avaliações foram realizadas em cinco plantas competitivas, amostradas na parcela útil. A divergência genética foi avaliada pela distância generalizada de Mahalanobis e pelos métodos de agrupamento de Tocher e hierárquico do vizinho mais próximo, com base em 25 características. Detectou-se ampla variabilidade genética entre os clones, sendo estes reunidos em sete grupos heteróticos em ambos os métodos. Houve boa concordância na formação dos grupos pelos dois métodos. A verificação de pequenas distâncias genéticas entre alguns clones e a inclusão de mais de um clone em determinados grupos indicam a possibilidade de ocorrência de duplicidades entre o conjunto de genótipos avaliadosUniversidade Estadual de Maringá2008-05-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/284310.4025/actasciagron.v22i0.2843Acta Scientiarum.
