The results of development of maize inbred lines from the commercial hybrids are presented. As a starting material it have been used 45 foreign commercial hybrids from well-known maize companies. The inbred lines were created by the pedigree method. As a result, the 46 new inbred lines from different groups of maturity have been developed. It is revealed that to obtain high yielding hybrids with low kernel moisture it is appropriate to use inbred lines AG6527//04, AG6553/04, AG6251/07, AG6707/07, AG6902/07, AG7050/07, AG6793/07, AG6242/07, AG6515/07, AG6802/07 and AG6906/07, wich have high or medium values of GCA and high values of SCA. The hybrids, which are developed with the new inbreds, have a high degree of plasticity, providing a stable yielding in good and dry years. The hybrids Porumbeni 352, Porumbeni 384, Porumbeni 391, Porumbeni 427 were registered for cultivation in Moldova and Porumbeni 228 – in Belarusi. The new inbred lines can be used to breeding high yielding hybrids or as donors of favorable genes in various breeding programs.
