Resumo: The objective of this work was to characterize the genetic diversity within and among cultivars and landraces of common bean from RAPD markers analysis, and to evaluate the capacity of this markers in clustering common bean genotypes according to domestication centers and seed color. Thirty five common bean genotypes including 13 commercial cultivars and 22 landraces, from State of Rio Grande do Sul, Brazil, were evaluated. Genetic distances were calculated using Sorensen-Dice's similarity coefficient, displayed in a dendrogram. RAPD markers were efficient in separating cultivars and landraces according to domestication centers, but not according to seed color. Mesoamerican commercial cultivars and landraces have been clustered in different groups. A high degree of similarity was observed among cultivars in use in Rio Grande do Sul.

Foram avaliadas 35 cultivares, 13 comerciais e 22 locais, de diversas regiões do Rio Grande do Sul. As distâncias genéticas foram obtidas pelo complemento do coeficiente de similaridade de Sorensen-Dice e a representação simplificada destas distâncias realizada mediante um dendrograma. Marcadores RAPD foram eficientes ao agrupar cultivares de acordo com o centro de domesticação, mas não foram capazes de separar as cultivares de acordo com a coloração da semente. Cultivares locais e comerciais, mesoamericanas, foram agrupadas separadamente. Cultivares comerciais, em cultivo no Rio Grande do Sul apresentam alto grau de similaridade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraEmygdio, Beatriz MartiAntunes, Irajá FerreiraNedel, Jorge LuizChoer, Eva2003-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6686Pesquisa Agropecuaria Brasileira; v.38, n.10, out. 2003; 1165-1171Pesquisa Agropecuária Brasileira; v.38, n.10, out. 2003; 1165-11711678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6686/3743info:eu-repo/semantics/openAccess2014-08-11T19:36:25Zoai:ojs.seer.sct.embrapa.br:article/6686Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-11T19:36:25Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
