Abstract :Caprifigs (Ficus carica var. caprificus) are essential for caprification and hybridization studies in cultivated figs, a gynodioecious species. Rising summer temperatures due to global climate change increase the need to evaluate the pollinator properties of caprifigs, especially in regions experiencing sudden temperature fluctuations, such as the Mediterranean region of Türkiye. This study assessed the pollen viability and germination status of selected caprifig genotypes from the Eastern Mediterranean Region of Türkiye. In the study, 20 caprifig genotypes from Adana, Kahramanmaraş, Mersin, and Osmaniye provinces were compared with standard caprifig cultivars (Ak İlek, Armut İlek, Elma İlek, Hamza, Küçük Konkur, and Taşlık). Pollen viability of the caprifig genotypes was evaluated using TTC and FDA tests. Pollen germination was studied in a medium containing 1% agar + 3% sucrose + 100 ppm H3BO3 + 300 ppm Ca(NO3)2 + 200 ppm MgSO4 + 100 ppm KNO3. Pollen viability values ranged from 67.05% to 98.60% in the TTC test and from 70.75% to 94.32% in the FDA test. Pollen germination values ranged from 30.22% to 88.90%. As a result, the Kahramanmaraş07, Mersin01, and Osmaniye08 genotypes selected from the natural population of the Eastern Mediterranean Region of Türkiye were as valuable as standard cultivars in terms of pollen viability and germination properties.
