Evaluation of Physical and Quality Traits of Local Potato Breeding Lines During Long Term Storage

Nursel Çöl Keskin, Rahim Ada


The purpose of this study was 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 The Randomized Plots Trial Design and in 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 at 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 (+ 4 °C, 6 months). In the study; ratio of dry matter (%), yield of leaf chips (%), yield of French fries (%), quality of leaf chips (1-5 scale), quality of French fries (0-4 scale), blackening (1-5 scale), storage weight loss (%), the first shoot formation time (day) parameters were examined. The ratio of dry matter, yield of leaf chips and yield of French fries values increased compared to the pre-storage period. Among the promising lines in terms of dry matter ratio changes; T7LA8 (20.9 %-24.8 % in 2019,19.0 %-21.1 % in 2020 according to the genotype average values), PAG5 (22.6 %-20.5 % in 2019, 20.0 %-19.0 % in 2020 according to the genotype average values), GAF4 (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.
