Abstract
The ultimate objective of a crop improvement program is to identify genetically superior genotypes to be used as cultivars. The stability of a cultivar in space and in time is crucial to its practical usefulness over a range environments. Routinely, plant breeders apply recurrent selection techniques to increase frequency of alleles favorable to the quantitative trait of interest and, consequently, to increase probability of being able to identify desirable genotypes. For maize (Zea mays L) there is an option to apply either intra-population or inter-population selection to improve a breeding population.
