Resumo:  In order to increase the efficiency in the production of maize hybrids seeds it is necessary high grain yield with a relative low cost of production. It needs an expansion of the basic knowledge of the heredity of the characters that may be developing new breeding technique. The balanced lethal system (BLS) permit to study the relative contribution of different chromosome segments to hybrid vigour due to the heterocigozity of certain chromosome segments while the rest of the genome go to homocigozity for continuous selfing . In this way, theses segments can be transfer to inbreed lines in order to increase the grain yield and tassel size with pollen production. The objective of this work was to transfer heterotic segments of a line regulated by a balanced lethal system (BLS), through crossing and backcrosses, to an inbred line derivate of a commercial hybrids ACA 2000 of closs pedigree, with the finality of increase the grain yield or pollen production. The variance analysis and principal components showed a significance improvement in the grain yield and tassel size with pollen production in the inbred lines, with the heterotic segment of the BLS line.
