Hetrosis or hybrid vigor is the superior performance of the F1 population with respect to their parents and hence it is a measure for evaluating a set of hybrids and their parents. It is expected to a higher heterosis a higher total yield. This study was done with the objective of providing basic information of the agronomic behavior of five maize hybrid varieties of different genetic and geographical diversity. The experimental material was planted at the C.N.I. Tibaitata, located in Mosquera at 2543 m.a.s.l. In general it was found heterosis in the hybrid varieties studied and because the high yield, prolificacy and the prominent agronomic qualities, the hybrids MB515 X ICA V 155 and MB515 X ICA V 453 were suggested as promisories genetic resources in future breeding programs.
