Abstract Turkey, which is in the second rate of the world citrus exporters, exports 94% of the total citrus export to East Europe markets (esp. Russian, Ukraine, Romania, Poland, Bulgarian etc.) and some Middle East countries (Iraq, Saudi Arabia, Persia, etc.). The consumer reflexes have not fully expanded in those countries yet. Therefore, the risk of losing export markets is increasing in recent years. This study aims to develop new citrus varieties in order to hold on in the risky export market; re-enter a stable and better importer markets of Western Europe; and find new markets. In order to improve mid-late ripening mandarins; early and late ripening Navel oranges; early ripening and resistant Mal secco resistant lemon varieties by mutation breeding; 13 orange, mandarin and lemon scions were irradiated with Co60 sourced gamma ray in Ankara Atomic Energy Institute. After irradiation buds on scions were grafted to sour orange. After M1V1 scions were re-grafted to obtain M1V2 step. Besides 37 combinations were crossed in order to improve mid-late ripening new mandarin varieties. Seeds obtained from crossing were germinated and the population with hybrids were established.
