Popis: This study was done as a part of the studies carried out on breedingpotato varieties adaptable to central-north intersectional region. This studyhas been started in 2007, with about 20 thousand hybrid potato seedlings and asa result of clonal selection, 20 clones, performing excellent characteristicsin terms of yield and quality characteristics, were subjected to the analysis ofstability in terms of genotype x environment interactions. The study wasconducted under Tokat-Niksar, Tokat-Kazova (2012-2013) and Tokat-Artova(between 2011-2012 and 2012-2013) conditions as a randomized complete blockdesign with 3 replications in 8 different environments, as the year andlocation are accepted as an environment. In the study, four commercialvarieties were tested as standards beside White, cream, light yellow and darkyellow clones. The data were subjected regression analysis. Based on the Finlay-Wilkinson regressioncoefficients, some of the clones (A7-12, T5-4, T11-10, T5-14, A3-15, A3-167,and T10-8) which have better yield and quality characteristics than commercialvarieties, showed good adaptation to specific environments while the clones(T6-28 and A3-234) had good adaptation to all the environments (Tokat-Niksar,Tokat-Kazova, and Tokat-Artova). Also in terms of dry matter, A13-1 has beenidentified as a clone with higher (28.4%) dry matter contents.
