Maize breeding in Maize research institute “Zemun Polje” was conducted for more than 75 years resulting in the creations of numerous maize hybrids with superior traits and performance. The source breeding material used in the breeding programs was very diverse and varied from the domestic landraces to the introduced inbred lines. This resulted in a very diverse and complex structure of the breeding pools used in commercial maize breeding in “Zemun Polje” Institute. As genetic material in this study, 24 maize inbred lines of different origin, heterotic and maturity goups were selected were selected from the 3rd and 4th cycle of breeding in Maize research institute “Zemun Polje”. These are inbreds that were commonly used in breeding programs during the 1980s and were parental components of most important commercial maize hybrids. The genotyping was performed using a Maize 25k Infinium array. The neighbor-joining cladogram, PcoA and Structure were used to analyze the genetic structure and... diversity of the panel. Population structure analysis of the panel initially showed a clear divide between Lancaster and Non-Lancaster inbred lines, revealing the dominant heterotic pattern in the breeding program. Further analysis with an increased number of population (k) showed a more complex structure of the non-Lancaster group of inbred lines with best number of ancestral population being k=5. The average genetic distance in the panel was 0,385, ranging from 0,039 to 0,544, with paternal inbreds in most of commercial hybrids being the most distant ones. The genotyping results of the Zemun Polje maize panel were further merged with DROPS European panel of 247 dent maize inbred lines in order to view the results of the diversity analysis of the Zemun Polje panel from a broader perspective.
