Resumo: | The objective of this article was to estimate the genetic variability and selection gain in the characters related with fruits in assai palms, 68 progenies collected in populations from Afuá city and planted in Amapá state were evaluated. The experiment was conducted in random blocks with two replications and four useful plants per plot. The following characters were evaluated: fruit longitudinal diameter (DLF), the fruit greatest transversal diameter (DTMA), the smallest fruit diameter (DTME); mass from one hundred fruits (P100) and, in bunches: total fruit mass (PTC). There are differences between progenies, denoting the possibility of selection gains. In general, the inheritabilities were medium or high for the characters, but always lower for PTC. The coefficient CVg/CVe was favorable in DTMA and DTME and unfavorable to PTC; the correlations between characters were positive and significant, the selection gain was 16.65% for PTC and from -1.29% to -7.60% in the other characters; the selected progenies were able to associate the desired values in the evaluated characters. The obtained conclusions were that there is high environmental contribution in the phenotypic manifestation of the progenies once the fruit metric dimensions had lower environmental effects and higher genetic effect; there is possibility of genetic gains which are important to breeding programs of this species using the characters simultaneously, although the values had been low, mainly due to the positive correlation presence, where there is preference for reduced fruit size with productivity increase. |

O experimento foi instalado em blocos ao acaso com duas repetições e quatro plantas úteis por parcela. Foram avaliados os caracteres: diâmetro longitudinal do fruto (DLF); maior diâmetro transversal do fruto (DTMA); menor diâmetro transversal do fruto (DTME); massa de cem frutos (P100) e massa total de frutos no cacho (PTC). Há diferenças significativas entre progênies, o que denota possibilidade de ganhos com a seleção. Em geral, as herdabilidades na média de progênies foram de médias a altas para os caracteres, mas sempre menor para PTC. A relação CVg/CVe foi favorável em DMA e DTME e desfavorável para PTC; as correlações entre os caracteres foram positivas e significativas; o ganho de seleção foi de 16,65% para PTC e entre -1,29% e -7,60%, nos demais caracteres; as progênies selecionadas conseguiram associar os valores desejados nos caracteres avaliados. As conclusões obtidas foram de que há elevada contribuição ambiental na manifestação fenotípica das progênies, sendo que as dimensões métricas dos frutos sofreram menores efeitos ambientais e maior efeito genético; há possibilidade de ganhos genéticos importantes aos programas de melhoramento genético da espécie utilizando-se os caracteres de forma simultânea, apesar de os valores obtidos terem sido baixos, principalmente devido à presença de correlações positivas, nas quais há preferência da redução do tamanho do fruto com aumento de produtividade.Universidade Federal de Santa Maria2016-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2422710.5902/1980509824227Ciência Florestal; Vol. 26 No. 3 (2016); 985-993Ciência Florestal; v. 26 n. 3 (2016); 985-9931980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/24227/14180Copyright (c) 2016 Ciência Florestalinfo:eu-repo/semantics/openAccessYokomizo, Gilberto Ken-ItiMochiutti, SilasQueiroz, José Antônio Leite deSantos, George Reis dosFurtado, Renan GomesBrandão, Ancelma PereiraColares, Irecê Bezerra2017-04-06T13:30:29Zoai:ojs.pkp.sfu.ca:article/24227Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-06T13:30:29Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
