In a maize (Zea mays L.) breeding program by hybridization it is important to have a reliable and efficient tester for the general combining ability (GCA) of maize inbred lines. With the aim to contribute more experimental evidence relative to the identification of the best tester of GCA of maize inbred lines, in this study 50 S1 lines derived from the Compuesto Universal original (original variety), plus four lines of high and four of low GCA derived from populations of Xolache and Mex.
