Aiming to select superior progenies for concentration of favorable alleles in a popcorn population on the third cycle of intrapopulation half-sib recurrent selection, one hundred and ninety-two progenies were evaluated in a completed randomized design with two replications, 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, in 2004/05. The selection intensity was 15.6% that keep in touch thirty half-sib families for the continuity of the breeding program. The utilized selection indexes were the SMITH and HAZEL, PESEK and BAKER, WILLIAMS, and MULAMBA and MOCK. The MULAMBA and MOCK index propitiated more elevated magnitudes of the predicted gains for most of the traits, including popping expansion and grain yield, with values of 7.16% and 10.00%, respectively, utilizing arbitrary weight attributed by tentative.
