Resumo: The objective of this work was to estimate genetic parameters of traits at the juvenile stage of different assai palm (Euterpe oleracea) tree progenies, as well as to select among and within the most promising for fruit production. A total of 34 half-sib and 16 full-sib progenies were evaluated in a completely randomized design with eight replicates and one plant per plot. Nine traits were measured in five harvests, and the data were analyzed using the mixed model approach. The genetic variance was significant for most of the traits. Progeny-mean heritabilities showed moderate magnitudes, ranging from 51% for number of dead leaves to 59% for leaf sheath length. In general, the genetic correlations were positive and had magnitudes varying from moderate to very high. The genetic gains were more expressive for the traits plant height, leaf sheath length, and girth circumference. The full-sib progenies P33, P37, and P42 are promising for fruit production.

Foram avaliadas 34 progênies de meios-irmãos e 16 progênies de irmãos germanos no delineamento inteiramente casualizado, com oito repetições e parcela de uma planta. Nove caracteres foram mensurados em cinco colheitas, e os dados foram avaliados por meio da abordagem de modelos mistos. A variância genética foi significativa para a maioria dos caracteres. As herdabilidades na média de progênies exibiram magnitudes moderadas, com variação de 51% para número de folhas mortas a 59% para comprimento da bainha foliar. Em geral, as correlações genéticas entre os caracteres foram positivas e com magnitudes de moderada a muito alta. Os ganhos genéticos foram mais expressivos para os caracteres altura de planta, comprimento da bainha foliar e comprimento do coleto. As progênies de irmãos germanos P33, P37 e P42 mostraram-se promissoras para produção de frutos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraEmbrapa Amazônia Oriental, to the graduate plant breeding and genetics program of Universidade Federal de Lavras (Ufla)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes)Navegantes, Patricia Cardoso AndradeOliveira, Maria do Socorro Padilha deNunes, José Airton Rodrigues2018-10-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/26088Pesquisa Agropecuaria Brasileira; v.53, n.7, jul. 2018; 815-823Pesquisa Agropecuária Brasileira; v.53, n.7, jul. 2018; 815-8231678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/26088/14249https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/26088/17766Direitos autorais 2018 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2018-10-09T16:25:54Zoai:ojs.seer.sct.embrapa.br:article/26088Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2018-10-09T16:25:54Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
