Summary: CIMMYT Maize Program has been providing the national maize program in Venezuela with normal and quality protein maize (QPM) lines and populations developed by this institution. In the last years several white com hybrids formed from CIMMYT lines and several maize populations have been evaluated in different environments, allowing us to identify high yield genotypes well-adapted to the main producer regions of the country. The main objective of this study was to determine the yield stability of nine maize cultivars, both normal and QPM endosperm, evaluated in major Venezuelan corn producing states, using the additive main effects and multiplicative interactions (AMMI) model.
