Resumo: The macaw palm (Acrocomia aculeate) is an extraction oil palm and its fruit is of great socioeconomic importance for small farmers. The aim of this study was to evaluate the genetic variability and to obtain information about the genetic control of morphological traits related to growth and vigor of macaw palm. Fifty-one open pollinated progenies were collected in Minas Gerais and São Paulo States, which are active members of the germplasm bank of Viçosa Federal University. These 51 progenies, twelve months after planting, were evaluated for plant growth and number of leaves emitted. The characteristics evaluated presented great variability among the progenies. Heritability coefficient of 87% and 48% were obtained for plant growth and leaf number emitted, respectively, revealing a high degree of genetic control and potential for the genetic breeding. The Tocher’s method was efficient to allocate progenies from State of São Paulo in the same group. The rank index selection method allowed the selection of more balanced progenies and individuals for the two traits, making possible to optimize the selection and obtain gains in all traits simultaneously.

O objetivo deste trabalho foi avaliar a variabilidade genética e obter informações sobre o controle genético de características morfológicas relacionadas ao crescimento e vigor da macaúba. Foram coletadas 51 progênies em Minas Gerais e São Paulo, as quais são integrantes do banco ativo de germoplasma da Universidade Federal de Viçosa. Doze meses após o plantio, essas progênies foram avaliadas quanto ao crescimento da planta (cm) e número de folhas emitidas. Estas características apresentaram grande variabilidade entre as progênies. As estimativas dos coeficientes de herdabilidade foram de 87% e 48%, para crescimento de planta e número de folhas, respectivamente, revelando controle genético e boas perspectivas para o melhoramento. O método de Tocher mostrou-se eficiente em alocar as progênies do Estado de São Paulo em um mesmo grupo. O método de seleção pelo Índice de rank médio permitiu selecionar indivíduos e progênies mais equilibrados em termos dos dois caracteres.Embrapa Florestas2012-03-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/28310.4336/2012.pfb.32.69.63Pesquisa Florestal Brasileira; v. 32 n. 69 (2012): jan./mar.; 63Pesquisa Florestal Brasileira; Vol. 32 No. 69 (2012): jan./mar.; 631983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/283/247Copyright (c) 2012 Candida Elisa Manfio, Sérgio Yoshimitsu Motoike, Marcos Deon Vilela de Resende, Carlos Eduardo Magalhães dos Santos, Aurora Yoshiko Satohttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessManfio, Candida ElisaMotoike, Sérgio YoshimitsuResende, Marcos Deon Vilela deSantos, Carlos Eduardo Magalhães dosSato, Aurora Yoshiko2017-04-28T12:57:12Zoai:pfb.cnpf.embrapa.br/pfb:article/283Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T12:57:12Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
