The aim of this study was to obtain superior fig (Ficus carica L., 2n=2x=26, gynodioecious, Moraceae) cultivars. The research was carried out at the Fig Research Institute, Erbeyli, İncirliova, Aydın, Turkey in 2010. Four different hand-made crosses were performed between fig cultivars. One of these crosses was between 'Sarılop' (female, Smyrna) and 'Kaba ilek' (male, profichi) fig cultivars. Hybrid seeds belonging to this cross were germinated in proper conditions and small plantlets were grown. In 2014 these young hybrids were planted in the orchard with a spacing of 3.00×1.25 m. To select superior genotypes, pomological features will be measured as soon as these hybrids will begin to bear fruits. Some leaf characteristics were investigated on 350 hybrid fig plants in 2014. In 2015, the values measured, respectively, for 'Sarılop', 'Kaba ilek', and hybrids, were the following: central lobe length (13.2, 9.8, 10.9 cm), leaf length (21.2, 18.8, 15.6 cm), central leaf length/leaf length (0.62, 0.52, 0.70), leaf width (19.2, 16.2, 14.0 cm), leaf area (407.5, 304.9, 227.0 cm2), petiole length (6.8, 7.9, 4.7 cm), petiole length/leaf length (0.32, 0.42, 0.30), and petiole thickness (4.03, 4.25, 3.12 mm). The highest positive significant correlation (0.95) was between leaf area and leaf length, and leaf area and leaf width. Except central lobe length, the values of leaf length, width, and area, petiole length and thickness were lower than parents. This might indicate that negative transgressive segregation exists in latter mentioned leaf characteristics in 'Sarılop' × 'Kaba ilek' fig cross.
