Abstract	During 2000-01, an attempt to determine the dormancy of seeds of five triticale cultivars was made. Germination was evaluated at 10, 15, 20 and 25(deg)C, and seeds were sown at two dates, 4 and 14 days after harvest. The greatest effect of temperature was found when the average germination time was determined (using Pieper's method), the values of which decreased with an increase in temperature from 10 to 25(deg)C. Under the same conditions, a decrease in germination capacity at the first evaluation date was observed. When evaluation was done at a later date, a significant effect of weather conditions on the level of seed dormancy was found. Two cultivars, Kargo and Migo, were characterized by the highest level of dormancy, while cultivars Gabo and Wanad showed a low level of dormancy. The values of the estimated dormancy index were very low, from 0.06 to 0.15, which indicates its poor usability for the evaluation of triticale seeds, considering the fact that triticale is characterized by a low dormancy level
