Abstract :Potato is one of the mos t important crops worldwide. The present s tudy was conducted in Yuksel Seed R&D Center, Antalya. Approximately 120.000 seeds from different genetic backgrounds were obtained and evaluated between 2008 and 2016 for developing new varieties. The aim of the research was to develop superior potato varieties tolerant to PVY and PVX with high agronomic, tuber and quality traits. Potato virus Y insert ignore into journalissuearticles values(PVY); and Potato virus X insert ignore into journalissuearticles values(PVX); are among the mos t important viruses, causing economic crop losses in potato crop in the world. The use of resis tance genes is the mos t effective method to control these viruses. Resis tance genes are transferred to new commercial varieties using molecular markers that are tightly linked to resis tance genes insert ignore into journalissuearticles values(Ryadg for PVY, Rx1 and Rx2 for PVX);. Potato lines were tes ted in replicated trials in different potato regions of Turkey insert ignore into journalissuearticles values(Adana, İzmir, Afyonkarahisar, Niğde, Nevşehir and Kütahya); by 8 years to es timate the genotype x environment interaction and 85 superior lines were selected. At the end of the research 4 early season and 3 main season superior lines were submitted for regis tration as commercial varieties and 4 of 7 candidate commercial varieties were determined as suitable for French fries and were marketed.
