This article, which is a follow-up to one where maize germplasm collection and obtention of improved Creole varieties were shown, is presented with the somewhat historic objective of showing that the professional improvers of this plant in our country have continued to work in the development of corn hybrids of different types: from double to simple crosses, including trilinear hybrids and synthetic varieties. This review about recent hybrids shows that maize regions in México have not been left unattended, from the important irrigation areas in the center, northwest and northeast, to the south and southeastern regions where rainfed agriculture prevails, not less important than the former. We insist in the fact that with the production of new hybrids, the general seed price will tend to be balanced in relation to those of commercial companies, and we highlight two relevant problems with the development of transgenic hybrids: contamination of Creole varieties and the health of consumers.
