Improvement of new fig (Ficus carica L.) cultivars is very important in the of Turkey's fig industry. 'Sarılop', dried fig cultivar and 'Bursa Siyahı', fresh fig cultivar in Turkey are used in this study. It is aimed to obtain new cultivars that are superior (large fruit sized, early ripening, and having small ostiole). Six cobalt gamma radiation doses (0.0, 10.0, 16.9, 25.3, 50.7 and 67.0 Gy) were applied to 25 scions of 6 taken from 'Sarılop' and 'Bursa Siyahı' fig cultivars. M1V1, M1V2, M1V3 plants were obtained via grafting during three years. Shoot growing speed and survival rate of M1V1 (mutation 1 vegetation 1) plants are examined. LD50 values are determined as 50,7 Gy in 'Sarılop', 25,3 Gy in 'Bursa Siyahı'. At the end of the three years, 992 'Sarılop' M1V3 individuals, 836 'Bursa Siyahı' M1V3 individuals and 1828 M1V3 individuals were obtained. These nurseries were planted in 2010 year in the experimental orchard spaced as 3×1,25 m. Growing situation of these individuals is observed and epistatic effect deaths in these individuals are examined. While epistatic effect death is defined the most as 16.60% via 67.0 gray in 'Sarılop' cultivar, this rate is determined the most as 9.82% via 25.3 Gy in 'Bursa Siyahı' fig cultivar.
