The development and dissemination of maize (Zea mays L.) hybrids has been an important factor in meeting the increasing worldwide demand for this cereal over the past 30 years. Most national and private breeding programs are investing in hybrid development to increase domestic maize production, both for domestic consumption and export (Castellanos et al. l998). One of the main problems facing breeders of maize hybrids is the inbreeding depression usually expressed in the inbred lines used as parents. Modified single-cross hybrids, in which either one or both parents are crosses of related lines (Hallauer and Miranda 1988), offer a potentially attractive altemative to lower the costs of hybrid seed production. This study was designed to generate information about this approach, as a way of accelerating the use of maize hybrids in developing countries.
