Resumo: A group of washed seeds and thirty five genotypes of quinoa (Chenopodium quinoa, Willd) were screened by soap column method and were classified by RGB Color Model (R, red; G, green; B, blue) with the objective to determine the influence of the saponin content in the grain color. Yellow seeds presented high levels of saponin. There was negative correlation (p≤0.05) among soap column method and bands R (r = -0.751), G (r = -0.660) and B (r = -0.594). Four groups were fixed. Tests confirmed the access of group 4 as bitter (yellow seeds) and the access of group 1 as sweet (white seeds). The dispersion represents probable difference in gene frequency, reflected by the color and rate of saponin.

Sementes amarelas apresentaram alto teor de saponina. Houve correlação negativa (p≤0,05) entre o teste de coluna de espuma e as bandas R (r = -0,751), G (r = -0,660) e B (r = -0,594). Estabeleceram-se quatro grupos de similaridade. Foram considerados amargos os acessos do grupo 4 (sementes amarelas) e doces os acessos do grupo 1 (sementes brancas). A dispersão observada representa provável diferença na freqüência gênica, refletida pela cor e teor de saponina.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSouza, Luiz Augusto CopatiSpehar, Carlos RobertoSantos, Roberto Lorena Bastos2004-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6786Pesquisa Agropecuaria Brasileira; v.39, n.4, abr. 2004; 397-401Pesquisa Agropecuária Brasileira; v.39, n.4, abr. 2004; 397-4011678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6786/3842info:eu-repo/semantics/openAccess2014-07-17T17:07:22Zoai:ojs.seer.sct.embrapa.br:article/6786Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-17T17:07:22Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
