Resumo: The objective of this work was to estimate the genetic parameters, correlations, and selection gains for the oil production of interspecific hybrids progenies between American oil palm, of 'Manicoré' origin, and oil palm, of 'La Mé' origin. Thirty-nine progenies were evaluated from the sixth to the ninth year after planting, for the productivity of fresh fruit bunches (PROD_FFB), oil content in the bunch (OCB), and palm oil productivity (PROD_OP). The genetic parameters and gains from direct (GDS) and indirect (GIS) selection were estimated for PROD_OP. High values of heritability for the CVg/CVe ratio indicated favorable conditions for the selection. With the selection of 20% of the progenies (selection in both sexes), the following estimates were obtained: 11.15% GDS for PROD_OP, 9.1% GIS for OCB, and 8.1% GIS for PROD_FFB. The PROD_OP of the progenies was of 6,175, 6,057, and 5,995 kg ha-1 per year with GDS and GIS for OCB and PROD_FFB, respectively. The restricted selection of the LM2T male genitor offspring resulted in 5.1% estimated GSD and in a mean of 5,800 kg ha-1 per year for PROD_OP. Selection gains for PROD_OP can be achieved immediately through the selection restricted to oil palm male genitors, and, in the medium and long term, through the interspecific reciprocal recurrent selection between American oil palm and oil palm populations.

Trinta e nove progênies foram avaliadas, do sexto ao nono ano pós-plantio, quanto a produtividade de cachos de frutos frescos (PROD_FFB), teor de óleo no cacho (OCB) e produtividade de óleo de palma (PROD_OP). Foram estimados os parâmetros genéticos e os ganhos de seleção direta (GDS) e indireta (GIS) para PROD_OP. Altos valores de herdabilidade para a razão CVg/CVe indicaram condições favoráveis para a seleção. Com a seleção de 20% das progênies (seleção em ambos os sexos), as seguintes estimativas foram obtidas: 11,15% de GDS para PROD_OP, 9,1% GIS para OCB e 8,1% GIS para PROD_FFB, respectivamente. A PROD_OP das progênies foi de 6.175, 6.057 e 5.995 kg ha-1 por ano, com GSD e GSI em OCB e PROD_CFF, respectivamente. A seleção restrita a genitores masculinos de dendê LM2T resultou em 5,1% de GSD e na média de 5.800 kg ha-1 por ano para PROD_OP. Ganhos de seleção para PROD_OP podem ser obtidos imediatamente pela seleção restrita de genitores masculinos de dendê e, em médio e longo prazo, pela seleção recorrente recíproca interes­pecífica entre as populações de caiaué e dendê.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraConselho Nacional de Desenvolvimento Científico e TecnológicoFundação Amazônia de Amparo a Estudos e PesquisasEmbrapaMarborges GroupConselho Nacional de Desenvolvimento Científico e TecnológicoFundação Amazônia de Amparo a Estudos e PesquisasEmbrapaGrupo MarborgesGomes Junior, Rui AlbertoFreitas, Alessandra Ferraiolo deCunha, Raimundo Nonato Vieira daPina, Antônio José de AbreuCampos, Higo Otávio BrochadoLopes, Ricardo2022-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/26987Pesquisa Agropecuaria Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e02321Pesquisa Agropecuária Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e023211678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/26987/14946Direitos autorais 2022 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2022-05-18T18:27:35Zoai:ojs.seer.sct.embrapa.br:article/26987Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2022-05-18T18:27:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
