The effect of storage on quality and condition of grain of three wheat cultivars (Ljiljana, Dragana and Simonida) selected in Serbia, was studied. Freshly harvested wheat was stored at 25 deg C for 12 and 20 months. Decreasing of the volume from 812.3 to 727.7 kg/cubic m and absolute mass from 38.5 to 33.0% of wheat grain during storage was recorded. Grain germination in interaction of storage duration and temperature remained at the level above 95%. The interaction of studied factors exhibited no statistically significant effect on the changes in the degree of germination of wheat grain. The changes of the acid degree value (2.0- 2.4 ml 1(NaO)/100 g) were at the level of statistical significance. pH value of fresh samples of grain was 6.5 and after 20 months 5.5. The samples tested from the aspect of their glassiness were homogenous, the value of the coefficient of variation for storage duration was CV less than 10%, and for genotypes CV less than 18%. The storage duration of wheat grain mostly contributed to the increase of the acid degree value, and slightly less the genotype, as well as the interaction of these factors.
