Using the standard method, we studied the germination energy of seed of seven different sunflower genotypes (five hybrids and two cytoplasmically male sterile female lines) developed at the Institute of Field and Vegetable Crops in Novi Sad. The seed was treated with the fungicides benomil, metalaxyl and fludioxonil and the insecticides thiamethoxam and imidacloprid and kept for a year in a storage facility. Analysis of variance showed that there were highly significant differences among the genotypes, chemical treatments, and storage periods. Highly significant differences were also recorded for all the interactions among the factors studied. On average, the highest germination energy was found in the hybrid H2 (93.45%), whose values of this parameter were highly significantly higher than those of the rest of the genotypes, except for the hybrid H1. Also, each of the hybrids had highly significantly higher germination energy than either of the two lines, and the differences among the hybrids themselves were highly significant. Looking at the chemical treatments, the control had the highest germination energy by a highly significant margin (80.39%). The largest difference was observed in relation to the treatments with insecticides (5.48 and 9.56%). These treatments had highly significantly lower values of germination energy than those involving fungicides. Germination energy increased in the first nine months of storage, peaking at 81.29%. After that, there was a sharp drop to 68.94% after 12 months of storing. Differences among the different storage periods were all highly significant except for that between six and nine months of storage, which was not statistically significant.U radu je standardnom metodom ispitivana energija klijanja semena sedam različitih genotipova suncokreta, dve citoplazmatski muško sterilne forme linije majke i pet hibrida, stvorenih u Institutu za ratarstvo i povrtarstvo iz Novog Sada. Seme je tretirano fungicidima: benomil, metalaksil i fludioksonil, kao i insekticidima: tiametoksam i imidakloprid i čuvano godinu dana u skladištu. Analizom varijanse utvrđene su visoko značajne razlike između ispitivanih genotipova, hemijskih tretmana i dužina čuvanja. Ustanovljene su i visoko značajne razlike za sve interakcije ispitivanih faktora. U proseku, najveću energiju klijanja imao je hibrid H2 (93,45%), čija je vrednost bila je statistički visoko značajno veća nego kod ostalih genotipova, osim u odnosu na vrednost kod hibrida H1. Takođe, može se zaključiti da su svi hibridi imali visoko značajno veću energiju klijanja semena od linija kao i da su između ostalih ispitivanih hibrida razlike bile visoko značajne. Kod hemijskih tretmana energija klijanja u kontroli bila je visoko značajno najveća i iznosila je 80,39%. Najveća razlika bila je u odnosu na tretmane sa insekticidima (5,48% i 9,56%). Vrednost ispitivanog parametra kod ovih tretmana bila je i visoko značajno manja u odnosu na vrednosti dobijene kod tretmana sa fungicidima. Energija klijanja povećavala se sve do devetog meseca kada je i zabeležena najveća vrednost (81,29%), a zatim dolazi do naglog pada nakon dvanaest meseci čuvanja gde je zabeležena vrednost od 68,94%. Između svih ispitivanih varijanti su bile visoko značajne razlike, jedino razlika između šest i devet meseci čuvanja nije bila statistički značajna
