Resumo: Fifty bean (Phaseolus vulgaris L.) samples from the Active Germplasm Bank of Embrapa - Centro Nacional de Pesquisa de Arroz e Feijão (CNPAF), Goiânia, GO, Brazil, were studied using multivariable techniques to screen descriptors for characterization, to measure genetic diversity and to group samples, looking for repetitive access identification. Germplasm evaluation was carried out in June 1993, using the randomized block design with two replications. Ten quantitative and phenologic descriptors were used for characterization and analysed by canonic variables and Mahalanobis distance techniques. There were no redundant characters and all descriptors were important for sample description. The grouping technique using the diversity genetic measures through the Mahalanobis generalized distance showed to be efficient and viable for identification of repetitive samples, being an appropriate procedure to be used in genebanks.

Cinqüenta acessos do Banco Ativo de Germoplasma (BAG-Feijão), da Embrapa - Centro Nacional de Pesquisa de Arroz e Feijão (CNPAF), foram avaliados em junho de 1993, utilizando-se delineamento experimental em blocos casualizados, com duas repetições. Dez descritores com características quantitativas e fenológicas foram analisados por meio de variáveis canônicas e distância de Mahalanobis. Todos os caracteres foram importantes na descrição do germoplasma. A técnica de agrupamento pela distância generalizada de Mahalanobis mostrou-se viável e eficaz na identificação de duplicidades do feijoeiro, podendo ser utilizada rotineiramente no Banco de Germoplasma.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFonseca, Jaime Robertoda Silva, Heloisa Torres1999-03-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5186Pesquisa Agropecuaria Brasileira; v.34, n.3, mar. 1999; 409-414Pesquisa Agropecuária Brasileira; v.34, n.3, mar. 1999; 409-4141678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5186/2378info:eu-repo/semantics/openAccess2010-07-08T11:38:57Zoai:ojs.seer.sct.embrapa.br:article/5186Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-08T11:38:57Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
