The aim of this study was to determine the effect of three grain storage times and the cultivar factor on some parameters used in commodity analysis of spring wheat grains. A field experiment was conducted in Czeslawice (Poland) using the split-plot method in 3 replicates in 27 m² plots. This paper presents the effect of storage time (3, 15, 27 months) of grain of four spring wheat cultivars ('Korynta', 'Monsun', 'Tybalt', 'Zadra') on some technological quality characteristics. After harvest, the grains were dried to the moisture content 14% and subsequently stockpiled in a warehouse. It was observed that grains can be stored for a period of even two years with no risk if all the grain storage rules are followed. Short- and long-term grain storage (3-27 months) resulted in satisfactory values of the grain quality characteristics like grain moisture, protein content, and grain hardness index. The storage of grain did not affect negatively grain contamination with mycotoxins. No significant differences were observed in the response of the cultivars studied (grain moisture content, protein content, grain hardness index) to grain storage time. Significant differences among the cultivars were observed in the grain hardness index after 3-month storage. It was also noted that the cultivars 'Korynta' and 'Tybalt' were characterized by lower susceptibility to contamination with mycotoxins than cvs. 'Zadra' and 'Monsun'. The results obtained in this study are a good indicator for cereal producers who store grains for a period of even two years, thus becoming independent of changing price conditions in the cereals market and the changing demand for and supply of animal feed and bread grain across other countries.
