In rose breeding by hybridization, the viable pollen and germination rate of the male parent increases the rate of successful pollination. Therefore, a good variety of pollinators is always needed in hybridization studies. This study was carried out at Ankara University, Faculty of Agriculture, Department of Horticulture to determine pollen viability and germination rates of Magnum, Harmonie and Lady Rose cultivars at three different periods (May, June and July) during flowering. The pollen viability rate was determined by "IKI test" and the pollen germination rate was determined by " saturated petri dish method". According to the data obtained from the study, the pollen viability rate showed significant differences among cultivars and within months. The highest pollen viability rate was observed in Harmonie variety in July (51.00%) and the lowest pollen viability rate was observed in Lady Rose variety in June (16.19%). The highest pollen germination rate was obtained from Harmonie variety with 19.84%. In all three varieties, the highest values in terms of both viable pollen and germination rates were found in July.
