Maize is characterised with high diversity, which is at the same time maintained in present gene banks of plants. From that point, the application of the present ability of maize genetic variability could be used for creating of the genotypes with changed chemical composition of the grain. The aim of experiment was to examine the influence of different factors on variability of inorganic and phytic phosphorus in grain of nine ZP hybrids and their parental components. The experiment was performed during 2010 and 2011 on two locations of the Maize Research Institute. The higher values of phytic and inorganic P were mainly present at lines in 2010, as well as at ZP 341 and ZP 434 hybrids, as well as at their parental components. Among all examined hybrids, the significant differences in phytic P, influenced by season were present at ZP 434 and ZP 555, as well as mother component of ZP 555. The both parental components show significant and positive impact on inorganic P increase in hybrid grain. The eligible increase of available P. with decrease of phytic P, could be effective obtained by using of the genetic resources in prebreeding process4e, with recurent selection.
