Starch, protein, and oil are most important storage chemical components in the mature kernels of maize. The aim of this study was to investigate chemical composition of grain of 100 maize inbred, from different heterotic groups. Average content of proteins, oil and starch of analyzed maize inbred lines was, 12,09%, 3,84% and 70,50% respectively. Lines from BSSS germplasm have the lowest content of protein and oil and the highest starch content while the lines from Lankester germplasm have the highest oil content, and lines from European germplasm have the highest protein content and the lowest starch content. Starch concentration is negatively correlated with both protein and oil concentrations in maize grain, while oil concentration has a positive relationship with protein concentration. Two inbred lines with high protein and oil content were distinguished L19 and L77 giving them potential use in breeding programs to improve protein and oil content.
