Resumo: Rice grain have low protein content but they present glutelin, a protein of higher nutritional quality than proteins of other cereal crops. The objective of this work was to characterize, by morphological and molecular markers, some land races from Maranhão State, Brazil, with high protein content (over 10%) and tolerance to Al3+ and nutritional stress. The 33 varieties under study were fit in five groups based on morphology, and in four groups when RAPD markers were used. These two groupings are not coincident as far as grain protein content are concerned. High grain protein plants were found randomly all over the groups. However, highest proteins contents are associated with plants with the lowest length/width ratio.

O objetivo deste trabalho foi caracterizar, por meio de descritores morfológicos e moleculares (RAPD), algumas variedades tradicionais de arroz do Estado do Maranhão que apresentam altos teores de proteínas nos grãos (mais de 10%) e são tolerantes ao estresse nutricional e ao Al tóxico. As 33 variedades estudadas foram separadas em cinco grupos baseados nas características morfológicas e quatro grupos utilizando marcadores RAPD, que não coincidiram entre si. Teores elevados de proteína no grão estavam presentes aleatoriamente em todos os grupos. No entanto, verificou-se maior acúmulo de proteína em plantas cujas sementes tinham uma menor relação comprimento/largura de grão.–Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAraújo, Elisangela Sousa deSouza, Sonia Regina deFernandes, Manlio Silvestre2003-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6701Pesquisa Agropecuaria Brasileira; v.38, n.11, nov. 2003; 1281-1288Pesquisa Agropecuária Brasileira; v.38, n.11, nov. 2003; 1281-12881678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6701/3758info:eu-repo/semantics/openAccess2014-08-11T19:42:32Zoai:ojs.seer.sct.embrapa.br:article/6701Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-11T19:42:32Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
