Resumo: With the objective of evaluating performance, variability and associations between characters, a randomized block experiment was carried out at Piracicaba, São Paulo, Brazil, to compare twenty-one populations of Centrosema pubescens Benth. The characters analysed were: green matter yield, dry matter yield, number of main stems, length of main stem, mean internode length, number of pods per plant. The result obtained demonstrated the existence of high genetic variability for the characters studied. High phenotypic correlations were observed between most of the characters and that in some cases the environmental correlations were significant. Under the conditions of this experiment the populations EEI-35/76, IZ-243, IZ-245, IZ-246, IZ-345, IZ-724 and the cv. Deodoro were the most promising on account of good vegetative development and high seed production.

Os caracteres analisados foram: produção de matéria verde, produção de matéria seca, número de ramificações primárias, comprimento da ramificação primárias, comprimento médio do internódio e número de vagens por planta. Os resultados obtidos demostraram a existência de alta variabilidade genética para os caracteres estudados. Altas correlações fenotípicas foram observadas entre a maioria dos caracteres analisados e, em alguns casos, as correlações ambientais foram significativas. Sob as condições deste experimento, as populações EEI-35/76, IZ-243, IZ-245, IZ-246, IZ-345, IZ-724 e cv. Deodoro foram as mais promissoras, por exibirem bom desenvolvimento vegetativo e alta produção de vagens.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMonteiro, Wilson ReisMartins, Paulo Sodero2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15181Pesquisa Agropecuaria Brasileira; v.18, n.2, fev. 1983; 187-193Pesquisa Agropecuária Brasileira; v.18, n.2, fev. 1983; 187-1931678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15181/8996info:eu-repo/semantics/openAccess2014-04-16T18:50:36Zoai:ojs.seer.sct.embrapa.br:article/15181Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:50:36Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
