Resumo: The objective of this work was to analyze the genetic diversity of 47 table grape accessions, from the grapevine germplasm bank of Embrapa Semiárido, using 20 RAPD and seven microsatellite markers. Genetic distances between pairs of accessions were obtained based on Jaccard's similarity index for RAPD data and on the arithmetic complement of the weighted index for microsatellite data. The groups were formed according to the Tocher's cluster analysis and to the unweighted pair‑group method with arithmetic mean (UPGMA). The microsatellite markers were more efficient than the RAPD ones in the identification of genetic relationships. Information on the genetic distance, based on molecular characteristics and coupled with the cultivar agronomic performance, allowed for the recommendation of parents for crossings, in order to obtain superior hybrids in segregating populations for the table grape breeding program of Embrapa Semiárido.

Distâncias genéticas entre pares de acessos foram obtidas com base no índice de similaridade de Jaccard para marcadores RAPD e no complemento aritmético do índice ponderado para dados de microsatélites. Os grupos foram formados de acordo com a análise de agrupamento de Tocher e com o método de agrupamento não ponderado (UPGMA). Os marcadores microsatélites foram mais eficientes do que os RAPD na identificação das relações de parentesco. As informações de distância genética, baseadas em características moleculares e aliadas ao desempenho agronômico das cultivares, permitiram a recomendação de parentais para cruzamentos, para a obtenção de híbridos superiores nas populações segregantes do programa de melhoramento de videira da Embrapa Semiárido.Pesquisa Agropecuária Brasileira2018-02-05T12:44:15Z2018-02-05T12:44:15Z2011-08-05info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf0100-204Xhttp://dx.doi.org/10.1590/S0100-204X2011000900010http://www.locus.ufv.br/handle/123456789/17250engv. 46, n. 9, p. 1035-1044, Sept. 2011Leão, Patrícia Coelho de SouzaMotoike, Sérgio Yoshimitsuinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T06:07:20Zoai:locus.ufv.br:123456789/17250Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T06:07:20LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
