Resumo: | The objective of this work was to evaluate the heterotic potential of 14 popcorn populations through topcrosses. In the 1997/1998 crop year, topcrosses hybrids were obtained as a result of crosses between the populations and the tester, which was composed of an equal mixture of seeds from all 14 populations. The populations and the hybrids were evaluated in field, in a randomized block design, with three replications. The estimates for genetic parameters and the topcrosses variance analyses were made. Based on the results of yield and popping expansion of the experiments, the following populations were selected for the syntheses of composite: UEL SI, UEL PAP, UEL ZP, UEL PP, CMS 43 and RS 20. This broad composite is the most promising for use as base populations in breeding programs. |

No ano agrícola 1997/1998, foram obtidos os híbridos topcrosses resultantes dos cruzamentos das populações com o testador, que se constituiu da mistura eqüitativa de sementes de todas as 14 populações. No ano agrícola 1999/2000, as populações e os híbridos foram avaliados em dois experimentos, em delineamento de blocos ao acaso, com três repetições. Foram estimados os parâmetros genéticos, e realizadas as análises de variância dos topcrosses e das populações. Com base nos resultados da capacidade geral de combinação das populações avaliadas nos topcrosses, para os caracteres produtividade e capacidade de expansão, foram selecionadas, para formar o composto amplo, as populações genitoras UEL SI, UEL PAP, UEL ZP, UEL PP, CMS 43 e RS 20. Esse composto apresenta maior potencial para uso como população base no melhoramento.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSeifert, Adilson LuizCarpentieri-Pípolo, ValériaFerreira, Josué MaldonadoGerage, Antônio Carlos2006-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7205Pesquisa Agropecuaria Brasileira; v.41, n.5, maio 2006; 771-778Pesquisa Agropecuária Brasileira; v.41, n.5, maio 2006; 771-7781678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7205/4250info:eu-repo/semantics/openAccess2014-09-29T18:37:28Zoai:ojs.seer.sct.embrapa.br:article/7205Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-29T18:37:28Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
