Resumo: Half-sib progenies obtained from 5 different clones were compared for their merits as rootstocks in nursery also including a study of correlation between each pair of the following variables: plant height, number of leaf flushes and stem diameter at 5 cm above ground. Data were taken at the age of 12 months, in a randomised block experiment with 4 replications, where 10 competitive plants were chosen for the measurements. The results showed that seedlings from IAN 717 and IAN 873, among the clones studied, must be preferably chosen as a source of seed rootstocks. Fx 3899 gave the poor results. Plant height and girth appear to be the best pair of correlated characters. The low heritability of the 3 characters studied indicate that they are highly dependent on enviromental conditions.

Foram utilizadas progênies de meios-irmãos oriundas de 5 clones de seringueira. O delineamento experimental empregado foi o de blocos ao acaso, com 4 repetições e 10 plantas competitivas na área útil da parcela. Os dados foram retirados aos 12 meses de idade das plantas, sendo estudados os caracteres de altura de planta, diâmetros do caule a 5 cm do solo e número de lançamentos. Os resultados mostraram, entre outros fatores, que plântulas do clone IAN 717 e do IAN 873 podem ser utilizadas com sucesso como porta-enxertos, enquanto que as oriundas do Fx 3899 devem ser preteridas. Os caracteres mais correlacionados foram: altura de planta e diâmetro do caule. Os três caracteres apresentam baixa herdabilidade, indicando que são bastante influenciados pelo meio-ambiente.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraValois, Afonso C.C.Pinheiro, EuricoConceição, Heraclito E.O.Silva, Maria N.C.2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16769Pesquisa Agropecuaria Brasileira; v.13, n.2, fev. 1978; 49-54Pesquisa Agropecuária Brasileira; v.13, n.2, fev. 1978; 49-541678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16769/11092info:eu-repo/semantics/openAccess2014-04-15T19:14:29Zoai:ojs.seer.sct.embrapa.br:article/16769Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:14:29Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
