Resumo: The objective of this study was to determinate the genetic (rG), phenotypic (rF), and environment (rE) correlations among nine characters of nine rubber tree clones Hevea spp. The experimental design was in randomized complete blocks with nine treatments and three replications. The correlated characters were, dry rubber production by early Hamaker Morris-Mann (HMM) test, total plant height, stem circunference at 1,30 m and 0,50 m from the point of insertion of the graft, bark thickness, total number of latex vessels rings, diameter of latex vessels, density of latex vessels per 5 mm rings, and average distance between consecutives latex vessels. The genetic and phenotypic correlation coefficients estimation indicated that the characters most correlated with rubber production were, barck thickness (rG = 0,7234; rF = 0,6923) and latex vessels rings number (rG = 0,6829; rF - 0,6005), showing that both traits are quite important in rubber trees improvement programs.

Os caracteres correlacionados foram: produção de borracha seca através do teste precoce Hamaker Morris-Mann (HMM), altura total da planta, circunferência do caule a 1,30 m e 0,50 m da soldadura do enxerto, espessura de casca, número de anéis de vasos laticíferos, diâmetro dos vasos laticíferos, densidade dos vasos em 5 mm do anel e distância média entre os consecutivos anéis de vasos laticíferos. As estimativas dos coeficientes de correlação genética e fenotípica evidenciaram que os caracteres mais correlacionados com a produção foram: espessura de casca (rG = 0,7234; rF = 0,6923) e número de anéis de vasos laticíferos (rG = 0,6829; rF = 0,6005), mostrando serem estes de grande importância no melhoramento genético da seringueira.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRibeiro, Sydney ItauranVentorim, NelsonPereira, PériclesBueno, Luis C. de S.2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16125Pesquisa Agropecuaria Brasileira; v.19, n.10, out. 1984; 1235-1245Pesquisa Agropecuária Brasileira; v.19, n.10, out. 1984; 1235-12451678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16125/10280info:eu-repo/semantics/openAccess2014-04-16T19:09:29Zoai:ojs.seer.sct.embrapa.br:article/16125Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:09:29Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
