DETERMINATION OF YIELD PERFORMANCE OF EARLY AND MAIN SEASON POTATO COMMERCIAL CANDIDATE VARIETIES

In this research, about 115.000 potato seeds from different genetic backgrounds obtained and evaluated 2008 to 2015 for developing new varieties. At the end of 9 years potato breeding program 7 advanced potato lines (The early season: 12-03-85, 12-55-07, 12-55-16, 12-69-39; main season: 12-68-05, 13-67-25 and 22-99-33) submitted for registration as commercial varieties. The aim at the research compared to performance of early and main season commercial candidate potato varieties with commercial varieties for agronomic, tuber and quality traits. 7 commercial candidate potato variety tested in 4 replicated trials in four potato regions of Turkey (For the early season, Adana and Izmir; for the main season, Antalya and Nigde). As a result, 4 of seven candidate commercial varieties determined as a suitable for French fries, chips and fresh potato market. In the first step, these 7 commercial candidate varieties will be using large-scale in Turkey, after that these varieties can use other countries such as Morocco, Pakistan, Azerbaijan and other Turkic Republics, South Korea, etc.
