Resumo: The objective of this work was to determinate the genotipic determination coefficient, in a wide sense, for nine quantitative characters, in the fix set of nine rubber tree clones. The clones were obtained from crosses and primary selection of Hevea spp. The experimental design was in randomized complete blocks with nine treatments and three replications. The following characters were studied: 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, back thicknees, total number of latex vessels rings, diameter of latex vessels, density of latex vessels per 5 mm rings and average distance between consecutive vessels rings. Genotipic determination coefficient estimates based upon plot means, in a wide sense, were high for all characters, except for diameter of latex vessels. This indicate that both traits are quite important in rubber trees improvement programs.

Os clones utilizados, foram obtidos de cruzamentos e seleção primária de Hevea spp. O delineamento experimental foi o de blocos casualizados, com nove tratamentos e três repetiçôes. Os caracteres estudados foram: produção de borracha seca através do teste precoce Hamaker Morris-Mann (HMM); altura total da planta; circunferências 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 distancia média entre os consecutivos anéis de vasos. As estimativas do coeficiente de determinação genotípica, ao nível de média de parcelas, à exceção do diâmetro dos vasos laticíferos, foram altas, indicando que uma simples seleção fenotípica nesses caracteres poderá ser satisfatória.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/15467Pesquisa Agropecuaria Brasileira; v.19, n.3, mar. 1984; 341-345Pesquisa Agropecuária Brasileira; v.19, n.3, mar. 1984; 341-3451678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15467/9401info:eu-repo/semantics/openAccess2014-04-16T19:18:58Zoai:ojs.seer.sct.embrapa.br:article/15467Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:18:58Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
