Eleven total and broad spectrum herbicides were applied on the whole material of the Maize Research institute (MRI) Gene Bank - Belgrade, in order to search for eventual rare mutants resistant to some of them. Only the resistance to the Pivot herbicide was obviously found (active ingredient imazethapyr), and the genes controlling this trait were dominant. Few modes of inheritance were found for these genes (three complementary dominant genes, two complementary dominant genes and one dominant gene). For practical purposes (incorporation in the non-resistant material), the source of one dominant gene is the most appropriate.
