Descrição: The objective of this study were to estimate selection, simultaneous selection of independent characters, and genetics gain, in a recurrent selection program of full-sib families in two corn populations. We evaluated 81 families under irrigation of two native populations of Pinto Amarillo of maize numbers "15" and "45" at the experimental field of the Faculty of Agronomy of the UANL, México. The experimental design was a 9x9 alfa-lattice with three replications; the study variables included plant height, ear height, days to male and female flowering, grain yield, ear length, ear diameter and number of rows per ear. The selection indexes were more efficient because they involved up to seven characters associated to grain yield, mostly plant height, days to male flowering, ear diameter, number of rows per ear and ear length.
