Resumo: Eight characteristics in one year old clones of rubber tree (Hevea spp) were studied. The study included fourteen different clones replicated in two blocks of 25 plants per plot. The data were collected from 500 plants aproximately. Yield by a method of precocious test, total height, stem diameter, bark thickness, total number of latex vessel rings, density of latex vessels per 5 mm per ring, leaf thickness, and total number of fluxes of leaves were measured. Phenotypic and genetic correlations between the characteristics as well as heritability in the broad sense and expected gain due to selection among clones were obtained. The results showed that production is phenotypic and genetic correlated with total height and bark thickness. Except for total height, stem diameter and bark thickness, the heritability of all characteristics studied indicated that they are not dependent on environmental conditions.

Também foram estimados os coeficientes de herdabilidade, no sentido amplo, para as várias características em estudo, bem como os respectivos ganhos genéticos esperados com o emprego da seleção entre clones. Os resultados mostraram, dentre outros fatores, que a produção através do MTP apresentou-se associada com a altura da planta e a espessura de casca, tanto genética como fenotipicamente entre os clones estudados. Excetuando-se altura da planta, diâmetro do caule e espessura de casca, as herdabilidades para as demais características apresentaram-se bastante altas, indicando assim não serem essas características muito influenciadas pelo meio ambiente.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGonçalves, Paulo de SouzaVasconcellos, Maria Elizabeth C.Valois, Afonso Celso CandeiraSilva, Edson Barcellos da2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16491Pesquisa Agropecuaria Brasileira; v.15, n.2, fev. 1980; 129-136Pesquisa Agropecuária Brasileira; v.15, n.2, fev. 1980; 129-1361678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16491/10767info:eu-repo/semantics/openAccess2014-04-15T19:32:16Zoai:ojs.seer.sct.embrapa.br:article/16491Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:32:16Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
