Plant breeding cannot be conceived without a high genetic variability. A tool for increasing genetic variability is the modification of the number of chromosomes, i.e. polyploidy, which can enhance the manifestation of agronomically valuable characters. Understanding these manifestations is an important task for genetics and breeding. The aim of the work was to assess the productivity indices of 6 inbred lines of diploid maize and their tetraploid analogues and to assess the interaction of genotype with the ploidy level. The analysis of variance showed that the genotype significantly affects all the studied indices, ploidy insignificantly influences the cob thickness and rachis mass, and the interaction of genotype with ploidy insignificantly affects only the cob thickness. The results obtained can be used in genetic studies and maize breeding programs.
