Resumo: Aiming to estimate the gain prediction by using selection indexes on cycle C4 of UNB-2U, two hundred progenies of full-sib families were obtained on the third cycle under recurrent selection. The progenies were evaluated in a randomized complete block design with two replications within sets, in two distinct environments: Colégio Estadual Agrícola Antônio Sarlo, located in Campos dos Goytacazes, and Experimental Station of PESAGRO-Rio, located in Itaocara, Rio de Janeiro State. The utilized selection indexes were the Smith (1936) and Hazel (1943), Pesek and Baker (1969), Williams (1962), and Mulamba and Mock (1978). The selection index of Mulamba and Mock (1978) allowed the prediction of negative gains for number of disease ears, number of ears attacked by insects, number of broken plants, poorly hulled ears; and it provided superior gains for popcorn expansion and grain yield, with values of 10.55% and 8.50%, respectively, in the use of arbitrary weights attributed by tentative.

As progênies foram avaliadas no delineamento de blocos casualizados com duas repetições dentro de ‘‘sets’’ em dois ambientes distintos: Colégio Estadual Agrícola Antônio Sarlo, em Campos dos Goytacazes, e Estação Experimental da PESAGRO-RIO, em Itaocara, Rio de Janeiro. Os índices de seleção empregados para predizer os ganhos foram os de Mulamba e Mock (1978), Pesek e Baker (1969), Smith (1936) e Hazel (1943) e Williams (1962). O índice de seleção Mulamba e Mock (1978) além de permitir a predição de ganhos negativos para número de espigas doentes e atacadas por pragas, número de plantas quebradas e acamadas, e espigas mal empalhadas; para capacidade de expansão e rendimento dos grãos, proporcionou ganhos superiores aos demais índices, com valores respectivos de 10,55% e 8,50%, na utilização de pesos arbitrários atribuídos por tentativas.UEL2009-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/407510.5433/1679-0359.2009v30n4p803Semina: Ciências Agrárias; Vol. 30 No. 4 (2009); 803-814Semina: Ciências Agrárias; v. 30 n. 4 (2009); 803-8141679-03591676-546Xreponame:Semina.
