Abstract :This study aimed to determine the potato breeding lines that show superior storage traits and can be candidate variety by selection. The storage study was carried out in the first year according to The Randomized Plots Trial Design and the second year according to The Randomized Plots in Factorial Trial Design with four replications. In the study, 20 potato breeding lines developed by Selcuk University, Faculty of Agriculture, Department of Field Crops and 18 registered varieties as plant material were used in the first year. In the second year, the study continued with 7 breeding lines and 8 registered varieties that selected in the first year. The varieties and lines were done harvest in the fields and then the genotypes were evaluated according to physical and quality traits with storage trials insert ignore into journalissuearticles values(+ 4 °C, 6 months);. In the study; ratio of dry matter insert ignore into journalissuearticles values(%);, yield of leaf chips insert ignore into journalissuearticles values(%);, yield of French fries insert ignore into journalissuearticles values(%);, quality of leaf chips insert ignore into journalissuearticles values(1-5 scale);, quality of French fries insert ignore into journalissuearticles values(0-4 scale);, blackening insert ignore into journalissuearticles values(1-5 scale);, storage weight loss insert ignore into journalissuearticles values(%);, the first shoot formation time insert ignore into journalissuearticles values(day); parameters were examined. The ratio of dry matter, yield of leaf chips, and French fries values increased compared to the pre-storage period. Among the promising lines in terms of dry matter ratio changes; T7LA8 insert ignore into journalissuearticles values(20.9 %-24.8 % in 2019,19.0 %-21.1 % in 2020 according to the genotype average values);, PAG5 insert ignore into journalissuearticles values(22.6 %-20.5 % in 2019, 20.0 %-19.0 % in 2020 according to the genotype average values);, GAF4 insert ignore into journalissuearticles values(18.7 %-21.6 % in 2019, 18.4 %-20.7 % in 2020 according to the genotype average values); can be counted. As a result of the study, T7LA8, PAG5 and GAF4 lines with high ratio of dry matter, yields of chips and French fries were determined as promising lines.
